文章主要研究了含气量、水胶比、辅助性胶凝材料、骨料、纤维等主要材料与配合比参数对混凝土抗盐冻性的影响。对我国东北、华北、西北地区的混凝土路面与桥涵等表面结构物在冬季洒融雪剂条件下,防止盐冻破坏有重要技术参考价值。
The paper mainly studies the influence of gas content, water-cement ratio, auxiliary cementitious materials, aggregates, fibers and other materials on the frost resistance of concrete. It is of important technical reference value for the surface structure such as concrete pavement and bridges and culverts in Northeast China, North China and Northwest China to prevent salt frost damage under the condition of sprinkler agent in winter.
