Abstract
This paper aims to investigate the influence of coal fly ash containing ammonium salts on properties of cement paste. Fly ash was incorporated at percentage of 20% by weight of the total binder to replace Portland cement. Ammonium hydrogen sulfate (NH3HSO4) or ammonium sulfate ((NH3)2SO4) were introduced at percentages of 3.0%-6.0% or 1.5%-3.0% by fly ash weight. Compressive strength, setting time and hydration heat were evaluated on variable...
