Mica stabilization with lime, portland cement and lime-calcium carbonate

Research was conducted to study the unconfined compressive strength of a mica soil stabilized with various percentages of lime, Portland cement, and combinations of calcium hydroxide and calcium carbonate. In order to trace the calcium carbonate and calcium hydroxide in the stabilized soil, x-ray diffraction analyses, differential thermal analysis, and thermagravimetric analyses were made. Results show the appearance of calcium carbonate and absence of calcium hydroxide.
