An Unprecedented Merger that Reoriented India’s Cement Industry: The Story of ACC Ltd.

In the 1930s, Bombay witnessed a significant transformation of its built form. The rise in popularity of new building materials and techniques, including one in particular – Reinforced Cement Concrete (RCC) – was the driver behind this change. RCC’s increased usage during this period was aided considerably by the efforts of a cement company that recognised the scope for its functional qualities. This was the Associated Cement Companies Ltd. (or ACC), formed on August 1st, 1936, as a result of an unprecedented merger of 10 Indian cement companies.[1]
ACC’s emergence coincided with the rise in popularity of RCC buildings; in India it had become the standard choice of construction for many of the larger buildings by the 1930s.[2] However, the domestic cement manufacturing industry was in its nascent stages, and riddled with issues that hindered its growth. The first section in this essay seeks to situate RCC’s rising popularity in India over other building materials, within this context. Simultaneously, the essay asks, why did India opt for RCC while the West gravitated towards steel? 

The following section further argues that ACC and RCC had an almost symbiotic relationship – the company was the primary mover behind the increasing popularity of RCC’s image as a ‘modern’ and ‘revolutionary’ material in India, that ultimately resulted in a permanent alteration of the country’s built landscape. It delves into the formation and growth of ACC, its unique marketing techniques regarding this material, and why the company’s creation affected a significant change in the way India adopted RCC in its architectural language; it also discusses some of the drawbacks that resulted from this historic merger. Apart from reorienting the Indian cement industry, ACC’s innovative and vehement marketing strategies also built a consumer base where none existed before, thus cementing its reputation as a pioneer in advertising techniques in India.

Reinforced Cement Concrete (RCC) – The Modern Material of Possibility

“Ferroconcrete or reinforced cement concrete is a remarkable invention that is revolutionizing architectural design. Shapes entirely undreamt of in earlier materials… are not only possible, they are easy to make..You can support a huge building of ten or fifteen stories on four pillars if you want to, or stretch a railway roof across a dozen rail lines…such a span is hardly possible in any formerly known material.” [3]
                                                     –  Charles Louis Fabri, An introduction to Indian architecture, 1963

Although cement had been in use for nearly 5000 years, Reinforced Cement Concrete or RCC was a modern innovation.[4] Originating in the second half of the nineteenth century, RCC emerged out of a need for a more economical and fireproof building material.[5] 

Other advantages that propelled its popularity included durability, strength, and the ability to expand parts beyond the buildings, for instance, to create cantilevers, a common feature seen in modern architectural styles like Art Deco (see Figure 1).[6] As a 1935 issue of the Indian Concrete Journal proclaimed: “In steel and concrete we have the two greatest structural units the world has known – steel in tension, concrete in compression.”[7]

Why RCC in India?

In India, it can be argued that the increased use of RCC over other materials in the twentieth century was primarily due to the country’s prevailing socio-economic conditions. RCC construction had a large scope for unskilled labour. 

Apart from processes such as the preparation of the steel reinforcements that required supervision, building with RCC claimed to not require any “special skill.”[8] This combined with India’s abundant supply of cheap labour meant that RCC continues to be the standard choice for large-scale projects in the country over other materials, even today.[9]

Large-scale industries of other building materials in modern India (such as steel) were also experiencing growth at a slow rate. Their development was subject to conditions under colonial rule like import-export rules, tariffs, wages, governmental policies and support for domestic production, and the nationalist (swadeshi) struggle.[10] According to British Structural Engineer and expert Stuart Tappin, the UK and USA’s large steel production facilities meant that it was more economical to build larger-framed buildings with steel rather than concrete.[11] The UK was a pioneering force in the invention and production of steel, while in the US, New York’s Art Deco buildings owed their glitz and shine to the new steel alloys, which arrived due to the technological innovations in the early twentieth century.[12] These included non-corrosive stainless steel alloys like nickel silver, monel, duralumin and “Nirosta” ( seen on the glittering crown of the Art Deco Chrysler building); they were replaced post-World War II with newer, less expensive materials that reflected the changing tastes and styles of the post-war generation.[13]

Additionally, the US was regarded as “the nation of steel,” primarily due to the presence of the skyscrapers in New York and Chicago, while Europe was shown to have a preference for reinforced concrete. While not entirely true (American involvement was an important aspect in the development of reinforced concrete around the world), this perception was due to the reluctance of the US to claim this material. The US was not susceptible to the usage of RCC in the twentieth century, due to doubts about whether it could be considered as an “industrial material.”[14] RCC required craft labour which did not correspond with America’s industrial principle of mass production.[15] 

Concrete’s requirement of craft and unskilled labour, along with its perception of traditional or “primitive” origins in mud and clay construction, gave it a complex identity that was neither modern or non-modern. [16]

According to Adrian Forty, concrete is regarded as one of the “new technologies of poverty,” associated with shanty towns and slums in Latin America and Mumbai, a material of ingenuity rather than innovation, which further stigmatised the material in the West.[17] Despite early attempts to equate RCC as a revolutionary modern material in the West, particularly in France, it only briefly displaced steel as the material of modernity.[18]

The post war need for fast and economical construction triggered the need for RCC construction, notes Conservation Architect Vikas Dilwari.[19] While the West went for steel, India’s climate was more conducive to cement which easily replaced lime without changing the rest of the construction technology.[20] A similar case can be made for Miami’s notable Art Deco buildings made of concrete, unlike New York’s skyscrapers which were primarily made of steel. The materials used to create Miami’s Art Deco district were inexpensive due to its origins as a middle-class resort, and also climate-responsive, similar to Mumbai’s Art Deco buildings.[21] They were built in the ‘Tropical Deco’ style, whose features included those adapted to Miami’s environmental conditions (such as a projecting roof plane to shelter the terrace), for which concrete was well-suited. [22]

Despite the plethora of advantages offered by RCC, the Indian cement industry still faced numerous obstacles that prevented it from becoming a large-scale profitable industry. The formation of ACC was proposed as a solution for these issues;  it succeeded in its initiative by combining  the foremost cement companies in an unprecedented merger.

ACC Changes the Game – F E Dinshaw’s Vision and Rationalisation in the Indian Cement Industry

“What set Mr. Dinshaw apart, however, was his commitment to the idea of merger, his powers of persuasion and his drawing force which made things happen.”[23]

                                 – ACC: A Corporate Saga by Abha Chaturvedi, Anil Chaturvedi and M S Kapur

Origin & Objectives of ACC

In India, domestic production of cement had had a rough beginning with the failure of the first cement factory in 1904 due to inadequate raw materials and technological defects. More success was found later with the establishment of the Tata-owned India Cement Company’s factory at Porbandar in 1912.[24] The major locational advantages of this plant included its easy access to limestone quarries (a key ingredient of cement) of Porbandar, and being closer to the Bombay port and the Bengal coalfields.[25] The plant’s success combined with the impetus provided by  World War I (when imports declined and Indian-made cement was more economical than foreign ones) led to further development of the Indian cement industry. 
The increase in demand for cement was also due to its usage as the main construction material, not just for housing, but also for the building of roads, dams, bridges, etc.[26] A section in a 1935 Indian Concrete Journal titled “These figures speak for themselves,” charted the exponential growth in cement consumption, in particular of Indian-made cement – from 945 tons in 1914 to 7,29,319 tons in 1934. Within 20 years, the Indian cement companies had established their reputation as producers of Indian-made Portland cement which was “recognised and appreciated by all Engineers in India.” [27]

However, this promising development was short-lived. Excess supply with inadequate demand, resumption of competition with foreign cement post-World War I, a rate war, and locational disadvantages (both to raw materials as well as markets), led to the liquidation of three factories due to losses. The local cement companies turned to the Tariff Board for protection, which responded by increasing import duties to promote domestic cement. 

Additionally, organisations such as The Concrete Association of India and the Cement Marketing Company of India (established in 1927 and 1930 respectively) were formed to educate the masses about the uses of cement in order to increase demand, and to coordinate prices and marketing of cement, respectively.[28] The Cement Marketing Company of India was responsible for introducing a fixed quota system that managed to stabilise prices, but failed to control production.

It was at this point that eminent Bombay financier, lawyer, industrialist and the founder of ACC, Framroze Edulji Dinshaw (1872-1936), proposed a merger of the cement plants to counter the issues of the quota system.

A shrewd businessman, who was once the holder of the most directorships in the city, Dinshaw recognised the need to capitalise on the popular material of RCC as well as turn it into a profitable industry. [29] 

According to him, the foremost objective of this merger was not to create a “monopolistic” scheme but to provide good quality cement at cheaper rates to the public, against the higher prices of foreign-produced cement, while ensuring a profit margin for Indian cement companies. [30]

This consolidation of Indian cement companies was not only for protection against competition and stabilising of cement prices; according to Dinshaw, it was also to create a unity and cohesion in the companies’ interests as a whole, while providing more advantages than what already existed under the Cement Marketing Company of India to the cement producers, in a more “permanent form.”[31] This was achieved by the amalgamation of manufacturing and sales, centralisation of purchase, pooling of knowledge and resources, and by setting up new factories closer to “consuming centres” for a more economical and efficient system of cement distribution.[32]

Noted businessman Sir Hormasji Pherozshah Mody, the then Chairman of ACC Ltd, stated that ACC was an “outstanding example” of the success achieved through ‘Rationalisation,’ without which it could not have hoped to stabilise the industry. Rationalisation, which began as a movement in 1921, broadly meant the reorganisation of a company to maximise profits, usually entailing the replacement of old machinery with up-to-date ones and release of labour force to increase revenue.[33] 

Mody further wrote that under Rationalisation, ACC took measures to regulate production, prices and marketing, set up an efficient technical service and undertook a “country-wide propaganda” for cement as a building material. Since it was a relatively newer material in the Indian construction industry, this  propaganda was necessary  to make India “cement-minded.”[34]

ACC’s Vigorous Marketing and Propagandising of RCC

ACC was successful in its nation-wide propaganda, significantly transforming the way cement was marketed to the general public. A prominent way it marketed RCC to the public was through print media. For this, it employed the help of organisations such as the Cement Marketing of India, to produce informational booklets, brochures and guides that were disseminated amongst the masses. These included journals and guides that were more technical in nature, intended for architects, engineers and other building industry professionals (such as The Indian Concrete Journal) as well as simpler guides and catalogues for the general public (such as The Modern House in India, 40, 60 and then 80 designs of buildings for every purpose, You can do this!, etc.). 

Written in a simple but informative manner, they showcased the most recent and modern trends in architectural design. It helped that the company had immense control over the Cement Marketing of India and owned a large amount of its shares; it also managed to have an extensive sales network due to this control.[35]

The construction of a new office for the company also became an opportunity to publicise RCC. While the constituent companies’ products were known under their own brand names, there was a need to create ACC’s own identity as a consolidated entity. This involved not just developing a brand name, but also a new office premises.[36] Its new headquarters, ‘Cement House,’ was constructed on Queen’s Road (now Maharshi Marve Marg) opposite Churchgate station, Bombay. Completed in 1943, it is a visually stunning Art Deco structure that flaunted the diverse functionality of RCC; the intricately constructed cantilevered staircase, for example, illustrated the possibilities offered by the construction material in modern design.

Another instance to publicise concrete’s qualities occurred during a 1939 exhibition hosted by the Congress political party. A fire reduced all stalls made of bamboo and thatch (‘swadeshi’ materials that reflected the nationalistic ideology of Congress) to the ground; only the concrete stall made by ACC remained. The company used it as an opportunity to emphasise the durability and functionality of concrete over the more ‘traditional’ and older materials. [38]
During World War II, there was a decrease in building activity; Bombay, one of the larger consumer centres, also saw the introduction of the Urban Immovable Property Tax which affected the consumption of cement. As a result, more emphasis was paid to cement structures that were not buildings, in particular, roads made of cement concrete. Several issues of the Indian Concrete Journal were specifically dedicated to “Road Architecture.” This was also because efficient transportation links comprised an important part of cement production, and was of a major concern to the manufacturers. [39]

By the 1940s, ACC’s reputation as a dominant organisation that shaped Indian construction practices was apparent by the sheer number of significant projects it implemented. Various parts of the lucrative Backbay reclamation region in Bombay for instance, were constructed with  ACC’s cement – from the landmark Marine Drive promenade, to the Art Deco buildings lining them (Figure 8).

ACC’s dominance and contribution towards national development continued well into the post independence period, evidenced by the fact that they supplied 14% of the cement used in construction, nationwide.

ACC also invested in community and infrastructural development around manufacturing locations; this not only saved on transportation costs, but also led to socio-economic development of the regions with the building of houses, schools, etc and the creation of jobs at their production units and related businesses.[40] ACC proclaimed an ideology that reflected the newly independent country’s own – a synthesis of industrial modernity with local needs.[41]

Criticisms & Shortcomings of ACC

However, there were also some setbacks to the merger. Although the architect of the merger F E Dinshaw did not intend on ACC becoming occupying a monopoly position, it inevitably did so. ACC amalgamated 10 of the 12 cement companies at the time; the 10 companies also belonged to 4 eminent Bombay business groups – the Tatas, Khataus, Killick Nixon and the F E Dinshaw groups.[42] The Tatas occupied a significant position in ACC and the cement industry, with the first successful cement company, Indian Cement Co., being owned by them. After the death of F E Dinshaw in 1936, a couple of months before ACC could be formalised, it was up to J.R.D. Tata to pull off the merger. Though the company’s board of directors contained notable businessmen from Western India like Sir Purshottam Thakurdas, Sir Chunilal Mehta and Ambalal Sarabhai, ACC was undoubtedly “Tata-run and Tata-controlled.”[43] ACC exercised immense influence over policies relating to sales and production of cement, and remained virtually unopposed till it was challenged in part by cement companies from Eastern India such as Dalmia Jain cement (est. 1938).[44]

The cartelisation of the cement companies also came at the cost of a loss of autonomy and individual identity of the merged companies.[45]

 Dalmia had refused to join ACC, as it had concluded that there was a discrepancy in the individual companies’ success during the economic depression, with some of the companies doing well, while others experiencing losses; additionally, there was space for more in the industry, and the setting up of a plant was relatively inexpensive.[46] The dangers of cartels, trusts and combines abusing their monopoly and thus sowing “the seeds of Fascism” were recognised in a 1945 issue of the Indian Textile Journal, which also cited the example of anti-trust laws in the US.[47] The process of rationalisation in the industry, which H P Mody had credited in part for the success of ACC, encountered controversies in India’s industries. This included the dilemma of large amounts of labour displacements, particularly in the Indian textile industry, which became a topic for labour protests in India.[48] 

While RCC’s functional qualities were heavily promoted, its shortcomings (such as needing maintenance, or the risk of corrosion, termites, etc.), were either inadequately highlighted or ignored. There were also complaints about the quality of the material, mainly due to the lack of supervision of the processes of the material.[50]

Conclusion

“So far as the A.C.C. is concerned, it may be legitimately claimed that the future is safe in its hands; it has the resources, the men and the technical direction which go to the building up of a great industry.”[51]     

                  – Sir H.P. Mody, Chairman of the Associated Cement Companies Ltd., May 1940

Cement’s meteoric rise in popularity in the early 1900s and its association with Art Deco, signalled the dawn of a modern era in Bombay due to its impact on urban development.[52] A symbiotic relationship developed between ACC and RCC, with ACC’s creation and growth being intricately tied with the development of the modern city and technological innovations like RCC. ACC is often touted as one of the most successful mergers of its time, with a 1936 news article terming it “India’s first important industrial amalgamation.”[53] Its success can be gauged by the multitude of landmark buildings, roads, neighbourhoods, dams, bridges, highways, and other infrastructural elements it built across India including, the Bhakra Nangal dam in Himachal Pradesh in 1960, and the Mumbai-Pune Expressway. 

A look at the formation and development of ACC Ltd is significant due to its contribution in shaping the modern landscape of India. Its creation introduced a new-found confidence in the nascent cement industry at the time, which had previously suffered from price wars in the mid-1920s and dwindling profits, further exacerbated by the economic crisis of the late 1920s. It accomplished the major objectives for which the merger was created, particularly in making the domestic cement industry. Despite the issues that emerged with the rising prominence of this organisation (such as monopolisation), its impact could not be denied.

RCC’s identity as a ‘modern’ material was one of the primary consequences of ACC’s expert marketing and advocacy. By doing so, it also helped shape the modern architectural identity of the country. The brochures, catalogues and guides published by the company, were not only informative, but accessible, covering every part of India, and reaching out to experts and laymen alike. Their investment in infrastructure development went beyond business interests, extending towards the development of local communities and surroundings; community development became a part of their corporate identity.[54] If ACC had not been formed, it would be safe to say the Indian built landscape would have been markedly different.

By the 1950s, the power balance had shifted from Western countries to India and China when it came to cement production. India reportedly also has the most efficient cement plants in the world.[55]

Today, India is the second largest cement manufacturer in the world behind China, with ACC being the second largest cement company in the country.[56] A major reason behind India’s successful position in the global cement industry can be attributed to the creation and efforts of ACC in the past century. 

An unprecedented merger in the twentieth century revived the ailing industry and provided successful alternatives to the way it had functioned till then – it permanently cemented ACC’s position in not only the history of the country’s landscape, but its future as well.
