Abstract
The development of various non-destructive measurements involves study on the microstructure evolution of cement-based materials. Electrical resistivity measurement is a method that can monitor microstructure evolution due to change in resistivity through hydration products by filling pore space. This study aims to measure electrical resistivity in order to investigate an affect of various environmental condition. A same mix-proportion mortar sample are prepared to study the effect of curing various temperature and various humidty. As a result, the rising time, which is the onset of an increase in electrical resistivity, is shorten and the increasing ratio of electrical resistivity is increased at higher curing temperature, but various humidity are not significant effect.
