High alumina refractory mortars
Vitset ready mixed high alumina refractory cements and mortars are specially formulated for jointing, coating, and patching in a wide range of high-temperature industrial applications. Designed to perform in temperatures ranging from 1450°C (2640°F) to 1860°C (3380°F), these air-setting mortars offer excellent bonding properties both at ambient temperatures and during service. The recommended mortar bed thickness for jointing firebricks is 3 mm, ensuring optimal mechanical strength and thermal performance.
Vitset 45 - High-Temperature Refractory Mortar
Vitset 45 is an air-setting, ready-to-use refractory mortar suitable for trowelling, patching, and jointing in high-temperature environments up to 1700°C (3100°F). It forms a strong air-dried bond with all grades of refractory bricks and is also compatible with ceramic fibre materials. The easy-to-apply consistency makes it ideal for both new installations and maintenance work.
Examples of Applications: Vitset 45 is widely used in the setting and repair of dense firebricks, high-temperature insulation bricks, and ceramic fibre blankets, boards, and modules. Common industrial uses include:
-
Foundry ladles
-
Foundry furnaces
-
Rotary cement kilns
-
Ceramic kilns and kiln cars

Vitset 80 - High Alumina Refractory Mortar for Steel and Foundry Applications
Vitset 80 is a ready mixed, air-setting refractory mortar suitable for setting all grades of refractory bricks. It can also be supplied in a thinner consistency for brick dipping, coating, and spraying applications. Vitset 80 forms a robust air-set bond that is slightly expansile at 1540°C, ensuring tight joints without shrinkage. It exhibits excellent resistance to slag attack and maintains structural stability at temperatures up to 1750°C.
Examples of Applications: Vitset 80 is widely used in steelworks and foundries, particularly in applications where high temperature and chemical attack resistance are essential. Typical uses include:
-
Setting high alumina bricks in safety linings of pouring ladles
-
Setting bricks and purging nozzles in continuous casting tundishes
-
Rendering or dipping in refractory installations exposed to aggressive slag environments
