摘要:
应用逾渗理论,损伤力学等相关理论分析水泥混凝土抗冻性中的强度下降问题,对这些逾渗现象进行了分析,提出了唯象学的新观点,合理地解释了当前关于高强混凝土抗冻性研究结果不一致的问题,并进而提出了改进措施.

In this paper, theories, such as percolation theory, damage theory, etc, are adopted to analyze the strength reduction during the freezing and thawing process in cement_based composite. The percolation phenomenom is analyzed and the new theory based on the phenomenology is proposed which can reasonably interpret the non_homogeneity in the research results of the frost resistance of high strength concrete. Further on, improving measures for forst resistance are put forward.
