The result shows that blended cement mixed with activatory coal gangue powder has high compressive strength , however , with the increase of the admixture of coal gangue powder , flowability of blended cement paste become worse , and the setting time is not obviously affected 结果表明,掺入经活化处理的煤矸石粉配制的混合水泥具有较好的强度性能;随掺量增加,水泥浆体的流变性能变差,但对凝结时间并无明显影响。
The activatory coal gangue powder ( acgp ) , ground cement clinker and natural gypsum are mixed by different ratios to prepare blended cement specimens , and its mortar compressive strength performance , water usage for standard consistency , and flowability of mortar are investigated 摘要将经燃烧等过程进行活化处理的煤矸石细粉与磨至一定比表面积的水泥熟料及天然生石膏混合均匀,制成了活化谋矸石粉掺量比例不同的多组混合水泥,并对其胶砂强度性能、标准稠度用水量、胶砂流动度进行了实验检测。
