The invention provides a color steel
slag road pavement
brick and a preparation method thereof, and relates to the technical field of production of road pavement bricks. The color steel
slag road pavement
brick comprises a
surface layer and a bottom layer, wherein the
surface layer is prepared from the following raw materials in parts by weight: 17 to 25 parts of
cement, 25 to 30 parts of steel
slag molding sand, 18 to 20 parts of
quartz sand, 5 to 10 parts of
crushed stone, 3 to 6 parts of
volcanic ash, 3 to 5 parts of
zeolite, 3 to 6 parts of
red mud, 4 to 6 parts of mixture, 0.2 to 0.4 part of quick setting agent, 1.3 to 2.3 parts of early strength agent, 0.5 to 1.5 parts of alkaline efforescence-resistant agent, 0.3 to 0.5 part of
pigment powder, 1.2 to 1.6 parts of water
reducing agent and 1 to 3 parts of water; the bottom layer is prepared from the following raw materials in parts by weight: 16 to 25 parts of
cement, 22 to 28 parts of steel slag
molding sand, 19 to 25 parts of
crushed stone, and 2 to 3 parts of water. The preparation method comprises the following steps of weighing the raw materials, manufacturing the
surface layer, manufacturing the bottom layer, forming, demolding, stacking and curing. The color steel slag road pavement
brick and the preparation method can solve the problems of failure to reutilize the wastes, poor water permeability, low
compressive strength, long manufacturing time, whitening, alkaline efforescence discoloring of the surface layer, and the like.
