Considering the increasing demand for the strength and high-temperature performance of refractory products during application, refractory products, especially refractory bricks, are developing towards densification, long dimensions, and large-scale. Correspondingly, high-pressure forming and high-temperature firing technologies are also constantly developing.
And ceramic aggregate concrete, as a new type of building material, has been widely used in various buildings. Ceramic aggregate concrete integrates insulation, seismic resistance, frost resistance, fire resistance, and other properties, especially its fire resistance is more than four times that of ordinary concrete. For the same fire resistance period, the thickness of the ceramic aggregate concrete board is 20% thinner than that of ordinary concrete.
In addition, fly ash ceramic particles can also be used to prepare refractory concrete with a fire resistance below 1200 degree . At a high temperature of 650 degree , ceramic aggregate concrete can maintain 85% of its strength at room temperature. Ordinary concrete can only maintain 35% to 75% of its strength at room temperature.
