研究了硅酸盐水泥添加钢渣膨胀剂后的物理化学性能和膨胀性能。调节钢渣的细度和掺量,可改变硬化浆体的膨胀大小。并探讨了钢渣水泥膨胀剂的膨胀机理,提出了膨胀是由于钢渣中游离氧化钙水化产物局部堆积,使空隙体积增加,产生表观体积膨胀的观点。

Chemical and physical properties and expansive property have been studied for steel slag expansive cement. The influence of steel slag proportions and fineness on expansion are presented.This paper discuss the expanding mechanism and typical properties of steel slag expansive cement. The hydration of free-lime in steel slag leads to the hydrates local accumulation,the volume increase of void and the apparent volume expansion.
