Abstract
A cement composition including a dry phase and a liquid phase. The dry phase includes an aluminosilicate source, including amorphous bagasse ash with a concentration between 40 wt. % and 100 wt. % of the weight of the dry phase. The liquid phase includes at least one of water and an alkaline activator solution. The alkaline activator solution includes at least one of an alkali metal stearate, an alkali metal silicate, and an alkali metal hydroxide.
