▎ 摘　　要

NOVELTY - Auxiliary cementing material, comprises 40-60 pts. wt. reference cement, 5-10 pts. wt. potassium dihydrogen phosphate, 5-10 pts. wt. magnesium sand, 0.5-1 pt. wt. borax, 2 pts. wt. gypsum, 10-20 pts. wt. metakaolin, 2-6 pts. wt. activator, 0.2-2 pts. wt. dispersant and 1-10 pts. wt. nano filler. USE - Auxiliary cementing material with high resistance to chloride ion erosion. ADVANTAGE - The auxiliary cementing material reduces the free chloride ion content in the concrete, enhances the chloride ion resistance and reduces the corrosion damage of steel bars. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation method of auxiliary cementing material.
