With the strength determination of the Composite Cementitious Mortar,the effects of different types of cements and proportions of the composite cementitious materials on the strength performance of the cement mortar containing ground slag and fly ash are analyzed.The experiments proved that the relationship between the strength of the cement based composite cementitious materials and the activity index of the mineral admixture is not a simple linear one,while as the composite mineral admixtures have better performances than that of a single admixture because of "induced activation" effect,which shows the advantage of effect superposition and the different proportions of the composite mineral admixture have an apparent effect on the strength of the composite cementitious mortar,while at the same time there is an optimal mix proportion.
