Determination of Plasticity Index and Compression Index of Soil at Perlis

Abstract

This research has been conducted as an initiative to determine Plasticity Index (PI) and Compression Index (Cc) of soil samples taken at several locations around Perlis. For each location, the disturbed soils samples are taken at three different points and are indicated by P1, P2 and P3. In addition, Particle Size Distribution, Specific Gravity and pH test is also conducted to obtain more detailed information for the soil samples. Preparation of soil sample and the experimental procedure is based on BS1377 (1990). The results of this study have shown that, when the value of Plasticity Index (PI) increases, the Compression Index (Cc) will also be increased. From this research, relationship between Plasticity Index (PI) and Compression Index (Cc) is established. The Compression Index (Cc) of soil sample can be identified by executing the Plasticity Index (PI).
