摘要
矿渣粉作为综合性能最为优良的人造矿物原料,为确定其作为活性掺合料在耐久性混凝土中的作用,通过选择不同掺量进行试验,测定混凝土的和易性、泌水、坍落度损失及7 d和28 d强度,并对实验效果比较好的掺量进行抗冻融试验和抗渗试验,证明合理应用矿渣粉不仅可以改善混凝土的和易性、提高混凝土的抗渗性及抗冻性,同时可以提高混凝土的抗裂和耐腐蚀性能。
Slag powder as the most comprehensive performance of synthetic materials,good for the mineral admixture activity as the role in the durability of concrete with different content determination of experiments, the concrete workability, lactation, slump and water loss and 7 and 28 days, and the experimental results strength are relatively good dosage freezing-thawing resisting testing and permeability test proved rational application of slag powder, not only can improve the concrete workability, improve the anti-permeability and concrete, while improving frost resistance of concrete crack and corrosion resistance.
