Birth Of The Ramco Cements Limited : In the 1950s, investment in Cement Industry was not attractive due to price controls and the massive investments required. Only those entrepreneurs who were not profit-minded but cared for the country's development came forward to invest in the Cement Industry.

Birth of Cement Plants :  The first plant of RCL at Ramasamy Raja Nagar, near Virudhunagar in Tamil Nadu, commenced its production in 1962 with a capacity of 200 tonnes, using wet process. In 70s, the plant switched over to more efficient dry process. A second kiln was also added to bring the total capacity to 15 lakh tons per annum.
The second venture of RCL is its Jayanthipuram plant near Vijayawada in A.P., set up in 1987. The 36.50 lakh ton per annum plant employs the latest state-of-the-art technology.
The third venture of RCL is at Alathiyur in TN. It was set up in 1997 and expanded by addition of another line in 2001. The 30.50 lakh tons per annum plant is the most modern plant in the country.
Ariyalur plant started operations in 2009 with a capacity of 2 MTPA. It is well-equipped with modern quality control systems.Currently Line 2 of the plant with a capacity of another 2 MTPA was commissioned in 2012.

When Shri. Manubai Shah, Central Minister for Industries in late fifties came to Madras to meet the Industrialists, he called upon Shri P A C Ramasamy Raja and requested him to start a cement factory in TN. This was readily accepted by Shri PACR and this marked the birth of The Ramco Cements Limited in 1961.
