Abstract
High Performance Concrete (HPC) is a concrete which possess most desirable properties during fresh as well as hardened stage. The ingredients which are used for this, contribute most optimally and efficiently to the various properties like compressive strength, split tensile strength, flexural strength as well as durability. Appropriate use of supplementary cementitious materials and super plasticiser gives good results. Usually GGBFS and micro silica which are the industrial by-products are used as supplementary cementitious materials to produce HPC. In this paper, study of effect of steel fibres, GGBFS and micro silica on the mechanical properties of HPC M80 grade was performed. Hooked end steel fibre was used. The dosage of fibre was 1%. Water binder ratio was 0.26. Mix was designed as per Indian Standards IS 10262. The mix proportion obtained was 1:1.25:2.3 and the dosage of super plasticiser was 1% . The compressive strength obtained was 10.5% greater than the target strength.
