湿热环境下混凝土受酸雨腐蚀的试验研究
Experimental Study on Acid Corrosion of Concrete in Moist Heat Environment
摘要
Abstract
In order to analyze the corrosion of concrete exposed to the acid rain environment, 3 kinds of solutions with pH of 1.5, 2.5 and 3.5 were prepared to simulate the acid situation. The tests were carried out in an automatic rainfall device with the wet-heat drying cycle method. One hundred C40 concrete specimens were exposed to the different simulated acid environments for certain periods to investigate the variation of concrete appearance, quali⁃ty, neutralization and compressive strength. The results show as follows:Appearance of the concrete deteriorated gradually with the extension of corrosion time;Neutralization depth continued to increase along with time, and the lower the pH of the solution was, the greater the depth of neutralization became;Quality, compressive strength of the concrete decreased briefly first, then increased gradually under the condition of pH of 2.5 and 3.5, but con⁃stantly decreased under the condition of pH1.5.关键词
