Acceleration in the cost of repair and analysis of concrete structure which enlarge distress much in advance than the design service life has twisted the meeting point on the durability aspect of concrete. headed for decide the chemical conflict of sisal fibre in Portland cement concrete elements. An investigational study result conducted to evaluate the durability character of plain and fibre reinforced special concrete and its association with Portland cement based humdrum concrete is accessible in this paper. The durability test measured in this study includes water absorption, saturated water absorption (SWA),impact load, rapid chloride penetrability test(RCPT). The experimental Test results discovered that plain and fibre reinforced special concrete possesses higher durability character than conformist concrete of the similar grade with respect to most of the durability tests.
