The chemical constituents of the brick powder were Al2O3 and SiO2, and the hydration mechanism of the cement was Al2O3 and SiO2. From the chemical position of brick powder and fly ash, fly ash can be used as auxiliary cementitious material, and can be used as Supplementary Cementitious Material in theory. The abandoned red clay bricks as the main raw material of brick powder of different particle size of brick powder with different dosage of replacement of cement cement mortar strength changes, draw the optimum particle size and dosage of, through chemical modification of brick powder instead of cement mortar strength changes. In the same substitution rate and strength of cement mortar with brick powder particle size increases and decreases。 in the same particle size, strength of cement mortar with brick powder instead of rate increases and decreases。 through the lime powder modified can improve mortar early strength。 calcium chloride modified can partially improve the mortar test block strength.
