Influence of Wastes and Synthesis Conditions on the Compressive Strength, Setting Time and Gels of Waste-Based Geopolymers

Gels
In civil engineering, both rapid setting and delayed setting are needed for various application scenarios. In order to regulate the setting time of concrete, the iron ore tailings-blast furnace slag (IOT-BFS)-based geopolymers were synthesized with a ...

Metakaolin based geopolymer concrete with recycled geopolymer concrete dust

, 2022
Mechanical analyzes were carried out on the recycled concrete samples obtained by preparing different mixtures of geopolymer powder, metakaolin, aggregates and alkali activator as sodium silicate (Na2SO3) and sodium hydroxide (NaOH) solution, which were formed by grinding the geopolymer concrete samples prepared with certain temperature and low curing ...
