Abstract: In this paper development of porous ash primarily based geopolymer with low thermal conductivity. Porous ash-based geopolymer material was created exploitation ash and metal water glass as original material and H2O2 as foaming agent. The development of sustainable construction and construction materials with reduced environmental footprint in each producing and operational phases of the fabric lifecycle is attracting increased interest within the housing and industry worldwide. Within the future the area of development of fiber reinforced cement free fly ash primarily based geopolymer concrete will be using by treated natural fibre and synthetic fiber.

Keywords: Geopolymer, Fiber Reinforced Concrete.
