Cement Stabilization and Clay Soils, with Examples ...

By contrast, clay minerals which possess an expansive lattice, notably montmorillonite, have a significant influence on the hardening of cement. As the range of mineralogy of clay deposits varies enormously, three of the most important components in clay soils, namely, kaolinite, montmorillonite and quartz, were combined to give artificial clay ...

The study involved investigating the performance of ordinary Portland cement (OPC) stabilized soil blocks amended with sugarcane bagasse ash (SBA). Locally available soil was tested for its properties and characterized as clay of medium plasticity. This soil was stabilized using 4% and 10% OPC for manufacture of blocks of size 19 cm × 9 cm × 9 cm.

EFFECT OF ACID RAIN ON LIME AND CEMENT STABILIZED SOILS

The authors used three types of lime and cement stabilized soils, and focused on the physico-chemical and engineering behaviors of the eroded soils. Results obtained show that the pH values of the lime and cement stabilized soils generally decreased with continuous infiltration or soak and that these decreases were greater under a higher acid ...
