Introduction. Ferrous sulfate is a solid industrial byproduct of titanium dioxide manufacture by the sulfate method and its main mineral component is FeSO 4 7H 2 O. In China, 98% of the titanium dioxide is manufactured using the sulfuric acid method, thereby producing over 7 million tons of ferrous sulfate waste each year, and the annual IS 262 (1982): Specification for Portland cement for use in prestressed concrete. This standard covers the requirements and methods of testing for ordinary and rapid-hardening Portland cement suitable for use in prestressed concrete structures. It also provides guidance on storage, handling and admixtures of cement. This standard is IS 262 (1982): Ferrous Sulphate, Heptahydrate
