Thermal Ceramics’ refractory mortars are normally supplied as ready-to-use wet blends of finely-ground aggregates and special binders. They develop good strength on air drying, forming strong joints and conferring an almost monolithic structure to the brickwork.
Maximum continuous use temperature
The maximum continuous use temperature depends on the application. In case of doubt, refer to your local Thermal Ceramics distributor for advice.
JM 2600: This is an air-setting cement developed for use in lowertemperature applications, where a high-strength bond is required. It is recommended for mortaring insulating firebricks for operating temperatures up to 1430°C and can be used for both trowelled and dipped joints.
Blakite: This is a highly refractory mortar, dark grey in colour, which has a high water-retention characteristic. It was specially developed for laying insulating firebricks but is also suitable for use with super-duty and high alumina dense refractory bricks, at operating temperatures up to 1650°C. It is supplied in a consistency suitable for shallow patching or trowelling but requires the addition of approximately 5% water for dipping. Blakite is a good choice as a single, general-purpose mortar on projects involving mainly insulating firebricks but also including some dense firebricks.
Blakite V: This is the standard product with a harder consistency to be used to glue special refractory shapes and steel plates.
JM 3300: A very highly refractory air-setting mortar suitable for laying JM 32 insulating firebricks, and high alumina dense refractory bricks and for operating temperatures up to 1760°C.
