PZB 4 1600 °C

This combined corundum refractory concrete with a silicon carbide admixture and a hydraulic bond resists shocks and abrasions well. Shaped blocks made from this material are suitable for places with sudden temperature changes. For long-term loads, we recommend a maximum temperature of 1600 °C. However, in the short term this material can handle temperatures up to even 1800 °C.
