Determination of optimum concentration of lime slurry for soil stabilisation

Lime has been used as active additive in soil stabilisation for the past 5000 years ago. The Pyramids of Shersi in Tibet were built using compacted mixtures of clay and lime. Lime powder is normally spread on the ground using mechanical means before mixing with the soil. The problem arise from lime...
