that will add the soil, cement, and water into the mixer in the specified quantities. If necessary, a screening device shall be used to remove oversized material greater than 2 in (50 mm) from the raw soil feed prior to mixing. Soil and cement shall be mixed sufficiently to prevent cement balls from forming when water is added. The max
The Manufacture of Portland Cement
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 ...
