MECHANICAL PROPERTIES OF STEEL FIBRE USED CONCRETE PAVING BLOCK

Abstract

Plain concrete is a brittle material. Under impact and dynamic loading plain concrete exhibits extensive cracking and undergoes brittle failure. The concrete is weak in tension and flexure hence to overcome this problem cement concrete, modification in traditional cement concrete has become mandatory. In this modern age, Concrete paving blocks are ideal materials on Open spaces surrounding residential, public, commercial, & industrial buildings. They are used for the footpaths in the city and walk way in the gardens know a day's paving blocks are also used for light and heavy traffic roads due to their easy laying, better look and finish. In this paper, a parametric experimental study for producing paving blocks using steel fibres is presented Fibre reinforced concrete (FRC) is defined as concrete made with hydraulic cement, containing fine and coarse aggregate and discontinuous discrete fibre. In FRC, thousands of small steel fibres are dispersed and distributed randomly in the concrete during mixing, and thus improve concrete properties in all directions. FRC is being increasingly used to increase static strength, energy absorbing qualities and better fatigue strength of paving blocks.
