| description | The invention belongs to the technical field of steel slag building material resource utilization and carbon capture, and particularly relates to a steel slag-based water permeable brick cured by using CO2 through a hydration-carbonization coupling system and a preparation process of the steel slag-based water permeable brick. The preparation method comprises the following steps: uniformly mixing coarse aggregate and water according to a proper liquid-solid ratio, adding a gelling material, water and a carbon sequestration reinforcing agent, uniformly stirring, pouring into a mold for compression molding, curing for 4-10 hours under the conditions that the temperature is 20-25 DEG C and the relative humidity is about 95%, and demolding to obtain a semi-finished product of the steel slag water-permeable brick; and curing for 12-18 hours under the condition that the relative humidity is less than 75%, and carbonizing and curing for 2-8 hours in a carbonization reaction kettle to obtain the steel slag-based carb |
