Refractory mortar

Silico-aluminous refractory mortars are mixtures of refractory ceramic materials, designed for laying and bonding refractory bricks, filling joints and improving the strength and gas-tightness of masonry. They are mixed with water and applied in thin layers of 1–3 mm, with full hardening occurring under the effect of high temperatures. They are intended exclusively for refractory masonry, are not to be used as plaster or adhesive, and have an unlimited shelf life.
