Abstract：The influence of alkali content and glass powder content on the strength of alkali-activated slag-glass powder cement was analyzed and the strength prediction models were established by using the response surface analysis method of Expert Design software. The results show that the effect of dosage of glass powder on the flexural and compressive strength of cement mortar is not obvious,while the effect of alkali content on strength is great and the interaction of alkali and glass powder has a certain effect on the flexural strength. The results show that when the alkali content is 7%,the glass powder content is 5%,mortar strength is the highest,and the strength of optimal proportion had little difference with the measured values in the laboratory. Therefore,using response surface analysis method can well guide the preparation technology of alkali activated cementitious material to select the optimal mix ratio.
