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.
