High-strength recycled concrete and preparation method thereof
The invention relates to the technical field of concrete preparation, and particularly discloses high-strength recycled concrete and a preparation method thereof. The high-strength recycled concrete comprises the following components: cement, mineral powder, fly ash, natural sand, recycled coarse aggregate, polypropylene glycol, sodium bicarbonate, dolomite powder, diethanolamide, a diatomite, a water reducing agent and water. The preparation method comprises the following steps: step 1, mixing the cement, the mineral powder, the fly ash, the natural sand, the recycled coarse aggregate, the dolomite powder, the sodium bicarbonate and the water in corresponding parts by weight, and uniformly stirring the components to obtain premixed concrete; and 2, mixing the diethanolamide, the dolomite powder, the water reducing agent and the premixed concrete in corresponding parts by weight, and uniformly stirring the components to obtain the high-strength recycled concrete. The high-strength recycled concrete can be used for building and bridge pavement construction, and has the advantages of high compressive strength and stable working performance.
本申请涉及混凝土制备的技术领域，具体公开了一种高强再生混凝土及其制备方法。高强再生混凝土包括如下的组分：水泥、矿粉、粉煤灰、天然砂、再生粗骨料、聚丙二醇、碳酸氢钠、白云岩粉、二乙醇酰胺、硅藻土、减水剂和水；其制备方法为：步骤一，将相应重量份数的水泥、矿粉、粉煤灰、天然砂、再生粗骨料、白云岩粉、碳酸氢钠和水混合，搅拌均匀得到预拌混凝土；步骤二，将相应重量份数的二乙醇酰胺、白云岩粉、减水剂和预拌混凝土混合，搅拌均匀得到高强再生混凝土。本申请的高强再生混凝土可用于建筑、桥梁路面施工使用，其具有抗压强度高、工作性能稳定的优点。
