Effect of Soft Clay Bearing Capacity on Cement-Lime Stabilization

Abstract

Soil stabilization is the process by which a soil physical property is transformed to improve the geotechnical properties of the soil as well as the strength of the soil especially for the construction of subgrade for soft clay. The nature of soil strength is dependent on the characteristics of shear strength, bearing capacity as well as capacity in the strengthening process. Therefore, this study was conducted for the effect of soft clay, bearing capacity on cement-lime stabilization by performing a California Bearing Capacity (CBR) test with curing periods of 4 days, 7 days, 21 days, and 28 days. The study was conducted with a mixing ratio of 3% cement and 4% lime with an addition of 4% cement-lime according to the weight of the soil sample. The test was carried out by laboratory tests and mathematical descriptive. As a result, the CBR value increased by 1.5 to 3.90 to 7 days of curing and increased by 16.82 from the CBR value of 3.0 to 28 days of curing period at a 4% cement-lime mixture ratio. This increase gives a difference of up to 460% of the control sample. Thus, the cement-lime stabilization against soft clay achieves a significant increase in soil bearing capacity.
