Fabrication of geopolymer bricks using ceramic dust waste
HighlightsGeopolymber bricks were prepared using fine cyclone waste from wall tile industry.Compressive strength increased with degree of polymerization.Water absorption of bricks generally increase with both curing time and temperature.A mix of dust with 10% Ca(OH)2, 1% NaOH resulted in compressive strength of about 9MPa.
AbstractThe fine dust waste from the cyclones connected to the spray dryer in ceramic tiles manufacture was used in the preparation of geopolymer bricks. Dust was characterized after firing using XRD, XRF, PSD, and its bulk density was determined. Caustic soda was used at 1% NaOH level together with slaked lime at Ca(OH)2 percentage ranging from 6 to 10%. These were mixed with the fine dust waste and molded to form geopolymer bricks. The properties of produced bricks were studied after 28days. Results indicated that the 28days compressive strength increased with the degree of geopolymerization. It was found that the results abide by the Standard ASTM C 62/2013 for a recipe consisting of 1% NaOH, 10% Ca(OH)2 and 38% water. The results were confirmed by SEM imaging.The use of waste raw materials (except for caustic soda) resulted in a substantial reduction in the estimated production cost of the bricks.
