Mechanical strength of fibrous concrete with waste rural materials

Abstract

This study presents reusing of locally available waste fibrous materials as concrete composites. Mechanical strength properties (compressive strength, split tensile strength, modulus of elasticity, modulus of rupture and shear strength) of synthetic fibres (nylon, plastic and tyre) with volume fractions (0.5%, 1% and 1.5%) and aspect ratios (30, 60 and 90) were evaluated. Empirical relation was proposed for mechanical strength in relation with fibre reinforcing index (FRI) and compared with experimental results. Concrete mixed with rural waste fibres improved mechanical strength.
