Preparation method of recycled aggregate foamed concrete
The invention discloses a preparation method of recycled aggregate foamed concrete. The recycled aggregate foamed concrete is prepared from the following raw materials in parts by weight: 80-100 parts of aggregate, 40-55 parts of cement, 30-45 parts of water, 15-30 parts of a foaming agent, 5-8 parts of a foam stabilizer, 7-9 parts of mineral powder and 7-10 parts of a water reducing agent, and the recycled aggregate is shaped waste concrete particles; the preparation method of the recycled aggregate foamed concrete comprises the following steps: 1, cleaning waste concrete, cutting reinforcing steel bars, removing the reinforcing steel bars and various impurities, crushing into an aggregate blank with the diameter of 8-12mm through a crusher, and shaping the aggregate blank in a stone shaping machine to obtain an aggregate; the waste concrete is used for preparing the recycled aggregate, then the recycled aggregate foamed concrete is prepared from the aggregate, consumption of natural aggregate in the building industry can be reduced, the problems of increasingly deteriorated ecological environment and the like caused by concrete waste can be solved, and the preparation method is relatively simple and easy to operate.
本发明公开了一种再生骨料发泡混凝土的制备方法，再生骨料发泡混凝土由以下重量的原料制成：骨料80‑100份、水泥40‑55份、水30‑45份、发泡剂15‑30份、稳泡剂5‑8份、矿粉7‑9份、减水剂7‑10份，再生骨料为整形后的废弃混凝土颗粒；再生骨料发泡混凝土的制备步骤包括：步骤一：把废弃混凝土清理干净后，进行钢筋切割，除去钢筋和各种杂质，再通过破碎机进行粉碎，粉碎成直径为8‑12mm的骨料毛坯，然后在把骨料毛坯放入到石料整形机进行整形得到骨料；本发明利用废弃混凝土制备再生骨料，在通过骨料制备再生骨料发泡混凝土，不仅可以减少建筑业对天然骨料的消耗，还可以减轻混凝土废弃物造成的生态环境日益恶化等问题，本发明制备方法比较简单，易操作。
