Abstract：The mechanical properties of mineral admixtures at different temperatures were studied by using the pozzolanic ra-tio strength analysis method,and the evolution trend of pozzolanic effect of mineral admixtures at different ages under 10℃ was analyzed. The results show that the addition of composite mineral admixture enhances the strength of mortar,and low temperature affects the volcanic effect of mineral admixture. The volcanic ash effect of mineral admixture at 10℃ is lower than 20℃,and the volcanic ash effect of composite mineral admixture at the same temperature with the age trend is basically the same. At 10℃,im-proving the silica fume content can better play volcanic ash effect of the complex mineral admixture.
