Abstract :
In this Investigation the strength studies of fibre reinforced self-compacting concrete was studied and the characteristics are compared. The mix proportion is obtained as per the guidelines given by European Federation of producers and contractors of specialists’ products for structure (EFNARC). Self-compacting concrete (SCC) mixes are produced by replacing the cement with 30%, 40% and 50% of ground granulated blast furnace slag, fly ash and with addition of polypropylene synthetic fibre of 0.05% and 0.10% to the SCC concrete. The water-powder (w/p) ratio used in this investigation is 0.4. Super plasticizer used in this study is Glenium B233 and its dosage is 2% to obtain the required SCC mix. Fresh concrete Specimens such as cubes, cylinders and prisms were casted and tested for various mix proportions to study the mechanical properties such as compressive strength, split tensile strength and flexural strength at different ages of concrete such as 7 days, 14 days and 28 days.
