We provide anti carbonation coating for RCC  and concrete structure. Anti carbonation is done on when the structure is exposed extreme weather conditions. The corrosion of reinforcement which takes place is a complex electrochemical processes due to the ingress of either moisture, chloride,iron or ingress of combined deleterious substances through the porous concrete and accelerated with other catalyst factors such as mean temperature, relative humidity and wind pressure. Thereby deterioration of RCC structures become very fast which need protection by suitable anti carbonation coating to increase there service life.
