Know More

The raw material for cement manufacture is a rock mixture which is about 80 limestone which is rich in CaCO3 and 20 clay or shale a source of silica, alumina and Fe2O3. These are quarried and stored separately. The lime and silica provide the main strength of the cement, while the iron reduces the reaction temperature and gives the cement its

How Concrete Is Made Portland Cement Association
Know More

Cement and water form a paste that coats each particle of stone and sandthe aggregates. Through a chemical reaction called hydration, the cement paste hardens and gains strength. The quality of the paste determines the character of the concrete. The strength of the paste, in turn, depends on the ratio of water to cement.
