Abstract
Abstract: Pozzolanic materials such as ground granulated blast furnace slag i.e. GGBS, Solid waste ash, iron husk, silica fumes, iron slag etc are the most common industrial by-products generated. Some of these waste material shows similar properties/elements as that of cement. So these waste materials can be used in concrete as a partial replacement of cement. So, in this study, the attempt to partially replace the cement by GGBS and solid waste ash is carried out. Here, the cement is partially replaced by different percentage of GGBS (10%, 15%, 20% and 25%) and same for solid waste ash (4%, 6%, 8% and 10%) and the concrete mixes were made along with the control mix concrete. Workability test, compressive strength test etc. are performed on the specimen. From the results, it is observed that the workability of the concrete gets affected due to replacement by GGBS and solid waste ash. The compressive strength of GGBS concrete increases till 20% replacement whereas the compressive strength of solid waste ash concrete increase till 4% replacement. Further that it shows decrease in value. It is concluded that the optimum percentage for partial replacement of cement for GGBS is 20% and for solid waste ash is 4%.
