Preparation method of lime-free molybdenum tailing autoclaved aerated concrete
The invention discloses a preparation method of lime-free molybdenum tailing autoclaved aerated concrete. The autoclaved aerated concrete is prepared from the following raw materials: 100 to 150 parts of molybdenum tailings, 40 to 60 parts of water-quenched slag, 30 to 50 parts of cement, 5 to 10 parts of waste slurry, 8 to 15 parts of gypsum, 2 to 6 parts of aluminum powder paste, 0.1 to 0.5 part of a water reducing agent, 0.5 to 1 part of a modifier, 0.5 to 1 part of an additive and 200 to 250 parts of water. The molybdenum tailings and the water-quenched slag are used for replacing traditional siliceous materials such as river sand and fly ash to prepare the autoclaved aerated concrete, so that the environmental problem caused by stockpiling of the molybdenum tailings can be solved, waste is turned into wealth, meanwhile, the water-quenched slag is reasonably utilized, the production cost is reduced, and a good effect is achieved on sustainable development of the society. The prepared autoclaved aerated concrete has good water resistance, oil resistance and compression resistance, meanwhile, the seawater corrosion resistance is good, and the autoclaved aerated concrete can be used in the marine environment.
本发明公开了一种无石灰钼尾矿蒸压加气混凝土的制备方法，该蒸压加气混凝土原料包括钼尾砂100～150份、水淬渣40～60份、水泥30～50份、废料浆5～10份、石膏8～15份、铝粉膏2～6份、减水剂0.1～0.5份、改性剂0.5～1份、外加剂0.5～1份和水200～250份。本发明以钼尾矿和水淬渣代替河砂、粉煤灰等传统硅质材料，用于制备蒸压加气混凝土，这样可以解决钼尾矿堆存所引起的环境问题，实现变废为宝，同时合理利用水淬渣，降低生产成本，对社会的可持续发展起到良好的效应。制备所得的蒸压加气混凝土具有良好的耐水性和耐油性及抗压性能，同时其抗海水腐蚀性好，可用于海洋环境中。
