Corrosion Protection for Concrete
ConShield is a concrete admixture for the prevention of hydrogen sulfide generated corrosion common to concrete pipe, manholes and similar structures in municipal sewer environments. As an additive, it permeates the concrete or repair mortar during the mixing phase and molecularly bonds to the cement particles to become an integral component of the hardened product and to create an environment incompatible to harmful bacterial growth.
ConShield becomes an integrated component of the hardened binder. It cannot wash off, delaminate or lose its effectiveness from wear. Scraping or erosion of the concrete surface only serves to expose additional material to the environment that would otherwise foster bacterial growth. As bacterial growth is neutralized, hydrogen sulfide gases released from the raw sewerage cannot be metabolized and converted into sulfuric acid in concentrations sufficient to damage the impregnated concrete and mortar.
ConShield is ideally suited for concrete used to manufacture precast pipe and manholes for use in municipal sewer environments or wherever Thiobacillus bacteria may cause microbiologically induced corrosion (MIC). Repair mortars with ConShield subjected to concentrations of Thiobacillus bacteria in the laboratory have shown complete neutralization.
ConShield is essentially non-toxic and contains no phenols, heavy metals or formaldehyde. It is stable in ultraviolet light and it is leach-resistant.
