The conditions prevailing during the curing process also influence visual aspects, including the prevention of efflorescence and unwanted color variations caused by humidity and temperature differences in the curing rack. The required dwelling time in the rack is another factor that determines the time to further finishing of the concrete products (such as tumbling, blasting or grinding) or the dimensions of the curing racks.
