Thermal fatigue behaviour of a Kenyan kaolinite clay

Abstract

The thermal fatigue resistance for a Kaolinite clay-based refractory used for then1lfl1 insulation in local (Kenyan) firewood cooking stoves has been studied by subjecting them to a water quench to predict their values for a stress-corrosive environment. Plots of speed of utrasonic pressure waves versus thermal shock severity and those of flexural strength versus thermal shock severity show retention of strength up to severi 'ties of about 480'c which is good for refractory materials
