Corrosion-resistant recycled concrete and production process thereof
The invention relates to the technical field of concrete, and particularly discloses a corrosion-resistant recycled concrete and a production process thereof. The corrosion-resistant recycled concrete is prepared from, by weight, 250 to 300 parts of cement, 600 to 650 parts of sand, 920 to 980 parts of stones, 580 to 630 parts of recycled aggregate, 60 to 70 parts of fly ash, 30 to 40 parts of nano calcium carbonate, 25 to 35 parts of nano silicon dioxide, 20 to 30 parts of reinforced fibers, 8 to 12 parts of a tackifier, 6 to 8 parts of a water reducing agent and 170 to 210 parts of water. The preparation method comprises the step of uniformly stirring the raw materials. As the recycled aggregate is adopted in the recycled concrete system, on one hand, the generation cost of the concrete can be reduced, on the other hand, the recycling of the waste concrete is realized, and the prepared recycled concrete has excellent corrosion resistance.
本申请涉及混凝土的技术领域，具体公开了一种耐腐蚀再生混凝土及其生产工艺。一种耐腐蚀再生混凝土由包含以下重量份的原料制成：水泥250‑300份、砂子600‑650份、石子920‑980份、再生骨料580‑630份、粉煤灰60‑70份、纳米碳酸钙30‑40份、纳米二氧化硅25‑35份、增强纤维20‑30份、增粘剂8‑12份、减水剂6‑8份以及水170‑210份；其制备方法为：将各原料均匀搅拌即得。本申请由于在再生混凝土体系中采用再生骨料，一方面能够降低混凝土的生成成本，另一方面实现废旧混凝土的再利用，且制备的再生混凝土具有优异的耐腐蚀性能。
