WebbConcrete retarder is a chemical that slows down the hardening process of concrete. This can be helpful in a few different ways: It allows concrete to remain workable for a longer period of time, which can be helpful in hot weather or when working on large projects. It can prevent the formation of cracks or seams between different pours of concrete. WebbACI (American Concrete Institute) and pay attention to the instructions in the trade manual [5]. One of the added ingredients in concrete is a Retarder (a chemical to slow the process of bonding concrete mixtures). Usually needed for concrete not made at concrete pouring sites. The process of binding the concrete mixture is about 1 hour. So if the
