在水灰比为0.70的1：2.75混合料上，研究了三种填料(石灰石、白云岩和玄武岩)对水泥砂浆强度的影响。填料含量为水泥重量的10%至40%，其细度(比表面积)为1150至11200平方英尺。结果证实了早先的结论，即填料对强度的影响主要是对水泥水化的加速作用。随着填料含量和细度的增加，所有非火山灰填料的强度提高基本上是相同的。强度的提高部分归因于与使用填充剂相关的混合物密度的增加(即较低的空气含量)。有一些间接证据表明，当最细的石灰石填料(10,300平方英尺)形成碳铝酸钙。厘米/克)。然而，这种阵型显然不会影响力量。
The effect of three fillers (ground limestone, dolomite and basalt) on the strength of cement mortars was studied on 1:2.75 mixes having a w/c ratio of 0.70. The filler content ranged from 10 to 40% of the cement weight and their fineness (specific surface) from 1,150 to 11,200 sq. cm per g. Results confirmed earlier conclusions that fillers effect on strength is primarily an accelerating effect on the cement hydration. The improvement in strength is essentially the same for all non-pozzolonic fillers increasing with both filler content and fineness. In part, this improvement in strength is attributable to the increase in the density of the mix (i.e. a lower air content) associated with the use of fillers. There is some indirect evidence that monocalcium carboaluminate is formed when the finest limestone filler (10,300 sq. cm per g) is used. This formation, however, apparently does not affect strength.
