Microstructural and non-destructive investigation of the effect of high temperature exposure on ground ferronickel slag blended fly ash geopolymer mortars

It is important to understand the high temperature response of a newly developed construction material in order to assess the effect of fire exposures. The effects of different percentages of ground ferronickel slag with fly ash and different temperature exposures on geopolymer mortars were evaluated by the changes in mass, cracking behaviour, compressive strength, microstructure and ultrasonic pulse velocity after exposure to temperatures up to...
