Compressive Strength of Soil Improved with Cement

The soil type can affect significantly the effect of cement stabilisation. In order to investigate this, five types of soils were mixed with cement at various cement proportions in order to evaluate the large variation of compressive strength values. The compressive strength of the cement treated soils was determined for a curing period of the cement equal to 7 and 28 days. It was obvious that the soil type is a controlling factor on the rate of increase of compressive strength with increasing cement content. Other factors affecting strength are the curing time of cement and the optimum water content.
