CONCRETE BINDER COMPOSITION FOR REINFORED LAITANCE

摘要

PURPOSE: A concrete binder composition for reinforcing laitance is reduce the generation of cracks and moisture penetration by improving the reactivity of the composition with respect to laitance. CONSTITUTION: A concrete binder composition for reinforcing laitance includes 45-49.9 weight% of nano slag powder, 45-49.9 weight% of an alkaline stimulator, and 0.1-10 weight% of water. The fineness of the nano slag powder is more than or equal to 30,000cm^2/g. The alkaline stimulator is one or more selected from calcium hydroxide, potassium hydroxide, calcium silicate, and sodium carbonate. The content ratio of the nano slag powder and the alkaline stimulator is 1:1.
