The advantages of cement
CSA cement is considered to be a green binder because of the following factors: 1. CSA cement is calcined at 1250oC (2250oF) whereas Portland is calcined at a temperature of 1500oC (2700oC). 2. CSA clinker is much softer compared to Portland clinker, which reduces the energy requirement during grinding.

SoilCement
Soilcement thicknesses are less than those required for granular bases carrying the same traffic over the same subgrade. This is because soilcement is a cemented, rigid material that distributes loads over broad areas. Its slablike characteristics and beam strength are unmatched by granular bases. Hard, rigid soilcement resists cyclic cold, rain, and springthaw damage. Old soilcement ...
