Abstract |
The aim of the present work is to make a comparative study on M30 grade self-compacting concrete by partial replacement of glass fiber and copper fiber reinforcement with conventional concrete. The variables involved in the study are type and different percentage of fibers. The basic properties of fresh SCC and mechanical properties, compression strength, Split Tensile Strength, Flexural Strength of hardened concrete were studied. The fibers used in the study are 12 mm long glass fiber and copper fiber. The volume fractions of fiber taken are 0%, 1%, 1.5%, 2%, and 2.5%. The project embraced two stages. The first stage consisted of the development of SCC mix design of M30 grade and in the second stage, different fibers like Glass and copper Fibers are added to the SCC mixes and their fresh and hardened properties were determined and compared. The study showed significant enlargements in all properties of self-compacting concrete by adding fibers of different types and volume fractions. CFRSCC exhibited the best performance followed by GFRSCC in hardened state whereas poorest in the fresh state owing to its high water absorption. GFRSCC exhibited the best performance in a fresh state. The present study concludes that in terms of overall performances, optimum dosage and cost of fiber is the best option in improving the overall quality of self-compacting concrete |
