COMPRESSIVE PROPERTY OF STEEL FIBRE CONCRETE FOR M35 GRADE
Keywords:
common, concrete, compressiveAbstract
In the present work we fabricated and tested Steel fibre mixed concrete sample for compressive property. Here steel fibre is common additive that can improve concrete performance. The aim of this experiment is to measure compressive strengths of concrete of M35 grade with different steel fibre percentages. Concrete specimens with fibre contents of 1, 2 and 3 % by weight were tested. Twenty four cubes were casted for concrete mixes prepared and cured at two different levels of 7 days and 28 days later, it increase its compressive strength. Prepared samples were tested for Compressive Strength testing machine having 2000 KN rated capacity used to measure the compressive strength of each cube. The maximum average compressive strength was 46.25 N/mm2 at 28 days, obtained for a mix of fibre length of 50mm and fibre content of 3.0% by weight and the increase in strength over plain concrete was found to be 7%.The result of this study confirmed that the addition of steel fibre has improved the compressive strength of concrete.
