Measuring geopolymer set times under ionizing radiation - advances in instruments and procedures
Апстракт
Geopolymers are a class of alkali activated binders, and present a viable alternative to Portland cement. Utilization of geopolymers is a way to reduce greenhouse gas emissions and utilize secondary materials.Geopolymers are becoming a material of choice in radioactive waste conditioning, for grouting and encapsulation. Binder set times are a key parameter in determining the workability of grouts, mortars and concrete. While studying the effects of ionizing radiation on geopolymer set times, we were constrained by the configuration of the irradiation device and field, so we developed a modified Vicat apparatus, sample case/phantom, and temperature/humidity monitor. The modified procedure has allowed for a better temporal resolution of the measurements, with continuous monitoring of the experimental conditions. Fly-ash geopolymer set times under Co-60 gamma radiation are presented.
