Fast hardening, early light loading and surface cracking resistance concrete
The invention relates to fast hardening, early light loading and surface cracking resistance concrete, which is mixed with water to maintain good workability, develop early strength and high end strength (R-28). Material composition of concrete according to the invention is as follows: Item Percent (%) River Sand 20-25% Crush Sand 12-16% Stone 5 x 10 40-50% Cement OPC 18-22% High alumina cement 1.5-2% Fiber 0.01-1% Powercon 100 0.01-1% Lithium Carbonate 0.01-1% Sodium Gluconate 0.01-1% Esapor 1850-C 0.01-1% Other additives 0.01-1%
