摘要:
采用火山灰活性量化分析方法,运用胶砂强度、活性效应比强度系数、活性指数等指标对比分析了磨细锶渣、磨细矿渣和粉煤灰三者之间的活性效应.分析表明,胶砂强度可以评价胶砂试件的砂浆强度,但不能量化其中掺合料的强度贡献;而比强度指标可对各个龄期水泥胶砂试件中掺合料的活性效应,及其在胶砂试件总强度中所占的强度百分率进行量化评价,弥补了胶砂强度分析的缺陷.所研究的掺合料中,磨细矿渣及煅烧磨细锶渣的活性效应最好,且前者的后期活性较好,而后者更有利于早期的活性发展.
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.
