Popis:	This paper studies the finding density and morphology analysis of geopolymer bricks using bottom ash and fly ash as a geopolymer raw material. The study has been conducted to produce bottom ash and fly ash geopolymer bricks by varying the ratio of fly ash/bottom ash, ratio solid/liquid and ratio sodium silicate (Na2SiO3)/ sodium hydroxide (NaOH) in the mix design. The compressive strength range between 3.8-4.5 Mpa was obtained in theprevious study [9]. The density and morphology analysis are done based on the optimum ratio selected from bottom ash/fly ash, solid/liquidand Na2SiO3/NaOH which is 1:2, 2.0 and 4.0 respectively for non-loading application brick. The morphology analysis of the bricks is closely related to the density recorded. The highest density shows the highest value of compressive strength and a denser microstructure of morphology.
