MAKING FOAMED CONCRETES FROM FLY ASH BASED ON GEOPOLYMER METHOD

摘要

The foamed concretes which have useful characteristics for modern technique and constructions have been widely interested. The article presents the first results on the manufacture of foamed concretes from fly ash based on Geopolymer method combined with foam creation by H_2O_2. Some of the concrete's properties such as density, heat-resistance characters, and compressive strength were compared with traditional lightweight concretes. Especially when the foamed concretes were synthesized form fly ash by Geopolymer method, the heat-resistance of product could be as high as 1000℃.
