Unfired refractory admixture, preparation method thereof and concrete
The invention provides an unfired refractory admixture, a preparation method thereof and concrete. The unfired refractory admixture provided by the invention comprises the following raw materials: 20-50 parts of casting ash, 50-80 parts of industrial waste residues, 5-15 parts of desulfurized gypsum, 0-2 parts of an exciting agent, 0-2 parts of an early strength agent and 0-0.2 part of a solid water reducer. The unfired refractory admixture provided by the invention is prepared by matching the casting ash, the industrial waste residues, the desulfurized gypsum, the exciting agent, the early strength agent and the solid water reducing agent according to a certain proportion, and the specific casting ash is adopted as one of the main raw materials and is matched with the other components, so that part of cement can be replaced, and the production cost of concrete is reduced; the strength of the concrete can also be obviously improved. Moreover, a large amount of other industrial waste residues are adopted as main raw materials, so that the problem of environmental pollution caused by solid waste accumulation treatment can be effectively relieved, and the hidden danger of environmental pollution is reduced.
本发明提供了一种免烧耐火掺合料及其制备方法，以及混凝土。本发明提供的免烧耐火掺合料的原料包括：20～50份铸造灰，50～80份工业废渣，5～15份脱硫石膏，0～2份激发剂，0～2份早强剂，0～0.2份固体减水。本发明提供的免烧耐火掺合料，将铸造灰、工业废渣、脱硫石膏、激发剂、早强剂和固体减水剂以一定比例搭配制得，其中采用特定的铸造灰作为主要原料之一，与上述其它组分搭配，不仅可以替代部分水泥，降低混凝土生产成本，还能显著提高混凝土的强度。而且，本发明采用大量其它工业废渣作为主要原料，能够有效地缓解固体废弃物堆积处理带来的环境污染问题，降低环境污染隐患。
