STUDY OF FLY ASH GEOPOLYMER AND FLY ASH/SLAG GEOPOLYMER IN TERM OF PHYSICAL AND MECHANICAL PROPERTIES
This article presents the mixing parameters of fly ash geopolymer based on NaOH concentration (6M - 14M), S/L ratio (1.0 - 3.5), Na2SiO3/NaOH ratio (1.0 - 3.0) and ladle furnace slag replacement (10% -40%). Additionally, a comparative study between fly ash geopolymer and fly ash/slag geopolymer with...

| description | This article presents the mixing parameters of fly ash geopolymer based on NaOH concentration (6M - 14M), S/L ratio (1.0 - 3.5), Na2SiO3/NaOH ratio (1.0 - 3.0) and ladle furnace slag replacement (10% -40%). Additionally, a comparative study between fly ash geopolymer and fly ash/slag geopolymer with respect to the bulk density, water absorption, apparent porosity and compressive strength were investigated. The general bulk densities of fly ash/slag geopolymer were higher than fly ash geopolymer. The apparent porosity and water absorption of fly ash/slag geopolymers were comparatively lower than fly ash geopolymers. High compressive strength achieved by fly ash/slag geopolymer was contributed by high bulk density and low apparent porosity and water absorption. In other words, fly ash geopolymer obtained lower strength was due to lower bulk density and higher apparent porosity and water absorption. |
