分析影响公路附属设施混凝土构件表观抗冻耐久性的因素,并提出解决方案,以提高混凝土构件的表观抗冻耐久性,延长其使用寿命。采用室内试验的研究方法,获得不同配合比组成、不同环境条件下的冻融质量损失百分率试验数据。通过对试验数据的整理分析,给出提高混凝土构件表观抗冻耐久性的合理配合比组成。
The factors which affect the apparent antifreeze durability of the concrete members of the highway auxiliary facilities are analyzed and the solutions are proposed to improve the apparent antifreeze durability of the concrete members and prolong the service life of the concrete members. The experimental data of the percentages of freeze-thaw mass loss under different environmental conditions were obtained by laboratory test. By analyzing and analyzing the experimental data, the reasonable composition ratio of improving the apparent anti-freeze durability of concrete components is given.
