Castable Refractory Cement

Lightweight Castable Refractory Cement - 55lb Bag / Dry

Lightweight Castable Refractory cement - also known as Castable Refractory or Fireplace Cement, is a high-heat tolerant refractory material that is designed for castable refractory cement pizza ovens, fire pits and backyard forges.  Refractory cement is able to withstand temperatures in excess of 2500°, which is roughly 2x hotter than you will ever get your pizza oven.

Refractory cement is designed for THICK refractory applications like pizza oven construction, building a forge or even making your own fire bricks.  This product is NOT firebrick mortar.

Refractory cement for Cortile Barile Ovens and Mattone Cupola Ovens.

Castable refractory weights approximately 120lbs per cubic ft. and is shipped in a 55lb bag.

Add clean water (3/4 to 1 qt.) for each 10 lb. and mix thoroughly. No other additives required.

May be cast or troweled into place.

Refractory materials meet ASTM C-401 Class B.

Possesses cold crushing strength of approximately 1500 lbs. per. sq. inch.

Good for applications well over 2500°F.

Castable refractory cement should be cast no thinner than 1 1/2 to 2 inches thick.

Brand of refractory cement we send you will depend on your location / region.

Refractory cement is Non-Water Soluble in service - Safe for outdoor use!

NSF / Food Grade Refractory Cement

Refractory Cement Recipe - Unlike High-Temperature MORTAR that you can make with common and locally purchased materials... Refractory cement is NOT something you can make yourself with sand, cement, lime, etc...  No matter what you read on Google or watch on YouTube - if you make a refractory cement blend, it will fail.  Guaranteed!

Castable Refractory Cement is like regular 'ol cement... But it can withstand 2500°! Castable Refractory is used in the construction of our Mattone Cupola DIY Pizza Oven.
