Durability Improvement of Granite Residual Soil by Lime

DEStech Transactions on Engineering and Technology Research, 2017
Granite residual soil is a kind of common building material for subgrade in China. However, its stability and durability are not as good as requested by specification. Lime is regarded as an effective modifier for granite residual soil. The influence of lime dosages on stability and durability of granite residual soil are evaluated and its ...
