Retardant admixtures for concrete

These additives reduce the curing speed of the concrete, that is, increase its setting time. It is common to use it in hot weather, in situations when concrete is manufactured outside the construction site and the transport and placement of concrete can take longer than usual. Its use has a number of benefits, such as the reduction of cracks in concrete, greater ease in density and viability, as well as reducing the permeability of concrete.
