Building waste material-based concrete for infilled wall constructional column and preparation method of building waste material-based concrete
The invention relates to the field of C04B28/04, in particular to building waste-based concrete for an infilled wall constructional column and a preparation method of the building waste-based concrete for the infilled wall constructional column, 280-350 parts of waste concrete blocks, 250-320 parts of waste stone, 200-300 parts of cement, 120-180 parts of mineral admixtures, 300-400 parts of river sand, 4-6 parts of admixtures and 170-180 parts of water are adopted for preparing the concrete which is high in strength and good in workability, the production cost is low, and the construction waste-based concrete is suitable for being used for construction. The long-term strength of the concrete is high, the working performance of freshly mixed concrete is good, the problem that the concrete is difficult to construct due to too fast slump loss is avoided, waste concrete blocks and waste stone are treated and screened through a four-stage screening technology and then fully utilized, resource reutilization is achieved, and the method is especially suitable for large-scale industrial application of infilled wall constructional columns and has wide application prospects. The method has important significance for realizing resource utilization of the construction waste and improving the economic benefit.
本发明涉及C04B28/04领域，具体为一种填充墙构造柱用建筑废弃料基混凝土及其制备方法，采用废弃混凝土块280‑350份、废弃石料250‑320份、水泥200‑300份、矿物掺合料120‑180份、河砂300‑400份、外加剂4‑6份、水170‑180份制备得到一种强度高，和易性良好的混凝土，生产成本低，混凝土的后期强度高，新拌和混凝土的工作性能好，避免混凝土由于坍损过快导致施工困难的问题，通过四级筛分工艺，将废弃混凝土块和废弃石料处理筛分后进行充分利用，实现资源化再利用，尤其适用于填充墙构造柱大规模工业化应用，这对于实现建筑垃圾资源化利用并提高经济效益具有重要的意义。
