短句来源
In order to explore the effects of particls size distribution on structure and properties of cement paste,based on measuring the water requirements of slag with different size distributions on the same fluidity degree,it was revealed the that different size distributions determine different packing densities,and the formula of packing density with continuous particle size distribution for cement paste was developed.
为了研究粒径分布对水泥石结构与性能的影响,通过测定多组粒径分布不同的矿粉在流动度相同情况下的需水量,得到矿粉不同粒径分布所对应的不同的堆积密度,推导了浆体中连续粒径粉体的堆积密度公式。
