Control factors of grouting soil

Grouting soil stirring for foundation improvement is one of techniques of foundation treatment.The intensity of consolidated mixture of cement and soil is controlled by water content,the volume of blended cement and the kinds of subsoil.The laboratory and in situ experiment results show that the water content influences the intensity of grouting soil negatively;the relationship between intensity of grouting soil and the volume of blended cement is not simple positive correlation,and the influence of soil kinds is relatively larger.The intensity of sludge and mud is lower,because of their large content of organic matter,but the intensity of grouting soil formed by silt and clay is larger.
