CEMENT STABILIZATION AND CLAY SOILS, WITH EXAMPLES

Clay soils often present difficulties in construction operations, although their engineering properties can be enhanced by the addition of small percentages, by weight, of cement. This produces an improved construction material that can be used for construction purposes. Nonetheless, the properties of the soil-cement are affected by the type of minerals present in deposits of clay. Kaolinite appears to have little effect on the hydration process and hardening proceeds normally. 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 soils in which one mineral type was dominant. In this way, the influence of these minerals on cement stabilization could be assessed. The engineering properties of such 'soils' were assessed and compared with the same properties when the 'soils' were treated with small amounts of cement.
