RCC structure Corrosion

In fact, when we design any RCC structure Corrosion on Reinforcement bar is a major concern and generally when we reach at less than half of designed service life, process of corrosion on reinforcement bar start taking place which proves havoc on the later stages.

Presently different Anti corrosive coatings like Cement Polymer Composite Coating (CPCC), Epoxy Coating, Fusion Bonded Epoxy Coating, Cement Slurry Coating- 4 step treatment etc. are available in the market.

As the process of coating on reinforcement bar has different demerits &limitations there was a great demand to develop some effective, economical, low dosage & user friendly additive which can be mixed while making concrete at site or at RMC Plant itself without adversely affecting physical properties of concrete to enhance corrosion free service life of RCC structures.
