Self-alkali-activated solid waste early strength C30 concrete and preparation method thereof
The invention is suitable for the technical field of concrete, and provides self-alkali-activated solid waste early strength C30 concrete, which is prepared from the following raw materials in parts by weight: 240 to 280 parts of ordinary Portland cement, 80 to 120 parts of fly ash, 40 to 80 parts of composite admixture, 1700 to 1900 parts of recycled aggregate, 160 to 180 parts of water and 0.7 to 1.0 part of water reducing agent. The invention also provides a preparation method of the self-alkali-activated solid waste early strength C30 concrete. According to the invention, the concrete waste material is used as a renewable resource, so that the emission of wastes in the concrete industry is reduced, the carbon emission in the industry is also reduced, the green development of the building material industry is facilitated, and the construction waste transportation cost and the concrete preparation cost of premixed concrete enterprises are reduced; the alkalinity of the concrete waste slurry is compounded with the mineral powder, and the early activity of the mineral powder is improved through high alkalinity and heating of the waste slurry, so that the adverse effect of other alkali excitants on the concrete is reduced, and the production cost is also reduced.
本发明适用于混凝土技术领域，提供了一种自碱激发固废早强C30混凝土，包括以下重量份的原料：普硅水泥240‑280份、粉煤灰80‑120份、复合掺合料40份‑80份、再生骨料1700‑1900份、水160‑180份、减水剂0.7‑1.0份。本发明还提供了一种自碱激发固废早强C30混凝土的制备方法。本发明利用混凝土废弃物料作为再生资源，既降低了混凝土行业废弃物的排放，也降低了行业的碳排放，有利于实现建材行业绿色发展，降低了预拌混凝土企业的运输建筑垃圾费用和混凝土制备成本，利用混凝土废浆本身的碱性与矿粉复配，通过废浆高碱性并加热提高矿粉的早期活性，降低了利用其他碱激发剂对混凝土不良影响的同时，也降低了生产成本。
