Tamilnadu Cements Corporation Limited (TANCEM) , a wholly owned Government of Tamilnadu undertaking, started business from 1st April 1976 with an authorized share capital of Rs. 18 crores taking over cement plant at Alangulam and setting up another plant at Ariyalur in the year 1979.

TANCEM, as its expansion and conversion activities, set up Asbestos Sheet unit at Alangulam during 1981. TANCEM also took over during 1989, a Stoneware pipe plant from TACEL with a view to provide employment to the retrenched employees.

TANCEM has, thus become a multi plants, multi locations and multi products company with an annual turnover of around Rs. 250 crores and the authorised capital as of now is Rs. 37.43 Crores.

The company has its main objective in production of cement and cement based products and primarily cater to the needs of Government departments. Limestone being the main raw material, the company acquired and reserved enough limestone bearing lands in and around Alangulam and Ariyalur which are sufficient to run the cement plants for decades to come. Hence, the role of TANCEM in the development of state is immense.
