The study conducted by a team of researchers explores the innovative use of wood waste ashes (WWA) in geopolymer mortar and concrete products utilizing Norway's abundant forest resources for sustainable building materials.
Despite Norway's extensive forests, its bioenergy sector has lagged due to reliance on hydropower. Plans aim to boost biomass utilization by 70%, leveraging a potential forest fuel supply of 20 to 27 TWh·year-1 and enhancing forestry practices. Interest is growing in using wood waste ash (WWA) in geopolymer products, tapping into Norway's forest resources for sustainable building materials.
This study explores substituting WWAs in metakaolin and blast furnace slag-based geopolymers using advanced techniques like particle size, X-ray fluorescence, scanning electron microscopy, and AI-assisted analysis. Findings reveal high K2O ratios in WWA2_1 and WWA3, and a CaO ratio of 71.48 in WWA2_2, reducing the need for Na2O and K2O in precursors. The figure below showed the study process graphically.
Key findings include high K2O ratios in WWA2_1 and WWA3, and a CaO ratio of 71.48 in WWA2_2, which reduce the need for additional Na2O and K2O in precursors. WWAs demonstrate potential as fine aggregate, altering the Si to other element ratios, and providing hybrid cementitious functions functions in geopolymer mortar, leading to environmentally friendly and aesthetically viable construction materials.
