Abstract
In both the energy demand and the carbon footprint of fired-clay bricks, firing is the most influential factor. This study evaluates biomass fly ash (BFA) as a partial clay replacement (0, 10, 20 and 30 wt%) in extruded bricks fired at 500, 600 and 900 °C. Mineralogical (XRD), thermal (TGA/DTG) and microstructural (SEM) analyses were combined with mechanical and physical testing, together with an attributional life cycle impact assessment, with environmental results additionally normalized by compressive strength. BFA promoted earlier phyllosilicate dehydroxylation and hematite crystallisation at lower temperatures; however, its fluxing contribution to densification was limited and strongly temperature-dependent, as at 500 °C it behaved as an inert filler and only from 600 °C did it promote partial densification. The maximum compressive strength was reached with 20 wt% at 600 °C (8.6 MPa) and with 10 wt% at 900 °C (12.3 MPa), 30% higher than the control. Although BFA slightly increased process-related CO₂ emissions, firing energy was, as expected, the governing factor of the environmental impacts. The combination of 20 wt% BFA and firing at 600 °C offered the best balance between mechanical performance and environmental sustainability, supporting the use of BFA as a viable secondary raw material for lower-carbon ceramic bricks.
