Will deicing with calcium chloride products damage my concrete?

OxyChem calcium chloride products are recommended for deicing asphalt and concrete surfaces that have been designed and constructed for winter weather conditions and deicer usage.

OxyChem calcium chloride products will not chemically attack asphalt or concrete. Melt water from the deicing process may soak into porous concrete and re-freeze, creating pressure within the concrete structure. Concrete that lacks the strength to withstand this pressure may spall or scale. Concrete is resistant to scaling damage if it is air-entrained, mixed, placed and cured according to the recommendations of the American Concrete Institute Committee 201.

OxyChem calcium chloride products are not recommended for deicing concrete that is less than one year old, precast steps, masonry (stone, brick, mortar joints), or existing concrete that has exposed aggregate, is precast, prestressed, chipped, cracked, spalled or weathered.
