Abstract:The effect of curing compound application time after concrete finishing was examined in the study. Times of 30 minutes, 2 hours and 4 hours were considered and repeatability was evaluated with comparisons to a Phase I portion of the study. Scaling resistance varied with mix type and curing compound type. None of the curing compounds provided scaling resistance that approached that of wet room curing. The effectiveness of most curing compounds appeared tied to the surface condition of the concrete. The presence of bleed water varied with mix type and if bleed water was present, the effectiveness of the curing compounds were typically compromised. Polyalphamethylstyrene (PAMS) resin based curing compound appeared to be equally effective regardless of application time but this was not true for wax-based, linseed oil and acrylic curing compounds. Generally for these compounds 2 to 4 hours was needed for best results depending on cementitious additives.
