Enhancing the properties of geopolymer concrete using nano-silica and microstructure assessment: a sustainable approach

Scientific Reports, 2023
Nowadays low calcium fly ash-based geopolymer concrete can be replaced with cement-based concrete to avoid the adverse effect of manufacturing cement on the environment. Utilization of geopolymer concrete instead of traditional concrete using low calcium

Rockwool waste in fly ash geopolymer composites [PDF]

Journal of Material Cycles and Waste Management, 2016
Mineral wool waste is often considered unrecyclable, due to its difficult-to-process physical composition, and potential microbial contamination in the post-consumer products. Total mineral wool waste generated in the EU is growing continuously and is currently over 2.3 Mt annually, volumetrically accounting for the largest single waste source in some ...

Extensive reuse of soda-lime waste glass in fly ash-based geopolymers [PDF]

, 2018
The possibility of extensive incorporation of soda-lime waste glass in the synthesis of fly ash-based geopolymers was investigated. Using waste glass as silica supplier avoids the use of water glass solution as chemical activator.
