Concrete is so far the most widely used construction material today. This project deals about the influence of Fly ash, GGBS (Ground Granulated Blast furnace Slag), Silica Fume, and Metakaoline as partial replacement of cement and Optical Fiber as fine aggregate in normal concrete mix. Fly ash, GGBS (Ground Granulated Blast furnace Slag), silica fume, Metakaoline is used as partial replacement to the cement; Optical Fiber is used as partial replacement to fine aggregates. Mix design is to be prepared for M25 concrete grade and different proportions to which Fly ash, GGBS (Ground Granulated Blast furnace Slag), Optical Fiber, Silica Fume, Metakaoline can be used. For this 3 trail mixes with varying proportions are used. The mix design is to be prepared for M25 concrete grade. The trail mixes are replacement of cement by Fly ash, GGBS, Silica Fume, Metakaoline as 10%, 15%, 20% individually and also replacement of fine aggregate by optical fiber by 2%, 4%, 6% respectively with above cement replacing percentages. For hardened properties of concrete specimens were tested at the age of 7 days and 28days of curing in water. Casting cubes of size 150mm×150mm×150mm, for the determination of compressive strength of concrete. In which mix proportion, the compressive strength gets the maximum, that mix proportion is considered for the casting of beams to find out the flexural strength of that beam.
