Disclosed is a method for producing a road water permeable
brick by using steel
slag. The method is characterized in that the steel
slag which is from
slag fields and are subjected to wheel-style water
quenching and pelletization are subjected to screening, wherein the steel slag larger than 5mm is directly used as aggregate, and the steel slag smaller than 5mm is used as cementing materials; each
raw material is dried until the
moisture content of the
raw material is 0.01%-1%; the steel slag smaller than 5mm is ground into micro powders with 400m <2> / Kg specific surface areas, and then
cement clinkers,
gypsum and slag micro powders are jointly used as the cementing materials for mixing
grinding, wherein the proportion of the cementing materials is 70%-80% of the steel slag aggregate, 10%-20% of the slag micro powders, 5%-10% of the steel slag micro powders, 3%-5% of the
cement clinkers and 2%-5% of the desulfuration
gypsum; and then the steel slag aggregate, the cementing materials and water are stirred according to a water-
cement ratio of 0.25-0.35, the
mixed materials are filled into a mold for mechanical
mashing and pressing, finally molding pressing is performed, and 5 hours of water spraying curing of the steel slag water permeable
brick is performed. The method for producing the road water permeable
brick by using the steel slags has the advantages of being high in steel slag utilization ratio and simple in production process, the quality of the water permeable brick can reach
national standard requirements, and the water permeable brick is difficult to crack.
