The results indicate that cement mixing ratio, water content and comparative effort have important influence on shear strength, compressibility and microstructure of the compacted cement -loess.
By controlling the range of the dry density, magnitude of cement and watercementratio of mixture, the requirement of drainage property and structure strength can be fulfilled.
通过控制混合料的干密度、水泥用量和水灰比的取值范围，可使混合料同时满足排水性能要求和结构强度要求。

The essence of concrete framework theory is to deduce the cement dosage of unit volume concrete from frame-mortar ratio, unit water dosage and deviated function of cement-sand ratio.
