Green and environment-friendly concrete and construction technology thereof
The invention relates to the technical field of concrete, and discloses green and environment-friendly concrete, which is prepared from the following raw materials in parts by weight: 8 to 20 percent of cement, 25 to 50 percent of recycled concrete aggregate, 0.3 to 1 percent of water glass, 1 to 3.5 percent of sodium hydroxide, 8 to 12 percent of fly ash, 6 to 15 percent of coal gangue and the balance of water; the second raw materials comprise, by weight, 8%-20% of cement, 25%-50% of rubber particles, 0.3%-1% of water glass, 1%-3.5% of sodium hydroxide, 8%-12% of fly ash, 6%-15% of coal gangue and the balance water. According to the green and environment-friendly concrete, the recycled concrete aggregate, the rubber particles, the fly ash, the coal gangue and other components in the raw materials are all prepared from industrial wastes, compared with traditional concrete raw materials, CO2 emission during concrete production is greatly reduced, the recycled concrete aggregate is subjected to special treatment and then replaces river sand and pebbles to be mixed with cement to prepare the recycled concrete, and the environment-friendly effect is achieved. The method is used for reconstruction of new buildings and solves the problem of treatment of tailings and building waste.
本发明涉及混凝土技术领域，且公开了一种绿色环保混凝土，包括以下重量份数配比的原料一：水泥8％‑20％、再生混凝土骨料25％‑50％、水玻璃0.3％‑1％、氢氧化钠1％‑3.5％、粉煤灰8‑12％、煤矸石6‑15％、剩余部分由水补齐；以下重量份数配比的原料二：水泥8％‑20％、橡胶颗粒25％‑50％、水玻璃0.3％‑1％、氢氧化钠1％‑3.5％、粉煤灰8‑12％、煤矸石6‑15％、剩余部分由水补齐。该绿色环保混凝土，原料中再生混凝土骨料、橡胶颗粒、粉煤灰和煤矸石等成分均由工业废物制成，与传统混凝土原料相比，将混凝土生产时的CO2排放大大降低，再生混凝土骨料进行特殊处理后取代河砂和石子再于水泥混合制成再生混凝土，用到新建筑的重建中，解决尾矿和建筑废料的处理问题。
