CONCRETE STRUCTURE AND PRODUCTION THEREOF

CONCRETE STRUCTURE AND PRODUCTION THEREOF

PURPOSE:To improve the water-proofing property, compressive strength, etc., of a concrete structure, by mixing a cement with an admixture consisting of a red mud which is a residue generated in the production of alumina from bauxite. CONSTITUTION:Red mud which is a residue generated in the productio...
