INCINERATOR FLY ASH GEOPOLYMER AND METHOD

摘要

A geopolymer concrete formed by mixing about 3% to about 43% by weight incinerator fly ash, about 3% to about 35% by weight coal fly ash, about 7% to about 38% by weight alkaline activator liquid, and about 31 % to about 70% by weight aggregate. The incinerator fly ash may be derived from a solid waste incinerator facility. The alkaline activator liquid may include a sodium hydroxide solution and sodium silicate. The aggregate may include a fine aggregate, such as sand, and a coarse aggregate, such as gravel.
