Concrete Curing Compounds
Correct curing of concrete is essential in achieving maximum strength and durability of the finished concrete structure. Curing involves maintaining adequate water within the concrete mix while the cement hydration reaction occurs, to ensure it progresses as close as possible to completion.
Curing compounds are designed to minimise the loss of water during concrete cure, producing concrete which is free of cracks, has a dense stain-resistant surface, and has minimal porosity to prevent the ingress of water, chlorides, and other corrosive elements which will attack reinforcing steel.
AS3799 is the Australian Standard for "Liquid membrane-forming curing compounds for concrete", and stipulates a minimum moisture retention of 90% over a 72 hour period.
