Equations controlling compressive strength ratio of soft Bangkok clay stabilize with cement under unconfined compression test.

Abstract

This paper is to study and develop an equations controlling compressive strength ratio under only unconfined compression strength of soft Bangkok clay stabilized with cement. The mix ratio of soft clay blended with cement is shown in term of the cement/clay-water ratio (C/w_c) which are 0.2, 0.3, and 0.4. Liquidity index are 1.0, 1.3, and 1.6. The law materials consist of soft Bangkok clay and ordinary Portland cement type 1. The equations controlling compressive strength ratio can be explained the strength and stiffness of soil-cement mixtures with high water content. Finally, the equations controlling compressive strength ratio is shown in term of the cement/clay-water ratio (C/w_c) and the porosity/cement ratio (η/C_iv) for predicting the compression strength of soft Bangkok clay stabilized with cement.
