Beschreibung
Zusammenfassung:	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 th
