Water permeable brick prepared by using natural zeolite and steel slags as raw materials

The invention belongs to the field of brick making, and relates to a water permeable brick prepared by using natural zeolite and steel slags as raw materials. Raw materials comprise a binding material, an aggregate, a modifying agent and water, and the water is used as a dispersing agent. The binding material is fine-ground steel slags and cement, the aggregate is natural zeolite and grit, and themodifying agent is one or more of sodium tartrate, sodium malate and sodium citrate. In the brick making process, the shaping pressure is 18-25MPa, after the brick is shaped, steam curing needs to beperformed, the curing temperature is 45-75 DEG C, and the curing time is 12-72h. The steel slags are used for preparing the water permeable brick, and through combination of a physical method and a chemical method, before preparation and during preparation, the steel slags are modified, and the volume invariability of the finished product namely the brick is improved. 本发明属于制砖领域，一种以天然沸石和钢渣为原料制备的透水砖，原料由粘结料、骨料、改性剂、水构成，以水作为分散
