▎ 摘　　要

NOVELTY - A concrete surface reinforcing agent comprises component (A) comprising aqueous solution comprising fluorosilicate, hydrated calcium silicate gel powder, graphene dispersion, cellulose ether and polycarboxylic acid water reducer, and component (B) comprising modified nanosilica sol and curing agent. USE - Concrete surface reinforcing agent. ADVANTAGE - The reinforcing agent uses graphene which has excellent mechanical properties thereby improving the microporous filling and sealing effect on the concrete surface, and effectively improves the volume stability of the hydration product formed in the micropores of the concrete surface, and improves the mechanical properties and bonding properties of the interface between the microporous walls of the concrete, thus improving reinforcement of the concrete surface. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for usage method of the concrete surface reinforcing agent.
