The clayey soils of Kameyama Mountain in Mie prefecture were studied experimentally in the laboratory with the idea of improving some of its engineering properties by using a very small amount of ordinary Portland cement. Laboratory tests on shear strength, compressive strength, consistency limits, compaction and specific gravity of soil were carried out with cement content of 0%, 0.2%, 0.4% and 0.6% by weight. It was observed that the cohesion which is a major component regarding the strength of soil was increased with the increase in the amount of cement and angle of internal friction at higher cement content was decreased. Compressive tests under two different room temperatures showed the compressive strength to be increased with the increase in the quantity of cement depending upon the temperature providing on it. Plasticity index, a measure of soil plasticity was found to decrease with the increase in the percentage of cement mixed with it. A close observation of results plotted in the plasticity chart also noticed that the addition of cement reduced the compressibility, dry strength and toughness of soil whilst increasing the volume change ratio and specific gravity of soil.
