EFFECT ON PROPERTIES OF CONCRETE IN PARTIAL REPLACEMENT OF FINE AGGREGATE BY STEEL SLAG AND CEMENT BY METAKAOLIN

摘要

In the present investigation, metakaolin is used to replace a portion of the cement and induction furnace steel slag as partial replacement of fine aggregate in concrete. Metakaolin is a dehydroxylated aluminium silicate pozzolanic material obtained from kaolinite clay mineral. Induction Furnace steel slag is obtained as an industrial by-product during steel production. Hexagonal shaped paver block specimens of side 120 mm and height 80 mm are casted. Compressive strength, flexural Strength, split tensile strength, abrasion, water absorption, acid and alkali attack tests were performed. The results show that optimum level replacement of metakaolin (cement) and IF steel slag (fine aggregate) in concrete is 10% and 20% respectively.
