Abstract:
When soil looses the moisture content below the ground, it is create the volume reduction in the soil and cause the shrinkage cracks on the soil surface. This condition creates moderate to several problematic damage to the Geotechnical Engineering works. Shrinkage of the soil reduced in many ways, but chemical admixture technique is world wide technique to reduce the shrinkage of the soil. In this research paper, using Potassium Carbonate (K2CO3) as a chemical admixture in various proportion such as 0%, 1%, 1.5% and 2% in marine soil to reduce the shrinkage characteristics of the soil. Use of Potassium Carbonate (K2CO3) in marine soil and observed the behaviour of chemical in the soil. Results are concluded that the shrinkage limit is reduced by 32.27% in addition of optimum percentage of chemical.
