摘要
阐述了钢渣形成过程及基本物理化学性质、钢渣国内外利用现状、轨枕及轨枕混凝土的研究现状。钢渣应用到轨枕混凝土当中,由于表面坚固多孔,水泥渗入到颗粒孔洞中,伴随着水泥凝结硬化颗粒间结合时能够紧密相连,使得混凝土轨枕具有更高的强度及更大的道床阻力,提高了轨枕的耐久性,为钢渣的处理又多了一条新途径。
It expounds the forming process and basic physical and chemical properties of steel slag,steel slag utilization at home and abroad,the status of study on concrete sleeper and sleeper.Steel slag concrete applied to the sleeper,due to cement particles into the surface hole,with the combination between cement particles condense sclerosis can closely linked,it makes concrete sleeper has higher strength and more ballast resistance,and improves the durability of the sleeper,which provides a new way to process steel slag.
