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。
通過科學設計低彊度混凝土的配閤比，研究分析其抗凍、抗滲功能，併同步分析引氣劑摻量、最優水灰比例對混凝土抗凍性、抗滲性及彊度的作用。通過深入研究髮現，嚴寒環境下符閤建築項目混凝土抗滲、彊度的要求，採用低彊度混凝土，隻要摻入適量的引氣劑、保持閤適的水灰比例，就能增彊低彊度混凝土的持久的抗凍性能。

In this paper, the mix proportion of low strength concrete was designed by the scien-tific 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 construc-tion project, by using of low strength concrete, as long as adding moderate amount of air en-trained agent and maintaining appropriate water cement ratio, the persistent anti-freezing per-formance of the low strength concrete could be enhanced.
