【摘要】：遼北近代歷史建筑因其物質(zhì)真實性、文化特殊性、地域特定性均具有較高的研究價值和保護價值,然而目前仍缺失科學(xué)與完善的保護,亟待建立健全的修繕技術(shù)鏈條。對以混凝土為代表材料的劣化形態(tài)進行梳理,統(tǒng)計其開裂、脫落、泛堿與污斑現(xiàn)象的分布,進而分析其劣化機理,提出水分滲入、凍融循環(huán)和微生物侵蝕為其劣化的主要因素,是建立該技術(shù)鏈條的初始環(huán)節(jié),也是后續(xù)研究的必然基礎(chǔ)。
[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.
