Carolina Refractories manufactures, stocks, and supplies the two general classes of mortars used in the refractory industry. Our current list of CAROBOND mortar is made from both classes, Air-setting (wet and dry) and Heat-setting (wet and dry) are used with refractory brick to fill in joints and create a bond between brick.  All Carolina Refractories wet setting mortars come in 60 lbs. pails while our dry-setting mortars come packaged in poly-lined bags. Within the two classes of mortars there are 3 types: Fireclay, High-Alumina, and basic Mortars.   


Fireclay mortars are used most predominately when laying insulating fire brick as well as high alumina brick.  They work well in medium temperatures and overall a well-rounded product to lay blast furnace brick.  Carolina Refractories offers a variety of fireclay mortars in both dry and wet mixes. 


High-Alumina Mortars are used specifically in extremely high temperature refractory applications.  Included in this category are Phosphate-bonded mortars which have high refractoriness.  This type of mortar is used with High-Alumina brick. 


Often used with Basic Brick, Basic mortar has excellent resistance to corrosion in many refractory applications.  Basic mortar can be used with all four types of brick and can also provide the final bond between regular firebrick and acid proof brick.
