High-performance steel-slag-compounded admixture for road base and preparation method thereof
The invention discloses a high-performance steel-slag-compounded admixture for a road base. The high-performance steel-slag-compounded admixture comprises the following components in percentage by mass: 65-75 wt% of steel slag powder and 25-35 wt% of superfine slag powder. The mixing amount of the high-performance steel-slag-compounded admixture in cement is 10-50 wt% in percentage by mass. According to the invention, a series of environmental problems caused by long-term stacking of steel slag can be solved, the early compressive strength of cement is remarkably improved, compressive strengthis hardly reduced after complete curing, and expansion stress is small.
本发明公开了一种用于道路基层的高性能钢渣复合掺合料，成份按质量百分比为：钢渣粉65‑75wt%、超细矿渣粉25‑35wt%。该高性能钢渣复合掺合料在水泥中的掺量以质量分数计为10‑50wt%。该项技术不仅可以解决钢渣长期堆放所引起的一系列环境问题，而且水泥早期抗压强度显著增大，完全固化后抗压强度几乎没有降低，且膨胀应力小。
