Abstract

An experimental investigation was carried out to study the effect of inclusion of metakaolin and steel fibers on high strength concrete in flexure and split tensile strength. The beams of 150x150x700 mm were casted. M60 grade of concrete was used. Superplasticizers were used to improve workability. The metakolin was added upto 20% with the increments of 5% and steel fibers were added upto 5% with the increment of 0.5%. Various specimens were casted and tested for flexure at the age of 7 and 28 days. Split tensile test was conducted on 1/3rd prism yielded from the flexure test. Mathematical modeling was done by regression analysis. Four pointloading was applied on beam for flexure test on 400KN universal testing machine. Compression testing machine of 2000KN was exploited for split tensile test. Area under load deflection was found out to define toughness of fiber reinforced concrete.
