Cement Stabilisation

The use of cement is a critical aspect for an economic advantage. A lower content of cement will give a substantial reduction of the costs. The cement content in the soil-cement stabilization is 4 to 6% more than in a regular sand-cement stabilization. In case of a small batch of polluted soil the costs of environmental and physico-mechanal ...
