The reuse of by-products as alternative raw materials to traditional construction is required in order ensure sustainable development the sector and a significant important focus fields science. This study developed geopolymers using from mining, ceramics, olive industries, including slate stone cutting sludge (SSCS) chamotte (CH) aluminosilicate sources, biomass bottom ash (OSBA) an alkaline activator with sodium silicate. A key novelty research lies use SSCS, underexplored by-product geopolymerization studies, viable source. were prepared varying weight ratios CH, OSBA/Na₂SiO₃ (1.7, 1.9, 2.2, 2.4). Physical mechanical tests determined optimal formulation, while FTIR SEM analyses revealed material’s chemical structural evolution. analysis detected quartz carbonate phases, indicating incomplete dissolution formation during calcination. dense microstructure reduced porosity enhanced samples higher OSBA content. geopolymer (60% OSBA, 30% ratio 2.2) achieved compressive strength 33.1 MPa after 28 days. These findings demonstrate feasibility producing promoting industrial alternatives conventional binders.

Study of Properties of Novel Geopolymers Prepared with Slate Stone Cutting Sludge and Activated with Olive Stone Bottom Ash

Materials, Journal Year: 2025, Volume and Issue: 18(8), P. 1774 - 1774

Published: April 13, 2025

The sustainable development of building materials is based on reusing by-products to reduce environmental impact and promote alternatives traditional materials. In this study, geopolymers were developed from the mining, ceramic, thermal industries: slate stone cutting sludge (SSCS) chamotte (CH) as aluminosilicate sources, olive bottom ash (OSBA) an alkaline activator, combined with sodium silicate (Na2SiO3). Eight geopolymer families prepared constant amounts SSCS CH varying proportions OSBA/Na2SiO3 (0.88–1.31). evaluation phase included physical, chemical, mechanical, microstructural tests. results showed that optimum formulation (GP E) contained 25% SSCS, 15% CH, 19% OSBA a Na2SiO3/OSBA ratio 1.0, achieving compressive strength 24.12 MPa after 28 days curing. GP E also lowest porosity (19.54%), minimal water absorption (6.86%), favorable conductivity (0.688 W/mK). Fourier transform infrared spectroscopy (FTIR) scanning electron microscopy (SEM) confirmed formation dense homogeneous matrices. These demonstrate feasibility manufacturing using substitutes for binders, promoting practices, industrial by-products, reducing carbon emissions in construction.
