Concrete composite admixture prepared by comprehensively utilizing industrial waste residues and construction waste
The invention relates to a concrete composite admixture prepared by comprehensively utilizing industrial waste residues and construction waste. The concrete composite admixture comprises the following components: metal smelting waste residues, construction waste, industrial waste residues, stone processing process waste and fine waste of machine-made sand produced by stone chips. The concrete composite admixture has the advantages that bulk industrial solid waste and construction waste are taken as main bodies, the composition of materials is adjusted according to local conditions, and multifunctional materials of local industrial waste residues, processing waste and construction waste are compounded and combined flexibly, and more excellent performance is obtained; and the concrete composite admixture is suitable for popularization and application, the utilization amount and the utilization rate of the bulk solid wastes are increased, further development of a composite admixture technology can be promoted, the production cost of the composite admixture is reduced, local industrial solid waste residues can be really blocked from the source, zero emission of the industrial solid waste is achieved, mineral powder, fly ash, cement and the like can be replaced on the premise that the working performance of concrete is guaranteed, the production cost of the concrete is reduced, and huge social benefits and economic benefits are obtained.
本发明涉及一种工业废渣和建筑垃圾综合利用的混凝土复合掺合料，其包括以下成分：金属冶炼废渣、建筑垃圾、工业废渣、石材加工过程废料、石屑生产机制砂的细废料。本发明优点在于：以上述大宗工业固体废弃物和建筑垃圾为主体，因地制宜，根据本地工业废渣、加工废料和建筑垃圾多功能材料复合，组合灵活，性能更优，适合推广应用，不仅提高了大宗固废利用量和利用率，更能推动复合掺合料技术进一步发展，降低复合掺合料的生产成本，并能力求真正实现当地工业固体废渣从源头堵截，做到工业固废零排放，在保证混凝土工作性能的前提下，可替代矿粉、粉煤灰及水泥等，降低混凝土的生产成本，具有巨大的社会效益和经济效益。
