Optimization of mix proportions and mechanical properties of coal gangue-based multi-solid-waste geopolymer mortars

Case Studies in Construction Materials
To address the challenges of high production, large stockpiles, and low utilization of coal-based solid waste, a coal gangue-based geopolymer was developed using coal gangue powder, ground granulated blast furnace slag (GGBFS), and fly ash as ...

PRODUCTION OF SODIUM CARBOXYMETHYLCELLULOSE FROM PINE WOOD WASTE AND INVESTIGATION OF ITS PHYSICOCHEMICAL PROPERTIES

SERIES CHEMISTRY AND TECHNOLOGY
With the increasing use of wood resources, wood waste disposal is becoming a more pressing issue. Wood waste can be effectively processed and reused, thus reducing environmental impact. Our study proposes using wood waste to produce sodium carboxymethyl cellulose (Na-CMC) with enhanced physical and chemical properties.
