The invention provides durable recycled concrete and a preparation method thereof, the durable recycled concrete comprises the following components in parts by weight: 1000-1100 parts of recycled coarse aggregate, the particle size of the recycled coarse aggregate is 5-20 mm; 700-800 parts of recycled fine aggregate, wherein the particle size of the recycled fine aggregate is less than 5mm; 250 to 300 parts of cement, wherein the cement is Portland cement; 130 to 160 parts of water; and 1-5 parts of a water reducing agent. By controlling the types of the raw materials for preparing the recycled concrete and the weight ratio of the raw materials and optimizing the preparation method of the recycled concrete, the sulfur and hydrochloric acid corrosion resistance, the impermeability, the compressive strength and the frost resistance of the prepared durable recycled concrete are improved, so that the durability of the recycled concrete is improved.
本申请提供一种耐久再生混凝土及其制备方法，耐久再生混凝土包括以下重量份的组分：再生粗骨料1000‑1100份，所述再生粗骨料粒径为5‑20mm；再生细骨料700‑800份，所述再生细骨料粒径小于5mm；水泥250‑300份，所述水泥为硅酸盐水泥；水130‑160份；减水剂1‑5份。本申请通过控制制备再生混凝土的原材料种类及各原材料的重量比，优化其制备方法，使得制备得到的耐久再生混凝土的抗硫盐酸侵蚀性能、抗渗性能、抗压强度和抗冻性能提高，以提高再生混凝土的耐久性。
