矿渣微粉品质差别及其对混凝土性能的影响

Quality Differences of Grounded Slag Powders and the Influences on Concrete Properties

通过试验研究了不同品种矿渣微粉对水泥胶砂和混凝土质量的影响情况,在此基础上对作为掺合料使用的几种矿渣微粉的品质进行了分析及评述,指出矿渣微粉中外加的一些活性组分虽然能提高其检验时的某些指标值,但会对混凝土的质量造成不利影响,因此,从质量控制的角度来说,混凝土用户应该采用不掺其他组分的矿渣微粉。

Based on tests of the effects of several slag powders with different qualities on the properties of cement mortar and con- crete, it has been analyzed and evaluated on the qualities for above-mentioned slag powders. And it＇s pointed out that, when adding some reactive components into the slag powder, there are certain unfavourable effects to concrete qualities, although it can euhance the measred data for checking the products. Therefore, from the view points of qulity control, it must be taken as the concrete＇s admixture for the slag powder without any other component.
