MORTAR COMPOSITION FOR REPARING AND REINFORCING CONCREATE STRUCTURE COMPRING OF RAPID CURING BINDER USING INDUSTRIAL BY-PRODUCTS AND USING THIS CONCRETE STRUCTURE REPARING AND REINFORCING METHODS

摘要

PURPOSE: A mortar composition comprising a rapid curing binder based on industrial by-products for repairing and reinforcing the cross section of a concrete structure and a method for repairing and reinforcing the cross section of the concrete structure using the same are provided to improve the adhesive to base concrete and to rapidly obtain the required strength of the composition. CONSTITUTION: A rapid curing binder includes 100 parts by weight of Portland cement, 5-30 parts by weight of waste glass powder, 10-40 parts by weight of blast furnace slag powder, 30-55 parts by weight of one or the mixture of anhydrous phosphogypsum and anhydrous fluorogypsum, and 1-10 parts by weight of alkali activator. The alkali activator is based on one or the mixture of the hydroxide, the chloride, the sulfur oxide, the carbon oxide of alkali metals.
