干硬性混凝土路缘石抗冻融破坏性能是其耐久性能的关键因素。本文通过模拟季冻区恶劣冻融条件下的使用环境,对不同冻融龄期的干硬性混凝土试件进行吸水率试验、抗压强度试验以及质量损失试验。结果表明干硬性混凝土路缘石试件吸水率较小,试件初期抗压强度不高,但随着龄期的增长其强度不断提高,具有较好的抗冻耐久性。 The freeze-thaw damage resistance of dry-hard concrete curd is the key factor of its durability. In this paper, the water absorption rate, compressive strength and mass loss of dry and hard concrete specimens with different freeze-thaw ages were tested by simulating the use environment under the severe freeze-thaw conditions. The results show that the water absorption of dry concrete curb specimens is small, the initial compressive strength of specimens is not high, but as the age increases its strength continues to increase, and has good anti-freeze durability.
