A HIGH STRENGTH CONCRETE COMPOSITION WITH FIRE RESISTANCE AND CONCRETE USING IT

摘要

PURPOSE: A high-strength refractory concrete composition and concrete produced therefrom are provided to secure the dispersibility of the composition by adding a reinforcing fiber to the concrete. CONSTITUTION: A high-strength refractory concrete composition contains 900-1200kg/m^3 of binder containing cement, 140-170kg/m^3 of water, 400-800kg/m^3 of fine aggregate, 6000-1200kg/m^3 of coarse aggregate, and 0.1-5.0kg/m^3 of thick reinforcing fiber. The reinforcing fiber is coated with a coating solution containing a polyhydric alcohol ester lubricant, a nonionic surfactant, and an antistatic agent.
