Early age shrinkage pattern of concrete on replacement of fine aggregate with industrial by-product

Publication date: Available online 1 June 2016 Source:Journal of Radiation Research and Applied Sciences Author(s): R.K. Mishra, R.K. Tripathi, Vikas Dubey This is an experimental work carried out to investigate early age shrinkage pattern of concrete, prepared, on 50% replacement of industrial by-product (like pond ash and granulated blast furnace slag) as fine aggregate using OPC, PPC and PSC as a binder. This is to observe the effect of pond ash and slag as they are having some cementitious properties and effect of cement type is also discussed. All the mixes were prepared keeping in view of pumpable concrete without any super plasticizers. Higher shrinkage value indicates the presence of more bleed water or internal moisture. It is concluded that slag is the best option for fine aggregate replacement for concrete making and durable structure.
