Reinforcing Mesh

Corrosion of reinforcing mesh in concrete structures, when exposed to chlorides, is a common occurrence. It is a complex phenomenon related to structural, physical, chemical and environmental considerations. It can have a catastrophic effect on the viability of the structure.
Steel placed in concrete is inherently protected by both the alkaline and dense nature of concrete. When cracking occurs and especially where there is flowing water, both of these mechanisms are compromised. As free lime washes out, the substrate tends toward the acid end of the pH scale. Also the increased porosity allows the ingression of a broad range of undesirable environmental factors.
Crystalfix is a migratory chloride inhibitor in that it helps exclude chlorides by densification of the substrate. Because it generates insoluble lime crystals, the chemical nature of the crystal growth again restores the inherent alkalinity to the substrate.
In a nutshell, Crystalfix offers both physical and chemical protection of steel reinforcing. This protection occurs when using Crystalfix on or adjacent to steel reinforcing. Also, because of its densification properties, Crystalfix can facilitate a reduced concrete cover over steel reinforcing at the point of manufacture.
