通过在水泥混凝土加入引气剂,引入大量均匀、稳定、封闭的微小气泡,来提高水泥混凝土路面抵抗除冰盐剥蚀破坏的能力。以混凝土剥落量为评价指标分析了不同含气量对水泥混凝土路面抗盐冻性能的影响。试验结果证实,当水泥混凝土含气量为6%左右时,水泥混凝土路面具有良好的抗盐冻剥蚀性能。 By adding air-entraining agent to cement concrete and introducing a large amount of uniform, stable and closed tiny air bubbles, the ability of the cement concrete pavement to resist deicing and salt denudation and destruction is enhanced. The effect of different gas content on the frost resistance of cement concrete pavement was analyzed based on the amount of concrete spalling. The test results confirm that, when the content of cement concrete is about 6%, the cement concrete pavement has good anti-freezing performance.
