Abstract: Through the strength test and hydration heat test of cement mortar , to observe the hydration morphology and characteristics of cement .which is corrosion resistance, fly ash and slag powder according the SEM and XRD.The test results show that: It is beneficial to improve the compressive strength of cement mortar and reduce the hydration rate of cement by adding corrosion inhibitor and double mineral admixture, but the latter reduces the early strength of mortar due to slow hydration ; After the combination of the three, it further reduces the early hydration heat release rate of cement , avoids the concentrated exothermic of the cementitious material hydration , so that the 56 d compressive strength of the rubber sand is higher than the reference group 8 MPa.The structure morphology of SEM and XRD diffraction spectra showed: The alkali modification of mineral admixture has been realized by adding the anticorrosion rust-inhibiting ingredient, which promotes the two times hydration of mineral admixture and enhances the strength and durability of mortar or concrete .
