Strength of Soft Clay Reinforced with Group Crushed Polypropylene (PP) Columns

The use of granular columns as soil reinforcement technique has proved useful in problems of foundation stability and settlement, as well as improving soft clay for foundation construction. The purpose of this study is to investigate the enhancement of shear strength of soft kaolin clay when it is r...
