摘要：This paper presents the results of experimental research work done in high strength concrete byreplacing cement with mineral admixtures. The main aim of this work is to determine the creep strain values of a M60grade concrete by replacing cement with flyash , silica fume and ground granulated blast furnace slag (GGBS) by10% . Each mix is tested for compression, flexural, split tensile, modulus of elasticity and creep deformation valuesafter 28 days of casting. The Creep deformation is measured using DEMEC mechanical strain guage with 10 minutestime interval for 1st day and 30 minutes time interval for next 2 days continuously. The creep results available from thisexperimental work involve the specimens under sustained load. A time-dependent creep strain is provided in a graphshowing its variation. From the experimental results it is observed that the creep strain is inversely proportional to thecompression strength of concrete.
