Heat resistant concrete, also known as refractory concrete, is a special concrete that can withstand high temperature for a long time (above 200 ℃) and maintain the required physical properties at high temperature. FEATURE - The fire resistance is almost the same as that of refractory bricks of the same material - Fire resistant concrete is superior to low-temperature cementing agent, and has high compressive strength at room temperature. - The thermal stability is good. - The production process is simple and can be made into various precast blocks and mechanized construction Refractory concrete (castable) is mainly used for: - Bridge box girder counterweight (large and medium-sized highway and railway bridges - Building anti-floating counterweight (anti-floating counterweight of underground garage, sunken square, underground station, underground structure foundation of main podium commercial complex). - Mechanical counterweight and large counterweight components.
