The expansion of the construction sector has contributed to depletion raw materials and an increased demand for resources; therefore, sustainable approaches are required satisfy demand. present study explores development geopolymers by utilizing industrial by-products from mining, ceramics, olive oil production, steel manufacturing. Specifically, slate stone cutting sludge (SSCS) chamotte (CH) used as aluminosilicate precursors, with biomass bottom ash (OSBA) acting alkaline activator, along sodium silicate, granulated slag (SGS) incorporated aggregate. Novel were prepared consistent proportions SSCS OSBA while varying CH content 10 2 wt.%. SGS proportion was adjusted 35 50 wt.%, different Na2SiO3/OSBA ratios (0.35, 0.31, 0.19, 0.08) examined. To identify optimal mix, a series physical mechanical tests conducted, complemented FTIR SEM analysis evaluate chemical microstructural changes. best-performing formulation achieved compressive strength 42.8 MPa after 28 days curing. identified quartz carbonate phases, suggesting that did not fully dissolve carbonates formed during heating process. examination mixture indicated incorporation (up 45 wt.%) facilitated creation compact, low-porosity structure. EDX results revealed presence Ca-, Na-, Si-, Al-, K-enriched supporting formation (N, C)-A-S-H gel networks. These demonstrate potential SSCS, CH, OSBA, create geopolymer concretes, showcasing viability using eco-friendly substitutes traditional materials.
