Recycled concrete and production process thereof
The invention relates to the technical field of concrete manufacturing, and particularly discloses recycled concrete and a production process thereof. The recycled concrete is prepared from the following components in parts by weight: 350-450 parts of recycled coarse aggregate, 180-250 parts of cement, 250-300 parts of fine aggregate, 85-110 parts of water, 15-30 parts of closed cell perlite, 20-38 parts of hydroxy propyl cellulose and 2-5 parts of water reducing agent. The preparation method comprises the following steps: preparing the recycled coarse aggregate: crushing the waste concrete waste, washing with water, removing dust on the surface of the crushed waste concrete waste, and drying to prepare the recycled coarse aggregate for later use; and preparation of the recycled concrete: dissolving hydroxy propyl cellulose in water to prepare a hydroxy propyl cellulose aqueous solution, and stirring the recycled coarse aggregate, the fine aggregate, the closed cell perlite, the water reducing agent, the cement and the hydroxy propyl cellulose aqueous solution together to prepare the recycled concrete. The recycled concrete provided by the invention has the advantages of relatively good compressive strength and water seepage resistance.
本申请涉及混凝土制造的技术领域，具体公开了一种再生混凝土及其生产工艺。再生混凝土包含以下重量份的组分：再生粗骨料350‑450份，水泥180‑250份，细集料250‑300份，水85‑110份，闭孔珍珠岩15‑30份，羟丙基纤维素20‑38份，减水剂2‑5份；其制备方法包括再生粗集料制备：废弃混凝土废料进行破碎，并用水进行冲洗，除去破碎后废弃混凝土废料表面的灰尘，干燥制得再生粗集料备用；再生混凝土制备：将羟丙基纤维素溶于水制成羟丙基纤维素水溶液后，将再生粗集料、细集料、闭孔珍珠岩、减水剂、水泥和羟丙基纤维素水溶液一同搅拌，制成再生混凝土。本申请的再生混凝土，其具有相对较佳的抗压强度和抗渗水能力优点。
