Abstract:
12 kinds of limeflyashgravel mixture with 3 gradations and 4 margins were designed. The changing features of skeleton state of these mixtures under different interference strengths were studied. The arranging state of coarse aggregate was built according to the averagegrainspaceindex. The test datum were analyzed by photo technology. The results show that: the skeletonareaindex has a good linear relationship with limeflyashmortarmargin, and this relationship can be used to evaluate the skeleton state; the relation curve of skeletonareamodifiedindex with limeflyashmortar margin can be figured, and it can be found that skeletonareamodifiedindex change induced by interference is within the smallest bound when limeflyashmortarmargin is from 50% to 100%. 3 tabs, 4 figs, 12 refs.
