Method for preparing concrete from waste bricks and tiles
The invention relates to a method for preparing concrete by using waste bricks and tiles, and belongs to the field of building materials. The method comprises the following steps of: crushing the waste bricks and tiles, mixing raw materials, and preparing a composite enhancer which is prepared by mixing aluminum sulfate, ferric aluminum silicate, ammonium phosphate, magnesium sulfate and redispersible latex powder; and mixing the mixed raw materials with the composite enhancer, then mixing sand, stone and water, and carrying out concrete casting. According to the invention, the waste bricks and tiles are effectively utilized, and the cast concrete has the characteristics of high strength, high hardening speed, no cracking and firm bonding with a base building.
本发明涉及一种用废弃砖瓦制备混凝土的方法，属于建筑材料领域，本发明包括废砖瓦粉碎、原料混合、复合强化剂制备，其中复合强化剂用硫酸铝、硅酸铝铁、磷酸铵、硫酸镁、再分散乳胶粉混合制成，将混合原料和复合强化剂混合后混合砂、石和水进行混凝土浇铸。本发明不仅有效利用了废砖瓦，且在浇铸后的混凝土具有强度大、硬化速度快、不开裂且与基层建筑粘结牢固的特点。
