The composition of repair and strengthening mortars and concrete with high workability and adhesion for section jacketing method of reinforced concrete structures

摘要

Disclosed is a mortar composition for repair and reinforcing by improving durability, such as adhesion, water tightness, dry shrinkage, and chemical resistance, and improving workability by high flow by incorporating superfast cement and polymer resin in a specific content. The present invention is a mortar composition for repair and reinforcement of a concrete structure manufactured using a binder comprising 70 to 85% by weight of Portland cement, 5 to 15% by weight super cement, and 10 to 15% by weight of EVA-based re-emulsifying polymer resin. to provide.
