Thermal stability and mechanic al properties of alkaline activated mortars synthesized from POFA after exposure to elevated temperatures
الملخص
This paper presents results from experimental studies on the Thermal stability and mechanical properties of alkaline-activated mortars, which that prepared by alkaline solution activating POFA.The compressive strength test and characterization, employing XRD and, FESEM were conducted on geopolymer mortar specimens at ambient temperature and after exposure to elevated temperatures from 200℃ - 1000°C. Results from these tests show that geopolymer mortar exhibits higher temperature-induced degradation in compressive strength and body at1000°C. the mixture of POFA experienced no thermal cracks, its deformation occurred at 1000℃ which resulted in extensive shape changes. measure the compressive strength of the exposed alkaline-activated mortars. The relative residual compressive load for the mixture (a) decreased from 77% to 40% after exposure to temperatures from 200°C to 800°C
