Effect of Heating Temperature on the Properties of Low-Cement Heat Resistant Composites
Original language description
This study deals with a utilization of super reactive alumina (RA) and boehmite powder (BP) as a partial replacement of calcium aluminate cement (CAC) in refractory composites. These substitutes would have a positive effect on environmental performance of heat-resistant composites, specifically on reducing non-renewable resources consumption, CO2 emissions and on overall performance of the resulting composites as well. In order to study their properties, five mixtures were chosen with different ratio of substitutions of CAC. Mechanical properties (compressive strength, bending strength and dynamic modulus of elasticity) of CAC composites with the above mentioned supplementary materials were focused on. CAC is a primary binder for high temperature application, and therefore the measured properties were determined also after exposure to 400 °C, 1000 °C and 1400 °C. Both admixtures helped to reach better bending and compressive strength than the reference mixture without a replacement of CAC. It was proved that the replacement of CAC with 11.3% RA and 3.8% BP is the optimum combination which significantly improves the properties of the composite and is the most usable for further applications.
