Effect of Sodium Aluminate Dosage as a Solid Alkaline
· Extensive research into alkali-activated slag as a green gel material to substitute for cement has been done because of the advantages of low-carbon dioxide emissions and recycling of industrial solid waste. Alkali-activated slag usually has good mechanical properties but the too fast setting time restricted its application and promotion. Changing the composition of alkaline activator could
