Study on corrosion effects under sulfate attack of concrete at a dry-wet circulation environment;
干湿交替环境下混凝土硫酸盐侵蚀的试验研究
Sulfate attack is a very important effect to the concrete durability,however,the environment of concrete is not only sulfate attack,in fact,the concrete sometimes gets two factors of external environment and sulfate attack,such as dry-wet circulation etc.
硫酸盐侵蚀对混凝土的耐久性有重要影响,但在实际工程中混凝土往往不是处于硫酸盐单一的作用环境中,混凝土往往受到外界环境条件和硫酸盐侵蚀双重因素的作用,如干湿交替等。
Based on the situation of the concrete sulfate attack always exists in complex factors,the present research of the concrete sulfate attack is elaborated at a dry-wet circulation and carbonation environment,and experiments are used to prove that the dry-wet circulation and carbonation can accelerate the sulfate attack,some ideas for the future research are provided.
依据现实情况中混凝土硫酸盐侵蚀往往是在多因素的作用下,阐述了国内外对于环境因素中的干湿交替和碳化对混凝土硫酸盐侵蚀的研究现状,并通过试验证明了干湿循环和碳化对混凝土硫酸盐侵蚀的加速作用,为以后的研究提供一些参考。
