摘要
研究了引气剂掺量、粉煤灰掺量、水胶比和强度对混凝土抗冻性能的影响。结果表明,粉煤灰混凝土的引气量、水胶比、强度是影响其抗冻性的决定因素,推荐了粉煤灰混凝土在严寒地区提高抗冻性的最佳引气量和最佳水胶比控制范围。
Studies on the effects of frost resistance of concrete in different air entraining agents, fly ash contents,water binder ratios and strength. The results indicated that air entraining agents,water binder ratios, strength had significant effects on the frost resistance of concrete with fly ash.The optimum value of air entraining agents,water binder ratios for frost resistance of fly ash concrete in the frosty area are recommended.
