Experimental Study of Applying Steam and Microwave Technology for Fresh Concrete Curing
In this study, cement mortar and concrete were used to investigate some accelerated curing on the strength and chloride electrical penetration of concrete. To evaluate some rapid testing procedures that could run a series of tests within one day to attain an estimate of the 28-day strength of the concrete, specimens with microwave heating in different hydration stages were tested on compressive strength and chloride electrical penetration. The initial result was that the accelerated curing on fresh mortar or concrete samples that combines steam curing and microwave heating could increase strength successfully within one day. Some accelerated curing samples could reach 7-day compressive strength, and the others could reach 28-day compressive strength. It was found that the 28-day chloride electrical penetrability of the accelerated curing samples reduce greatly when curing them in water after the accelerated curing. This contributes to the denseness of microstructure and reduces the chloride electrical penetrability. The steam and microwave techniques could provide the advantage of quick and uniform heating for curing of cement mortar and concrete.
