Abstract:
A method of generating a combustion ash composition comprising the steps of:providing combustion ash having an amount of hydratable oxide; assessing said amount of hydratable oxide in said combustion ash; assessing a first amount of water to convert said amount of hydratable oxide to about five weight percent; combining at least said first amount of water with said combustion ash to generate a partially hydrated combustion ash; converting said amount of hydratable oxide to about five weight percent; expanding said partially hydrated combustion ash to a first molar expansion volume; allowing said partially hydrated combustion ash to heat as a result of exothermic hydration of said hydratable oxides; permitting evaporation or a portion of said first amount of water from said partially hydrated combustion ash; assessing a second amount of water to convert substantially all of the remaining hydratable oxide to hydroxide; and adding at least said second amount of water to said partially hydrated combustion ash to generate a combined material.
