Effectiveness of Microbially Induced Calcite Precipitation for Treating Expansive Soils

Expansive soil is a high-plasticity clay that expands rapidly when wetted or soaked with water and shrinks and cracks when it dries. Soil expansion often causes instability problems during construction of roadbeds or embankments. Microbially induced calcite precipitation (MICP), a novel soil treatment method, has drawn increased attention in recent decades because of its environmental friendliness and good performance in soil solidification.
