‘Waterproofing and durability of Water treatment structures including sewage’
Concrete deteriorates for many different reasons and could start as early as 5 years, and the most known are as follows: Reinforcement corrosion (Mainly due to chloride ions, and/or carbonation in the presence of water and oxygen), freeze and thaw, the internal Alkali Silica Reactions, the external chemical attacks, and the Microbially Induced Corrosion (MIC) caused by the AcidiThioBacillus TheoOxidans (Cement eaters) and AcidiThioBacillus FerroOxidans (Steel eaters). Penetron explains how they occur and offer solutions on how to prevent them from happening in the first place, hence extending the life of the structure even beyond the design life.
