Structural Behaviour of Concrete with Fly-Ash and Ferrochrome Ash as Partial Replacement of Cement

Abstract

A large quantity of waste materials such as fly ash, silica fume, rice ash husk, and ferrochrome ash etc. are produced as a result of rapid industrialization. Ferrochrome ash is derived from the ferro-alloy industry and fly-ash is developed in thermal power plants as substitute products that can be used as a mineral admixtureinconcrete. The present study considers concrete's structural behavior using different percentage of fly ash and ferrochrome ash as a partial replacement of cement. Experiments were performed tosubstitute cement with 10% fly ash, 20%, 30% and 3% ferrochrome ash. Beam specimens are prepared by following standard procedures. It can be inferred from the study that the sample with 30% fly ash and 3% ferrochrome ash as partial replacement of cement gives maximum load carrying capacity among all the beam specimens. Further, it is observed that the beam specimen with fly ash and ferrochrome ash gives more ductility than of conventional concrete. Hence 30% fly ash and 3% ferrochrome ash as partial replacement of cement has been strongly recommended.
