Deicing Products > Commercial > Cryotech CMA®
Many engineers specify CMA because it does not chemically attack concrete nor does it increase spalling caused by the freeze-thaw cycling of water. A U.K. Department of Transport study concludes: "With the exception of CMA, all of the deicing chemicals tested resulted in a greater deterioration of the concrete than water alone...CMA was the only chemical on weak structural concrete which satisfied the criterion for scaling damage."
Testing by Michigan DOT confirmed that CMA dramatically reduced spalling in both air-entrained and non air-entrained concrete compared to salt alone. Blending small amounts of CMA (minimum 20% by weight) with sodium chloride resulted in a reduction in salt-induced concrete scaling.
