Experimental investigation on fly ash and blast furnace slag in construction of cement concrete pavement

In this paper the effect of using fly ash and blast furnace slag as partial replacement of cement and coarse aggregate respectively in concrete mixes is presented with the help of laboratory investigations. The results of a laboratory experiment carried out on blended concrete, with respect to designed M25 grade of concrete, produced from 14%, 30% and 45% replacement of cement with fly ash, along with a constant 30% replacement of normal coarse aggregate with air cooled blast furnace slag, have been reported. The laboratory program included workability, compressive strength, split-tensile strength, flexural strength and elastic modulus of blended concrete. The results showed that blended concrete incorporating 30% fly ash and 30% blast furnace slag can be used for concrete pavements.
