All-solid-waste zero-carbon concrete and preparation method thereof
The invention belongs to the technical field of concrete materials, and relates to full-solid waste zero-carbon concrete which is prepared by mixing a cementing material, aggregate and water according to the mass ratio of (15-25): (60-80): (10-15) at normal temperature and normal pressure, the cementing material is prepared by mixing a high-alkalinity solid waste material, a high-sulphoaluminate solid waste material, a high-aluminosilicate solid waste material, an organic solid waste material and a composite admixture according to the mass ratio of (1-3): (1-3): (1-3): (1-3): (1-3); the aggregate is prepared by crushing, screening and grading a tailing solid waste material. Based on the joint excitation principle of industrial, agricultural and urban solid wastes, wastes are treated by wastes, and the concrete meeting the C40 strength can be prepared by synergistically utilizing multiple solid wastes under the conditions of normal temperature and normal pressure. The carbon emission in the cement concrete industry is favorably reduced, and the environmental pollution caused by industrial solid waste, agricultural solid waste and urban solid waste is reduced.
本发明属于混凝土材料技术领域，涉及一种全固废零碳混凝土，所述混凝土包括胶凝材料、骨料和水按照15~25：60~80:10~15的质量比在常温常压下混合制备；所述胶凝材料为高碱性固废材料、高硫铝酸盐固废材料、高硅铝酸盐固废材料、有机固废材料和复合掺合料按照1~3：1~3：1~3：1~3：1~3的质量比混合制得；所述骨料为尾矿固废材料经破碎和筛分级配后制备而成。本发明基于工农城固废联合激发原理，以废治废，在常温常压条件下，可实现多元固废协同利用制备出满足C40强度的混凝土。有利于降低水泥混凝土行业碳排放，减少工业固废、农业固废和城市固废的污染环境。
