EFFECTS OF TEMPERATURE, WIND AND HUMIDITY ON SELECTED CURING MEDIA

A portland cement concrete pavement should possess various qualities to be considered effective. Most important to the driving public is a smooth ride. But the pavement should also be durable and structurally sound, and should maintain surface qualities required for traffic safety with respect to skid resistance. Proper consolidation, finishing, and curing are of particular importance in the production of high quality concrete. This research study summarizes the results of two laboratory studies and one field study conducted to investigate the curing component in producing high quality concrete pavements. The following conclusions were reached: 1) All of the curing methods considered (involving the use of some curing compound) proved to be effective. 2) In these tests the water soluble linseed oil curing compound (WSLO) was as effective as the white pigmented compound (WPC) in retaining moisture in the concrete. 3) Consistently, both WPC and WSLO tended to retain moisture more effectively than monomolicular film followed by white pigmented curing compound (MMF + WPC). 4) Applying MMF in two small applications instead of one large single application retained moisture more effectively except at low relative humidities. 5) Evaporation rates measured experimentally do not give the same trends indicated by the Portland Cement Association (PCA) chart. 6) The results of this research program indicate that the use of monomolecular film during construction could be valuable in gaining time before final finishing of the surface.
