Lime Vs Cement: Which Soil Stabilization Method is Better ...

2021-4-23 · Soil cement stabilization is a construction technique used to increase the strength of subgrade soil by mixing it with cement and water. The water hydrates the cement, generating reactions that create a matrix between the soil particles and gives the soil strength. Cement stabilization is especially useful in coarse-grained soils.
