摘要: 某工程位于湛江滨海地区,地下水具有中强腐蚀性,但水中含有多种化学组分对硫酸盐结晶腐蚀的速度及强度有阻滞效应,对工程防腐是有益的;针对地下水的具体指标,分析其腐蚀机理,并综合评价得出此工程地下水对混凝土只具有弱腐蚀性。

Abstract: This paper presents a case history of the corrosion study of the groundwater on an underground concrete structure in the coastal area of Zhanjiang. Usually, the groundwater in the coastal area is medium to strong corrosion to the concrete; however, the some chemicals in the groundwater serve retarders for the rate of the sulfate crystallization process. This retard process creates a favorable condition for the corrosion.The comprehensive analysis on the groundwater indicates that the groundwater has only weak corrosion to the concrete structures.
