Abstract
Curing is a process during which concrete containing hydraulic cement will be hardened over time, as the result of hydration of cement in the presence of sufficient amounts of water and heat. Roller compacted concrete (RCC) is a no slump concrete with no bleeding water. Due to the large expose surface of RCC pavements, the water evaporates quickly from its surface and causes drying cracks and deterioration. In this regard the curing process (time and type of curing) is very important for the Roller compacted concrete pavements (RCCP). In this work a membrane forming curing compound was used for curing RCCP specimens produced by two different mix designs. Moreover abrasion resistance of them was compared with the specimens cured by water or without curing. Based on the results, the moist curing and the curing with membrane forming compounds decreased abrasion of RCCP specimens up to 10 and 7 percent, respectively.
