Pervious recycled concrete resistant to chloride ion erosion and preparation method thereof
The invention relates to the technical field of concrete, and particularly discloses pervious recycled concrete resistant to chloride ion erosion and a preparation method thereof. The pervious recycled concrete is prepared from the following raw materials in parts by weight: 200-300 parts of cement, 600-700 parts of sand, 1000-1100 parts of gravels, 700-800 parts of recycled aggregate, 80-150 parts of fly ash, 60-100 parts of mineral powder, 70-120 parts of calcium carbonate, 50-100 parts of nanometer silicon dioxide, 40-80 parts of rubber powder, 30-50 parts of steel fibers, 5-7 parts of a tackifier, 3-5 parts of a water reducing agent and 170-230 parts of water. The preparation method comprises the step of uniformly mixing the raw materials to obtain the recycled concrete. By reducing interface action between the recycled aggregate and cement paste, the compactness of an interface transition area is improved, pores in the concrete are reduced, and the chloride ion permeation capacityis reduced, so the chloride ion erosion resistance of the recycled concrete is improved.
本申请涉及混凝土的技术领域，具体公开了一种抗氯离子侵蚀的透水再生混凝土及制备方法。一种抗氯离子侵蚀的透水再生混凝土，由包含以下重量份的原料制成：水泥200‑300份、砂子600‑700份、碎石1000‑1100份、再生骨料700‑800份、粉煤灰80‑150份、矿粉60‑100份、碳酸钙70‑120份、纳米二氧化硅50‑100份、橡胶粉40‑80份、钢纤维30‑50份、增粘剂5‑7份、减水剂3‑5份以及水170‑230份；其制备方法为：将原料混合均匀，得到再生混凝土。本申请通过降低再生骨料与水泥浆之间的界面作用，提高界面过渡区的密实性以及减少混凝土内部的孔隙，降低氯离子渗透的能力，从而提高再生混凝土抗氯离子侵蚀的性能。
