Scrap iron-hematite counterweight concrete and preparation method thereof
The invention relates to scrap iron-hematite counterweight concrete. The scrap iron-hematite counterweight concrete comprises a cementing material, coarse aggregate, fine aggregate, water and an additive, wherein the cementing material comprises cement, slag and steel slag powder, the coarse aggregate comprises hematite ore, and the fine aggregate comprises hematite ore sand, scrap iron and boron glass powder. The invention relates to scrap iron-hematite counterweight concrete. The mass ratio of a cementing material to coarse aggregate to fine aggregate to water to an additive is 1: 3.84: 3.11: 0.41: 0.01; in the cementing material, the mass ratio of cement to slag to steel slag powder is 7: 2: 1; in the fine aggregate, the mass ratio of the hematite sand to the scrap iron to the boron glass powder is 1: 1.28: 0.49; the water-binder ratio is 0.41. The invention further relates to a preparation method of the scrap iron-hematite counterweight concrete. The volume weight of the concrete is greatly improved on the premise that the strength of the concrete is guaranteed, and the method belongs to the field of building construction.
本发明涉及一种铁屑‑赤铁矿配重混凝土，包括胶凝材料、粗集料、细集料、水、外加剂；其中，胶凝材料包括水泥、矿渣、钢渣粉，粗集料包括赤铁矿石，细集料包括赤铁矿砂、铁屑、硼玻璃粉。一种铁屑‑赤铁矿配重混凝土，质量比为胶凝材料：粗集料：细集料：水：外加剂＝1：3.84：3.11：0.41：0.01；胶凝材料中，质量比为水泥：矿渣：钢渣粉＝7：2：1；细集料中，质量比为赤铁矿砂：铁屑：硼玻璃粉＝1：1.28：0.49；水胶比为0.41。还涉及一种铁屑‑赤铁矿配重混凝土的制备方法。本发明在保证混凝土强度的前提下大大提高了混凝土的容重，属于建筑施工领域。
