Abstract
Concrete is a brittle material. The present trend in concrete technology is toward increasing its strength and various properties like durability etc. to meet the demand of modern construction. The aim of this study is to see the effects of two different types of steel fibers in the concrete. In the present work, the Metakaolin were added in the percentage of 5, 10, 15 and 20 along with two different types of steel fibers in the percentage of 0.5, 1 and 1.5 to develop high performance fiber reinforced concrete. Result shows that there is minor increase in the compressive strength but major increase in flexural strength and split tensile strength after 28 days and 56 days of curing. It was also found that with increase in the fiber percentage, resistance towards acid attack and sulphate attack also increases.
