14. CONCLUSION It is false economy to neglect the correct curing program for all concrete items produced either on site or in factory processes. 2- Most pre-cast concrete producers employ some sort of curing system that is appropriate to their production regime. 3- Most reinforced concrete constructors pay scant regard to this …
Microwave has been studied for quickening curing form for the repair of cement mortar and freshly cast concrete. Microwave heating was adopted by researchers to increase the early strength for newly poured concrete [86].Recent investigations on mortar repairing showed that in a short heating time, the microwave heating of concrete could …
Membrane curing: Apply a membrane-forming curing compound to the concrete surface, which creates a barrier that retains moisture and promotes proper hydration. Wet curing: Keep the concrete surface continuously wet using techniques like spraying, ponding, or using water-soaked materials, ensuring moisture remains available …
Furthermore, curing concrete at low temperatures slows down the cement hydration rate compared with curing at high temperatures. Several researchers reported that concrete cured at temperatures below 23 °C is (Kosmatka et al., 2002) unfavorable for the development of early strength (Kjellsen and Detwiler, 1992).The increase in curing …
Early-age cracking during the plastic stage is unsightly and a cause of future durability problems. This paper investigates the effects of various simple curing methods used in practice to enhance early-age concrete cracking performance, including covering concrete with a plastic sheet and wet hessian fabric, surface power floating and use of …
