| abstract |
The present invention relates to a cementitious mortar composition comprising 5 to 40% by weight of a quick hardening cementitious cementitious binder, 25 to 65% by weight of a fine aggregate, 10 to 65% by weight of a coarse aggregate, 2 to 25% by weight of water and 0.1 to 5% The hard hardwood cementitious binder is usually 30 to 45% by weight of Portland cement clinker pulverized powder, 30 to 45% by weight of Auwinite quick hard mineral, 10 to 20% by weight of ultra fast cement, 0.1 to 2% by weight of gypsum, 2 to 10% By weight of a latent heat material, and 0.1 to 5% by weight of a latent heat material, and a method of repairing a pavement using the same. According to the present invention, maintenance cost and workability can be improved by solving the high cost of ultra fast cement concrete and by shortening the curing period and improving the durability, compared with ordinary portland cement concrete, crude steel cement concrete and rough steel cement concrete. |
