Abstract

Mechanical behaviour of fibre-reinforced concrete is influenced both by the properties of the fibres (geometry, aspectratio, dosage) and the properties of the matrix (concrete grade, curing time, water-to-cement ratio). Many researchstudies have been published that focus on the influence of different kinds of fibres on the final properties of concrete.Against this the influence of the matrix grade on the mechanical properties of fibre-reinforced concrete is a topic thatis almost unexplored. A mechanical characterisation of fibre-reinforced concrete in the hardened and fresh states iscarried out, varying the concrete grade, the fibre dosage and the fibre type (steel and polyester). The results of theexperimental research indicate the importance of the matrix grade on the bond between the steel fibre and the matrixand, consequently, on the mechanical performances of the composite material. Furthermore the concrete grade also; influences the minimum volume fraction of polyester fibres affecting the matrix toughness.
