Investigation of concrete component and size effect on electrical curing method

In this study, the effect of concrete's component and size on electrical curing method is investigated. To examine the effect of dosage, 250, 300, 350 and 400 dosage and 10 x 10 x 35 cm sized concretes are produced. 0, 40, 60, 80 and 100 V stress intensity are respectively applied on produced concretes at stable frequency by AC power supply. Electrical current with different frequencies are applied on some series at stable frequency stress intensity. Concretes which have different water/cement ratios are produced. It has been researched if accelerated cure can be done on concrete by comparing setting time, porosity, water absorption, compressive strength, etc. of concretes which have current application with the ones which don't have current application. DC and AC current application on concrete can be made in terms of accelerated cure. Because of DC current's polarization effect, AC power supply is used in the experiments. Consequently, accelerated cure can be done by applying AC current without having any compressive strength decline under certain stress intensity. Through the application of 100 V stress intensity to the 250, 300, 350 and 400 dosage concretes, their final setting times are shortened 510, 380, 410 and 500 minutes, respectively when they are compared to the same dosage reference concretes. Scanning Electron Microscope (SEM) views of 300 dosage concretes are investigated and it is determined that hydration reactions accelerate as stress intensity increases from 0 V to 100 V.
