Steel slag powder cementing material and preparation method thereof, and steel slag powder high-strength concrete prepared from steel slag powder cementing material
The invention relates to the technical field of building materials, in particular to a steel and iron slag powder cementing material, a preparation method and steel and iron slag powder high-strength concrete.The steel and iron slag powder cementing material is composed of blast furnace slag, dry steel slag, tailing slag, lithium slag and cement. The utilization rate of the steel slag micro-powder, the slag micro-powder, the tailing slag and the lithium slag can be remarkably increased, accumulation of industrial waste is reduced, environmental pollution is reduced, meanwhile, the characteristics of high early strength, good fluidity and good filling performance of the high-specific-surface-area slag powder are utilized, the performance indexes such as strength and durability of common steel slag powder concrete are improved, and the service life of the concrete is prolonged. When the steel slag powder composite cementing material is applied to concrete engineering, concrete can have high working performance and mechanical performance and excellent durability, and remarkable economic benefits and social benefits are achieved.
本发明涉及建筑材料技术领域，具体的涉及一种钢铁渣粉胶凝材料及制备方法、利用其得到的钢铁渣粉高强混凝土，其中钢铁渣粉胶凝材料由高炉矿渣、干钢渣、尾矿渣、锂渣和水泥组成，制备工艺简单，能显著增大钢渣微粉、矿渣微粉、尾矿渣、锂渣的利用率，减少工业废弃物的堆积，减少环境污染，同时利用高比表面积矿渣粉早强高、流动性好、填充性好的特点，提高普通钢铁渣粉混凝土的强度和耐久性等性能指标，将该钢铁渣粉复合胶凝材料用于混凝土工程中，能使混凝土具有较高的工作性能、力学性能，以及较优的耐久性，具有显著的经济效益和社会效益。
