CONCRETE COMPOSITION FOR PAVEMENT OF BRIDGE AND CONSTRUCTION METHOD USING THE SAME

摘要

A concrete composition for the bridge-deck paving and a bridge-deck paving method using the same are provided to secure the excellent resistivity to the penetration of the water by the fatty acid metal salt component. A concrete composition for the bridge-deck paving comprises followings. The mortar composition for impregnation is applied in the cleaned bridge deck. The concrete composition for the bridge-deck paving is applied in the surface in which the mortar composition for impregnation is poured. The concrete composition for the bridge-deck paving comprises: cement 100 weight%; high pulverization word slag 10~40 weight%; fly ash 8~15 weight%; absorption inhibitor 0.1~1 weight%; dispersing agent 0.5~2.0 weight%; air entraining agent 0.0001~0.0004 weight%; and nylon fiber reinforcing material 0.02~0.05 weight%. The mortar composition for impregnation is made of: cement 100 weight%; calcium alumino sulfate 14~22 weight%; anhydrous gypsum 10~16 weight%; and synthetic rubber latex 55~70 weight%.
