摘要
通过室内试验的方式配置了清水、浓度50000mg/L和100000mg/L的硫酸镁溶液,通过对外、强度、质量变化率和相对动弹模量对混凝土的宏观性能演变规律进行研究.结果表明,在100000mg/L的硫酸镁溶液中相比浸泡前混凝土相对动弹模量降低近80%,由此可知,高浓度的硫酸镁可对混凝土造成严重的腐蚀.
Abstract
By way of indoor test,clear water,and magnesium sulfate solution with a concentration of 50 000 mg/L and 100 000 mg/L were configured,and the macroscopic property evolution law of concrete was studied by appearance,strength,mass change rate,and relative dynamic elastic modulus.The results showed that,in 100 000 mg/L magnesium sulfate solution,the relative dynamic modulus of concrete was reduced by nearly 80%compared with that before immersion.It shows that the high concentration of magnesium sulfate caused serious corrosion to the concrete.
