As a new type of dam materials,the mechanical properties of CSG material are significantly affected by cement content,fly ashcontent,water binder ratio,sand ratio,aggregate gradation and age factors. In order to explore the influences of various factors on thecompressive strength of the material,through a lot of experiments,this paper studied the variation laws of compressive strength and watercement ratio,sand ratio,cement content,fly ash content and other factors. When the engineering common sand ratio is in the range of0.1-0.4,the optimal sand ratio is 0.2,corresponding to the optimal water binder ratio between 1.4 and 1.0. When the sand ratio is high,theupper bound of the optimal water binder ratio should be taken,and the lower value of the optimal water binder ratio is taken when the sandratio is low. When the optimal sand ratio is 20%,the optimal water binder ratio is about 1.1. In every cubic meter of CSG materials,cementcontent increases by 10 kg,the 28 d compressive strength of the cube can increase by 15%-20%. With the increase of fly ash content per 10 kg,the compressive strength of cubic 28 d is increased,and the increase range is between 10% and 1%. The effects of specimen size andaggregate gradation on the compressive strength of the material are significant.
