What type of mortar do you use for fire brick?

Mortar the Firebrick Firebrick is mortared with refractory cement, which, unlike regular masonry mortar, can withstand high heat.

Will red bricks explode in a fire pit?

The fact that bricks and CMUs are so porous also aids in the drying when exposed to heat like a fire. … If the pressure is great enough, the block will crack, pop or in some cases explode. But since the CMUs are so porous, they typically release the steam as it’s being made by the fire.
