摘要: 为了研究二灰钢渣混合料的路用性能,进行了3 种配比的二灰钢渣混合料抗冻性能、干缩性能、抗冲刷性能试 验,并与二灰碎石类集料对比分析。结果表明: 二灰钢渣的抗冻性能优于二灰碎石,而其干缩系数明显小于同配比 二灰碎石; 配比为5∶15∶80 的二灰钢渣抗冻性能、抗干缩性能、抗冲刷性能均最优。

关键词: 二灰钢渣, 抗冻, 干缩, 抗冲刷

Abstract: In order to study the pavement performance of lime-fly ash slag,the frost resistance,dry-shrinkage property, scour resistance experiments of 3 kinds of lime-fly ash slag mixtures are performed. The experiment shows that the antifreezing and thawing performance of lime-fly ash slag mixture is better than that of lime-fly ash broken stone; the shrinkage coefficient is much less than that of lime-fly ash broken stone with the same mix proportion. And the frost resistance,dryshrinkage property,scour resistance of lime-fly ash slag is best when the mixture proportion ratio is 5∶15∶80.

Key words: lime-fly ash slag, frost resistance, dry-shrinkage, scour resistance
