水泥组成对胶砂流动度经时损失的影响

The effect of cement compositions on mortar fluidity loss

考察了水泥组成对水泥胶砂流动度经时损失的影响。实验结果表明,水化初期水泥浆体中迅速析出钙矾石,是胶砂流动度损失的主要原因。在不改变熟料的条件下,通过调整水泥组成,可以有效地改善水泥胶砂流动度经时损失。

The effect of cement compositions on mortar fluidity loss is studied.The results of experiments indicate that in the initial stage of hydration ettringite crystal particles are formed rapidly in the cement paste,which is the dominating reason for the mortar fluidity loss.The mortar fluidity loss can be improved by adjusting the compositions of the cement without changing the clinker. 
