Ductile and brittle effects of fibre reinforcements in low calcium cementitious matrix

Abstract

The motivation of the present investigation has analyzed the engineering properties of discrete fibre addition in conventional concrete. A comparative evaluation was studied systematically in the performance of concrete with the addition of two different fibres such as polypropylene (pp) and steel fibres. The laboratory test results lead the conclusions that the brittle matrix provided a maximum strength up to 45.30 MPa was noticed at 28 days moist curing by the inclusion of steel fibres (1% Vf). However, in the case of maximum strength up to 42.50 MPa was noticed when the addition of polypropylene fibres (0.1% Vf) at 28 days moist curing. It can be subsequently proved either high strength (steel) or high deformability fibres (pp) improve the composite matrix when the addition of discrete fibres in conventional concrete.
