| 摘 要： | 在单掺矿渣的水泥中,熟料和矿渣比表面积的增大,均降低了水泥净浆的流变性;在试验条件下得出,浆体流动度L与比表面积S呈线性关系:L矿渣,30min=110-0.041(S-326),L熟料,30min=121-0.147(S-265);从直线斜率上看出,熟料对水泥净浆流动度的影响远大于矿渣的影响程度。 |

| Abstract: | If the cement admixed with slag only, the rheology of cement paste decreased with the increase of the specific surface area of clinker and slag. The linear relation between the fluidity of cement paste （L） and specific surface area （S） of clinker or slag shown as the following equation： Lslag,30min=110-0.041 （S-326）,Lclinker,30min=121-0.147 （S-265）. The difference of the influence of the fineness of clinker and slag on cement paste fluidity, the clinker was much evidently than the slag, could been clearly observed with the slop of the curves. |
