Özet

Concrete’s gaining strength at an early time and it’s being used immediately are the results of developing industry. Through applying different methods, concrete gains early strength. Accelerated curing method through applying electrical stress is one of the main curing techniques. In this study, the relations between setting time and stress intensity as a result of applying 7.5 V, 15 V, 22.5 V stress to 250 dosaged cement-based mortars at 5 x 5 x 10, 5 x 5 x 15, 5 x 5 x 20, 5 x 5 x 25 (cm x cm x cm) sizes have been investigated. Through measuring the temperature of the specimens to which stress has been applied in every 2 minutes, relation between temperature and setting time has been established. Moreover, the porosities of specimens to which stress has been applied and to which stress hasn’t been applied have been compared. It has been concluded that setting time can be shortened and porosity can be decreased as a result of applying electrical current to mortars.
