Effects of coal clinkers on physical and mechanical properties of the briquettes

This study was carried out to investigate the effect of coal clinker used in briquette production on physical and mechanical properties of briquettes. To do this, seven briquette classes were formed by changing the volume of coal clinker and all-in aggregates and porous briquettes were produced for each class according to Turkish Codex no. 406 (TS 406) and tested. Increasing ratio of coal clinker volume affected the compressive strength and water absorption of the briquettes negatively. As for the dimensional changes, bulk densities, losses due to freezing-thawing, and heat conductivity decreased and were af-fected positively. It was concluded that coal clinkers might be used in briquette production in certain ratio to make them profitable and lessen their adverse effects on the environment.
