Refractory Mortars
High-alumina bonding mortars
Heat-setting and air-setting mortars for bonding fireclay, high-alumina and basic bricks in linings across the steel and cement industries.
Built for consistent service.
Available as wet ready-mixed mortars or dry powders. Each grade is matched to the brickwork it bonds, ensuring compatible thermal expansion and refractoriness. Manufactured with controlled grain sizing to give a workable trowel consistency and tight joint thickness.
