STUDY ON HIGH PERFORMANCE CONCRETE BEAM UNDER CYCLIC LOADING CONDITIONS BY PARTIAL REPLACEMENT OF FLY ASH AND QUARRY DUST

This research paper describes the study on high performance concrete while partially replace the fly ash and quarry dust as a cement and fine aggregate. These are replaced at the percentages of 0%, 10%, 20%, 30%, 40% and 50%. The high performance concrete has been designed at M60 grade concrete. Especially this study observes the behavior and performance of concrete, when the cements and fine aggregate replaced partially. The conplast SP430 super plasticizer was used in concrete. This super plasticizer reacts as a water reducing agent in high performance concrete. This is adding 0.5% in concrete. The steel fibers also additionally added into the concrete while casting. Fibers are added into the fly ash concrete at 0.75% and 1%. The aspect ratio of the steel fiber was 50% and the size of the fiber was 0.6mm and 0.7mm. in this study 0.6mm diameter of steel fibers were used. Finally this study shows the strength, deflection, residual strength and stiffness degradation of the high performance fly ash and quarry dust concrete under cyclic loading conditions.
