RISInfluence of Process Variables on Shrinkage in Low-Calcium Fly-Ash Geopolymers
Publisher: American Society of Civil Engineers
Abstract: The influence of process variables such as curing temperature and relative humidity (RH) on the shrinkage of alkali-activated fly ash (AAF) is examined in this work. The ambient conditions are varied after an initial ...
High-Temperature Performance of Low-Calcium Fly Ash–Based Geopolymers
Publisher: ASCE
Abstract: The high-temperature behavior of alkali-activated fly ash (AAF) geopolymers is evaluated. The physical and phase changes in the material are determined to be a function of temperature of exposure. Thermal diffusivity and ...
