MORTAR COMPOSITION FOR IMPREGNANT OF BRIDGE AND PAVEMENT CONSTRUCTION METHOD USING THE SAME

摘要

A mortar composition for impregnating bridge deck is provided to improve a resistivity to melting agent like calcium chloride due to integrity knuckle of blast furnace slag particle and to improve water-tightness and surface finishing property by fly ash admixture. A mortar composition for impregnating bridge deck includes calcium alumino sulfate 14~22 parts by weight, cement part 100 parts by weight, anhydrous gypsum 10~16 parts by weight, synthetic rubber latex 55~70 parts by weight, sand 120~170 parts by weight of which maximum grain size is 3mm or less and a retarder 0.01~0.03 parts by weight.
