چکیده
The purpose of this research was to evaluate the possibility using gold mine waste rocks (GMWRs) as alternative raw material for manufacturing fired bricks. feasibility study assessed through (i) physical, chemical, mineralogical and environmental characteristics GMWRs; (ii) determination natural clay (NC) substitution effect when (iii) firing temperature on mechanical physical properties Five mixtures NC GMWRs were studied. percentages with varied from 0 100%. brick specimens at 900 °C, 1000 °C 1050 °C. results show that increasing improved flexural strength density bricks, while caused a reduction in resistance bricks an increase their porosity and, consequently, water absorption rate. However, contained up 80 wt% satisfied requirements set by applicable civil engineering standards. This found be efficient sustainable solution mitigate hazards better manage mining wastes, concurrently producing marketable products them, which is accordance circular economy concept.
