POLYMER ADMIXTURE MODIFIED RAPID SETTING CONCRETE COMPOSITE AND METHOD FOR REPARING AND REINFORCING CONCRETE STRUCTURES ROAD PAVEMENT USING THE SAME

摘要

The present invention provides a polymer admixture-modified fast-hardening concrete composition comprising a fast-hardening binder, a polymer admixture, aggregate and water, wherein the fast-hardening binder comprises 30 to 55 wt% of calcium sulfoaluminate clinker relative to the total weight of the quick-hardening binder, calcium alumina 10 to 20% by weight of nate clinker, 10 to 35% by weight of portland cement, 10 to 35% by weight of anhydrite, 5 to 15% by weight of slaked lime, and 10 to 20% by weight of silica fume, wherein the polymer admixture comprises the entire polymer admixture. Polymer admixture-modified fast-hardening concrete composition comprising 65 to 90% by weight of SBR (Styrene-Butadiene Latex) polymer and 10 to 35% by weight of polycarboxylic acid-based dispersion and maintenance agent, and road pavement repair using the same It provides a method of reinforcement.
