CLEVA-Crete admixtures are not the same as an AS 3799—1998, liquid membrane-forming curing compounds.
When an AS 3799—1998. liquid membrane-forming curing compound is specified for concrete, CLEVA-Crete would recommend that you use one.
A combinations of high temperatures, winds and low humidity would require placement planning that include ‘hot weather’ considerations with concrete placement and finishing.
Whilst in optimal weather circumstances, the answer to this question may be no, we recommend all standard procedures for pouring in cold weather and for pouring in hot windy weather as advised by Cement Concrete & Aggregates Australia, should be adhered to.
This means that many concrete finishers will choose to use a curing agent or simply keep the top surface wet till sundown at such times.
In normal temperatures and when it’s not a windy day, CLEVA-Crete doesn’t normally require any kind of curing agent on top because it cures the concrete from the inside out. If it’s not a 35° day with high and low relative humidity, it fares very well.
As far as densifiers, CLEVA-Crete is one of the best densifiers available. As it creates masses of nano sized particles of a very pure amorphous style calcium silicate hydrate gel it goes very hard after about two months, so these are not normally required.
