Method for improving carbonization resistance of alkali slag concrete
A method for improving the carbonization resistance of alkali slag concrete is characterized in that Zn(OH)2, ZnCl2, and an air entraining agent or dihydrate gypsum is blended in the preparation process of alkali slag concrete, blended Zn(OH)2 and ZnCl2 can improve the alkalinity of the solid dispersion phase of the alkali slag concrete, and the air entraining agent and the hihydrate gypsum can improve the compactness and the pore structure of the alkali slag concrete, so the carbonization degree of the alkali slag concrete is reduced, and the carbonization resistance of the alkali slag concrete is improved. The 3d carbonization degree of the alkali slag concrete is 50-60% lower than that of base alkali slag concrete, the 28d carbonization degree of the alkali slag concrete is 20-30% lower than that of the base alkali slag concrete, and the mechanical performances of the alkali slag concrete are not negatively influenced.
