Unconventional Trend in Adopting the New "One-Part" Mixture Geopolymer for Construction Applications

Year: 2025

Type: article

Abstract: The work aimed at producing “one-part” geopolymer composite material using coal fly ash and granulated blast furnace slag as alumina-silicate precursors, sodium carbonate as a solid alkali activator, and sodium lignosulphonate as a water-reducer superplasticizer, constituting a dry powder mixture, to which water was added later. This preparing way of the geopolymer is an alternative version to the traditional “two-part” geopolymer using liquid alkaline activation and is mainly suitable for in-situ construction applications. The results of the current experiment showed good thermal insulation properties, the density and heat conductivity values being quite low as well as quite high levels of compression and flexural strength, early strength values after only 7 days being high considering the final mechanical resistance values after 28 days.
