The effect of alumina fiber on the high-temperature resistance and mechanical properties of aluminate cement
The experiment aimed to improve the refractoriness of calcium aluminate cement by adding alumina fibers in vary-ing amounts(0.1％,0.2％,0.3％,and 0.4％).The analysis results indicate:the mechanical properties of the samples at room tempera-ture improve with increasing calcination temperature;the optimal addition amount of alumina fibers is 0.3％,yielding the best me-chanical properties and minimal linear change rate;phase composition and microstructure analysis show that TiO2 can lower the for-mation temperature of CA6,promoting the formation of larger and thicker hexagonal plates,thereby enhancing the structural refrac-toriness and strength.
