摘要
鉴于目前我国尚无植生型生态多孔混凝土的标准冻融试验方法及其抗冻性能的评价指标体系,比较了目前混凝土常见的冻融试验方法,并通过试验探究了生态多孔混凝土冻融试验方法及其抗冻性能的评价指标。试验表明:润湿状态下的快速冻融试验方法可适用于生态多孔混凝土;相对动弹模量、质量损失率及试件外观可以作为生态多孔混凝土抗冻性能的评价指标。
In view of the method and evaluation index system of frost resistance of vegetation type eco-porousconcrete without standard test in our country,the domestic common test methods of frost resistance is analyzed andthe freeze-thaw test method and evaluation index of eco-porous concrete are explored.The result shows that thefreeze-thaw cycles method under wetting state can be applied to eco-porous concrete,and the relative dynamicmodulus,mass loss rate and the appearance of the specimen can be used as the evaluation index of the frostresistance of the eco-porous concrete.
