Light high-strength foam concrete doped with tailing sand and preparation method thereof

The invention discloses tailing sand-doped lightweight high-strength foam concrete and a preparation method thereof. The tailing sand-doped lightweight high-strength foam concrete is prepared from the following raw material components in parts by mass: 650 to 850 parts of cement, 50 to 150 parts of fly ash, 100 to 300 parts of tailing sand, 350 to 500 parts of water, 0.9 to 1.2 parts of physical foaming agent, 3 to 5 parts of water reducing agent, 2 to 5 parts of fiber and 4 to 10 parts of graphene oxide. The tailing sand foam concrete is prepared by adopting a physical foaming method, so that the problem that the existing tailing sand foam concrete is difficult to achieve light weight and high strength is solved, the consumption of cement is reduced, the energy is saved, the environment is protected, and the comprehensive performance is relatively outstanding. 本发明公开了一种掺尾矿砂的轻质高强泡沫混凝土及其制备方法，其中掺尾矿砂的轻质高强泡沫混凝土的原料组分按质量份数包括：水泥650～850份，粉煤灰50～150份，尾矿砂100～300份，水350～500份，物理发泡剂0.9～1.2份，减水剂3～5份，纤维2～5份，氧化石墨烯4～10份。本发明采用物理发
