摘　　要：通过科学设计低强度混凝土的配合比,研究分析其抗冻、抗渗功能,并同步分析引气剂掺量、最优水灰比例对混凝土抗冻性、抗渗性及强度的作用.通过深入研究发现,严寒环境下符合建筑项目混凝土抗渗、强度的要求,采用低强度混凝土,只要掺入适量的引气剂、保持合适的水灰比例,就能增强低强度混凝土的持久的抗冻性能.In this paper,the mix proportion of low strength concrete was designed by the scientific method,and its performance of anti-freezing and anti-permeability were studied,and the effect of the air entrainment agent dosage and the optimal water cement ratio on the anti-freezing performance,the anti-permeability performance and the strength of concrete were synchronously analyzed. Through deep research we can find out that in cold environment,the requirements of the anti-permeability performance and the strength of concrete should be meet in the construction project,by using of low strength concrete,as long as adding moderate amount of air entrained agent and maintaining appropriate water cement ratio,the persistent anti-freezing performance of the low strength concrete could be enhanced.
