ABSTRACT

This study aimed to lower the hydration temperatures of the cement-based mortars by replacing the cement with glass fiber (FG) at 0%, 0.5%, 1%, and 2% ratios. The effects of nano zinc oxide (ZnO-0.25%) and FG (1%) were also investigated when used together. The temperatures of the mortar samples were monitored at one-minute intervals using temperature sensors positioned at the midpoint of each sample. It was concluded that both ZnO and FG delayed the setting time by reducing the mortar's internal temperature. It was evaluated that FG was more effective than ZnO in reducing the hydration temperature. In the specific test series, an alternating current (AC) was applied to the fresh mortars for one day, utilizing an AC power source to accelerate the hydration reactions. The co-addition of FG-ZnO to the mortars and application of AC resulted in 12 ℃ increases in internal temperatures. Increasing the FG ratio in the mortar resulted in a higher mechanical strength. Another result obtained from the research was that applying AC to mortar (containing FG-ZnO) resulted in an approximate 60.95% increase in compressive strength.
