Manufacturing method of steel slag perforated brick
The invention relates to the technical field of gold solid waste recovery treatment, and particularly discloses a steel slag perforated brick manufacturing method which comprises the following steps: step 1, pouring a rubber material, water and a water reducing agent into a stirring barrel according to a ratio, and fully stirring until the surface of cement paste has metallic luster; 2, adding the aggregate accounting for 40-60% of the total amount for the first time, fully stirring, adding the remaining aggregate for the second time, and continuously stirring until the cement paste uniformly wraps the surface of the aggregate and forms a cement paste shell on the surface of the aggregate; 3, pouring the mixed slurry into a mold in multiple layers, removing redundant loose materials on the surface, and compacting; 4, curing at room temperature after mold filling and forming, covering with plastic paper to reduce water loss, spraying a proper amount of water every 5.5-6.5 h to ensure the humidity of the brick body, and removing the mold after 1 d; and step 5, after the mold is removed, standing for 28 days at room temperature to obtain the final porous brick. The invention aims to solve the problems that the existing steel slag solid waste is difficult to treat, is easy to crack after being applied to building materials for a long time and has potential safety hazards.
本申请涉及金固体废物回收处理技术领域，具体公开了一种钢渣多孔砖制作方法，包括以下步骤：步骤一：将胶材、水和减水剂按配比倒进搅拌筒，充分搅拌直到水泥浆表面出现金属光泽；步骤二：第一次加入占总量40％‑60％的骨料，充分搅拌，第二次加入剩余骨料，继续搅拌，直到水泥浆均匀包裹在骨料表面，在骨料表面形成水泥浆壳；步骤三：拌合好的浆料分多层倒入模具，剔除表面多余松散物料后压实；步骤四：装模成型后在室温下养护，用塑料纸覆盖，减少水分散失，每5.5‑6.5h适量喷水处理，保证砖体湿度，1d后拆模；步骤五：拆模后室温下静养28d得到最终多孔砖。本专利的目的在于解决现有钢渣固废处理难，应用至建筑材料长期使用易开裂，存在安全隐患的问题。
