基于掺量的锶渣活性比强度指标分析

分别从胶砂强度值、胶砂抗压强度比和比强度指标三方面分析磨细锶渣作为水泥掺合料的活性效应.结果表明:采用胶砂试件强度值可以得出胶砂强度随磨细锶渣掺量增加而降低的结论,但不能判断磨细锶渣到底有无活性;根据胶砂强度比可以判断磨细锶渣是水泥的活性掺合料,并且抗折活性大于抗压活性,但该方法不能定量地描述各个龄期下,不同掺量磨细锶渣对水泥胶砂强度所起的作用;采用比强度指标可以明确表明不同掺量的磨细锶渣对水泥胶砂所起的作用是正面的或负面的,并可量化磨细锶渣活性作用的大小.

Specific strength indicators analysis of the activity of strontium slag based on the amount

Effects of the activity of ground-strontium slag as cement admixture were analyzed from three aspects:mortar strength value,compressive strength ratio of mortar and specific strength indicators.The results show that:the conclusion that the mortar strength reduces with the increase of the amount of ground-strontium slag can be drawn from mortar strength value.But the situation whether ground-strontium slag is active or inactive can't be judged from the mortar strength value.According to compressive strength ...
