摘要
在北方寒冷地区,混凝土的抗冻性能直接影响着工程质量和耐久性。从提高混凝土的密实度和采用引气剂这两个途径,对抗冻混凝土的配合比进行了设计。通过对比试验,分析了影响混凝土抗冻性能的因素,确定了符合要求的施工配合比。
In the north cold areas, the cold resistance durability of concrete directly affects the quality and durability of a project. Here, thorough the two approaches of increasing the density of concrete and adopting the air- entraining agent, the mix design of the frost -resistant concrete is made. By comparison test, the factors affecting the cold resistance are analyzed and the mix proportions conforming to the related requirements are determined.
