Electrical curing application on cement-based mortar with different stress intensity

Abstract

In this study, the effects of different stress intensity on the electrical resistivity of hardening (setting) cement-based mortar were investigated. In experiments, four different mould (5 × 5 × 10 cm, 5 × 5 × 15 cm, 5 × 5 × 20 cm and 5 × 5 × 25 cm) were used. Different combinations of stress intensity (7.5, 15, 22.5 and 30 V) were used on mixtures. The measurements were done at room temperature. Electrical resistivity and setting time of the specimens with and without electric current application were also investigated. Moreover, specific setting hydration temperature was measured by using thermocouple. As a result, electric current application can be used for obtaining to rapid setting time on the mortar with high volume stress intensity.
