Abstract

The purpose of this paper is to investigate on hydration, setting time and compressive strength properties of cement paste mixed alkali-free accelerator using aluminum sulfate for shotcrete. The experimental focus is to variouse added element with alkali-free accelerator for shotcrete using aluminum sulfate. When diethanolamine was used as a component of alkali-free accelerator, alkali-free accelerator contributed to increasing early hydration, setting time and compressive strength properties of cement paste and mortar.
