【Abstract】 Reasons of low strengths and low the freezeproof of lime stabilized specific silt and adding cement for lime stabilized silt to produce shrinkage crack are analysed.The problem which the strengths and the freezegroof of lime stabilized silt are increased by adding 0.75% water glass or 0.3% pure alkali are investigated.更多还原
