No Cement Castables (NC)

Alumina based and bonded with a cement free binder improving performance in acidic environments. Standard alumina contents of 65, 90 and 95%. Example WAM 90 NC.

Silica Based with a standard silica content of 99%. Example WAM 99 VS NC.

 

Construction Grade Castables (CG)

Alumina based low cement bonded price competitive castable. Standard alumina contents of 50, 60, 70 and 80%. Example: WAM 50 CG.

 

Enhanced Matrix Castables (EMT)

Alumina based cement bonded similar to Standard Cement Castables but designed to reduce water demand       which improves workability and physical properties. Standard alumina content is 50, 60, 70, 80 and 95%.  Example: WAM®  70 EMT.

 

Lightweight Castables (LW)

There are two classifications of these products; a standard product and a low conductivity product (LK). Both provide insulation but the LK versions more so. Available densities of the standard product are 40, 50, 60, 70, 80, 90 and 100 PCF. A bubble alumina version is available in 90 PCF. There are gun versions as well. LK versions are available at densities of  25, 35, 40, 50, 60, 70, 80 and 90 PCF. Example: WAM 80-27 LW.

 

Gunning Mix Technology (G or RG)

These are non-lightweight alumina based compositions. The two versions of these products are a premium grade and a cost competitive Construction Grade (CG). Mixes base on a standard level of cement binder and a reduced level of cement binder are available. Premium Grade alumina contents available are 50, 60, 70, 80 and 95%. Construction Grade alumina contents available are 45, 50, 60, and 70%. Examples WAM 70 RG or  WAM 45 CG G.

 

Dry Mortars (M)

Alumina based dry mortars which are air set (AS) or heat set (HS). Air set mortars are available in alumina concentration ranges of 47, 50, 60, 70, 80, and 90%. Heat set mortars are available in alumina concentration ranges of 55, 65, 75, and 85%. In addition a heat set silicon carbide based mortar containing 75% SiC is available.   Examples: WAM 50 AS M or WAM 75 HS M or WAM SiC 75 HS M.

 

WFS Technology

Alumina based slurry mixes designed to be used with castable systmems employing  very high percentages of stainless steel wire fiber. Available alumina concentrations are 60, 90 and 97%. Example: WAM 60 WFS.

 

BLG Technology System

A unique system specifically designed for high alkaline environments such as contact with black liquor from the paper and pulp industry. These are only available and engineered precast shapes.
