辽北近代历史建筑中混凝土材料的劣化机理研究
发布时间：2018-08-17 13:38
【摘要】：辽北近代历史建筑因其物质真实性、文化特殊性、地域特定性均具有较高的研究价值和保护价值,然而目前仍缺失科学与完善的保护,亟待建立健全的修缮技术链条。对以混凝土为代表材料的劣化形态进行梳理,统计其开裂、脱落、泛碱与污斑现象的分布,进而分析其劣化机理,提出水分渗入、冻融循环和微生物侵蚀为其劣化的主要因素,是建立该技术链条的初始环节,也是后续研究的必然基础。
[Abstract]:Because of its material authenticity, cultural particularity and geographical specificity, the modern historical buildings in northern Liaoning have high research value and protection value. However, there is still a lack of scientific and perfect protection, and it is urgent to establish a sound repair technical chain. The deterioration morphology of concrete as the representative material is combed, the distribution of cracking, shedding, pan-alkali and stain phenomenon is counted, and the mechanism of deterioration is analyzed. The main factors of deterioration are water infiltration, freeze-thaw cycle and microbial erosion. It is the initial link of establishing the technical chain and the inevitable foundation of subsequent research.
