与掺粉煤灰混凝土相比,掺黄磷渣或矿渣微粉混凝土的后期力学性能均有所提高,除早期干缩略大外,其耐久性、热学性能均比粉煤灰碾压混凝土略优;将黄磷渣或矿渣微粉作为碾压混凝土掺和料使用,既可以减少环境污染,同时还可以缓解水工大体积碾压混凝土掺和料的供求矛盾。本文拟对黄磷渣微粉与矿渣微粉在混凝土中使用效果进行对比分析。
Compared with fly ash concrete, yellow phosphorus slag or slag mixed with concrete posterior mechanical properties are improved, except early dry shrink slightly larger, the durability and thermal properties are slightly better than the fly ash roller compacted concrete ; The yellow phosphorus residue or slag powder as a roller compacted concrete admixture use, both to reduce environmental pollution, but also can ease the contradiction between supply and demand of hydraulic large volume roller compacted concrete admixture. This article intends to yellow phosphorus slag and slag powder in the concrete use of comparative analysis.
