Refractory mastics are manufactured on the base of calcinated fireclay, andalusite, bauxite, high-alumina aggregates, alumina, aluminium oxides, refractory clays and kaolins, plastifying agents and other additives on the advanced technological lines.
They are prepared for dispatching as dry mixes in paper or big bags, or ready to use plastic mixes in buckets. The products are intended for fireclay and high-alumina linings as jointing material and bricklaying material. Owing to their excellent workability and grain size in particular, they are advisable for linings where tight up joints are demanded.
