Sulphate Resisting Portland Cement (SRC) is a type of Portland cement in which the quantity of tricalcium alumiante is less than 5%. It can be used for purposes wherever Portland Pozzolana Cement, Slag Cement, and Ordinary Portland Cement are used.
The use of Portland Sulphate Resisting Cement has proved beneficial, particularly in conditions where there is a risk of damage to the concrete from sulphate attack. The use of Sulphate Resisting Portland Cement is recommended in places where the concrete is in contact with the soil, ground water, exposed to seacoast, and sea water. In all these conditions, the concrete is exposed to attack from sulphates that are present in excessive amounts, which damage the structure. This is the reason that the use of the Sulphate Resisting Portland Cement have increased in India.
The Sulphate Resisting Portland Cement should be kept in a place which is dry otherwise through premature hydration and carbonation the quality of cement deteriorates. The cement industry in India manufactures Sulphate Resisting Portland Cement in large quantities so that it is able to meet the domestic demand and also export to other countries as well. The Indian cement industry exports cement chiefly to the West Asian countries.
The various uses of Sulphate Resisting Portland Cement are:
- Underground and basements structures
- Works in coastal areas
- Piles and foundations
- Water and sewage treatment plants
- Sugar, chemical, and fertilizers factories
- Petrochemical and food processing industries
The raw materials required for the production of Sulphate Resisting Portland Cement are:
- Coke
- Limestone
- Iron Ore
- Iron Scrap
The major companies manufacturing Sulphate Resisting Portland Cement in India are:
- ACC
- J K Cement
- Indian Cement Ltd
- Grasim Industries
- Gujarat Ambuja
Sulphate Resisting Portland Cement has proved beneficial for construction purposes in India due to its climatic conditions. The cement industry in India must take steps in order to ensure that its quality is improved and to ensure that it is readily available in the market.
The Sulphate Resisting Portland Cement should be stored in a dry place, or else its quality deteriorates due to premature carbonation and hydration. As the Indian cement industry produces Sulphate Resisting Portland Cement in large quantities, it is able to meet the domestic demand and also export to other countries. The cement industry in India exports cement mainly to the West Asian countries.
