Abstract : Although the abilities of mineral admixtures (silica fume, metakaolin, slag and fly ash) as binary blends to improve the strength of High Performance Concrete (HPC) is well noted in the concrete science, the use of quaternary blends has not found sufficient applications in the production of HPC. This paper focusses on the investigation carried out to assess the strength properties of HPC with quaternary blends. Eleven HPC mixes (5 quaternary + 5 binary + 1 control) were developed with combinations of three mineral admixtures like metakaolin, blast furnace slag and fly ash in different compositions up to 60% cement replacement. In this study, the specimens were cast, cured and tested at 7, 28 and 56 days ages. The quaternary blended mixes containing 5% Metakaolin, 40% blast furnace slag and 10% fly ash performed the best amongst all the mixes. Based on the experimental strengths at 28 days, the compressive strengths at 56 days age are predicted using empirical relations ACI-209, SRPS U.M 1.048 and EN12390, which show a better match with the experimental results
