摘要
采用磷酸和柠檬酸缓冲液对两种混凝土进行腐蚀浸泡试验,研究混凝土在两种酸的腐蚀作用下,外观、强度、重量和水泥石矿物组成及微观结构的变化。试验表明,相同pH值下,柠檬酸比磷酸对混凝土具有更强烈的腐蚀作用,它们存在不同的反应机理。
It is carried out that the experimental tests of corrosion to two kinds of concrete, which speciments are respectively immersed in two buffer solutions, citric acid and phosphoric acid. And the changes at aspects of appearance, strength, weight and mineral composition and microstructure of speciments are investigated. The rezults show that, at the same pH valume, the citric acid has the more intensive corrosion to concrete than the phosphoric acid, and the reaction mechanism of two kinds of acid is defferent.
