Abstract:Burning wood is estimated to produce about 6–10% of ash. Despite the possibility of recycling wood ash (WA), approximately 70% of the wood ash generated is landfilled, causing costs as well as environmental pollution. This study aims to recycle WA in an alternative way by inserting it as filler in geopolymeric materials. Here, metakaolin, NaOH, sodium silicate, and WA are used to realize geopolymers. Geopolymers without and with 10, 20 and 30% of WA are synthesized and characterized after 7, 14, 28 and 56 days… Show more
“…Gómez-Casero et al 11 conducted a study on metakaolin-based geopolymers and found that the metakaolin-based geopolymers exhibit excellent compressive strength and thermal insulation performance, with lower thermal conductivity compared to PC. Catauro et al 12 investigated the structural stability of metakaolin-based geopolymers with and without the addition of fly ash and observed that the composite materials exhibited excellent durability and comparable compressive strength to PC. Siyal et al 13 compiled the research on the adsorption of heavy metals and dyes by geopolymers and found that geopolymers possess favorable surface properties and microstructure that enable highly efficient adsorption of heavy metal ions and dyes, exhibiting spontaneous adsorption behavior.…”
Molecular dynamics simulations were used to study the micro-reaction behavior of geopolymers and to explore the induction process and structural evolution of the initial stages.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
