The experimental investigation deals with the study of combined effect of GGBS and Metakaolin in M40 grade of concrete reinforced with polypropylene fibres. The cement is replaced up to 40% by GGBS and metakaolin. The addition of polypropylene fibres is fixed as 1% of volume of concrete. The aim of the experimental program is to find the optimum dosage of GGBS and Metakaolin. To achieve so various tests are performed which includes Compression, split tensile and flexural tests at 3,7,28 days of curing of the sample specimens. The aim further extends to know the durability property of the fibre reinforced concrete produced by partially replacing cement by GGBS and Metakaolin. The results revealed that the mix M20G20 i.e., cement replaced with Metakaolin 20% and GGBS 20% showed better results than any mix. The quantum of increase in compressive strength for this optimum mix was 7.15% when compared to conventional concrete. Also the mix M20G20 was found to have greater resistance against acid than the conventional mix.
