An inorganic product consisting of molten mass of Sulphur and inert filler. In addition, presence of special plasticizer imparts superior thermal resistance qualities. Sulphur mortars have good resistance to most of the acids except strong oxidizing acids, but have poor resistance to most alkalis.
Sulphur mortars are used for jointing of Acid proof bricks and tiles in floors, lining of storage tanks, pickling tanks, sumps, drains etc. Special care should be taken so that Sulphur is not overheated during melting process.
