Companies and trade organizations with expertise in concrete construction technology are familiar with options available for corrosion protection in new or rehabilitated structures. With support from these experts, each end user should determine whether or not application of chloride-based deicers is appropriate for their given situation.
The chloride ions in MELT Calcium Chloride Crystals can permeate porous concrete. When chloride, oxygen and moisture come together on the surface of unprotected steel reinforcement (rebar) embedded in concrete, corrosion will result. Rust formation on rebar places pressure on the concrete that can result in cracking, spalling and delamination. The loss of bond between concrete and reinforcing steel and the loss of rebar cross-sectional area both have the potential to result in serious structural problems.
