Highway cement-free all-solid-waste stabilizing material and preparation method thereof
The invention relates to the technical field of concrete, and discloses a cement-free all-solid-waste stabilizing material for a road and a preparation method of the cement-free all-solid-waste stabilizing material. Comprising steel slag aggregate and a steel slag-based cementing material, the particle size of the steel slag aggregate is smaller than or equal to 20 mm, the steel slag-based cementing material comprises steel slag powder, blast furnace slag or slag powder, desulfurized gypsum and water glass, and the steel slag-based cementing material is prepared by adding water and stirring and mixing; the 28d breaking strength of the steel slag-based cementing material reaches 5-9 MPa, and the 28d compressive strength of the steel slag-based cementing material reaches 30-50 MPa; the 7d unconfined compressive strength of the cement-free all-solid waste stable material for the road is 3-7MPa. The mass of the steel slag aggregate accounts for 90-97% of the total mass of the cement-free all-solid waste stable material for the road. According to the invention, a large amount of steel slag aggregate and other solid wastes are consumed, the 7d unconfined compressive strength of the cement-free all-solid-waste stable material for the road is 3-7MPa, and a large amount of solid wastes are effectively used as raw materials to produce the valuable water stable material for the road for national engineering construction.
本发明涉及混凝土技术领域，公开了一种公路无水泥全固废稳定料及其制备方法。包括钢渣集料和钢渣基胶凝材料，所述钢渣集料粒径小于或等于20mm，所述钢渣基胶凝材料包括钢渣粉、高炉渣或矿渣粉、脱硫石膏、水玻璃，加水搅拌混合制成；所述钢渣基胶凝材料28d抗折强度达5～9MPa，28d抗压强度达30～50MPa；所述公路无水泥全固废稳定料7d无侧限抗压强度为3～7MPa。所述钢渣集料质量在所述公路无水泥全固废稳定料总质量占比90％～97％。本发明消耗了大量钢渣集料和其它固废，公路无水泥全固废稳定料7d无侧限抗压强度为3～7MPa，有效将大量固废做为原料生产出用于国家工程建设的有价值公路水稳料。
