由于混凝土随着气候变化、化学侵蚀、磨损或其他的原因而受到不同程度的破坏,而承受各种破坏的能力就是混凝土的耐久性。耐久的混凝土在暴露的条件下一般会保持其形态、质量及使用功能。本文选取合适配比,进行实验得出结论与机理分析验证,力求提高混凝土性能,作用国民经济建设。1.混凝土冻融理论研究对于混凝土冻融破坏的研究一直是国内外建筑行业的热点议题。它的理论研究有很长的历史,如今的研究也很深入。其大部分的
Due to concrete with climatic changes, chemical erosion, wear and tear or other causes and to varying degrees of damage, and to withstand a variety of damage ability is the durability of concrete. Durable concrete will generally retain its form, quality, and serviceability under exposed conditions. In this paper, the selection of the appropriate ratio, the experimental conclusion and analysis of the mechanism to verify and strive to improve the performance of concrete, the role of national economic construction. 1. Research on the Theory of Freeze-Thawing of Concrete The research on the freeze-thaw damage of concrete has always been a hot issue in the construction industry at home and abroad. Its theoretical research has a long history, and the research of today is also very deep. Most of it
