- Abstract:
- The quantitative analysis method of volcanic ash activity was used to compare and analyze the activity effects between fine strontium slag, fine grinding slag and fly ash by comparing and analyzing the strength of rubber sand, the specific strength coefficient of active effect and the activity index. The analysis shows that the strength of the rubber sand can evaluate the mortar strength of the rubber sand specimen, but cannot quantify the strength contribution of the admixture. The specific strength index can quantitatively evaluate the active effect of admixtures in cement sand specimens of various ages and the strength percentage in the total strength of cement sand specimens, which makes up for the shortcomings of sand strength analysis. Among the admixtures studied, the active effect of grinding fine slag and calcined fine strontium slag was the best, and the former had better later activity, while the latter was more conducive to early activity development.
