Hydraulic Refractory Mortars – Specially-Engineered Blend

Hydraulic refractory mortar is a specially-engineered blend of specific cements and aggregates that gives the mortar unique heat-resistance and thermal characteristics for use in high-temperature applications. They are such as chimneys, fire pits, barbeques, and pizza ovens.

Main 4 Features Of Refractory Mortar

  • To be called a medium-duty Castable Refractory Mortar, the product must pass the ASTM C-199 (American Society for Testing and Materials) testing standards for mortar temperature limits.
  • Regular mortars can generally reach temperatures up to 600°F.
  • However, a medium-duty refractory mortar has been lab tested to resist 2,550°F for a minimum of 6 hours without melting out of the joints of a firebrick and refractory mortars assembly.
  • Additionally, medium-duty refractory mortars are required by most building codes for the installation of firebrick and flues in chimneys, masonry fireplaces, and similar applications.
