시멘트 混合土의 壓縮强度에 關한 硏究 = A Study on the Unconfined Compressive Strength of Soil-Cement Mixture

다국어 초록 (Multilingual Abstract)

This study was conducted to obtain the most effective distribution of grain size and the optimum cement content for cement-soil stabilization. To achieve the aim, the unconfined compressive strength was tested by adding 4, 6, 8, 10 and 12 percent by weight for all soils adjusted by given ratios of sand to clay.
The results obtained were as follows:
1. Although the rate of strength increase varied with cement conent, the more cement content of cement-soil mixture, the larger unconfined compressive strength of cement-soil mixture. The optimum cement content ranged between 4 and 10 percent by weight for all soils by adjusting ratios of sand to clay.
2. The optimum cement content of cement-soil mixture was obtained in the soil, having the ratio of about 40 percent of cohesive clay and about 60 percent of sand by weight.
3. the unconfined compressive strength of cement-soil mixture was great in the soil with less amount of clay in the course of curing time.
