Mass concrete projects, that are in the process of seepage and corrosion, easily suffer from shrinkage cracks and corrosive-expanding fissures, along with the porous medium characteristic of concrete which are easy for water to permeate. Studying corrosion failure for this kind of material is very important in engineering application. For traditional anti-corrosion designs, comprehensive measures include adding waterproofing agent, smearing waterproof coating and sticking waterproofing membrane. But, for concrete engineering of sewage treatment pools, corrosion failures cannot be prevented effectively. According to the mentioned reasons above, waterproofing and corrosion protection for concrete project of Jiguanshi sewage treatment plant in Chongqing was introduced as an example in this paper. Selection for materials and their engineering effects were also analyzed, and specific technical requirements to improve anti-corrosion durability of concrete were proposed.
