• Description: Due to its exceptional range of properties and low cost polypropylene (PP) fibres are nowadays widely used in modern industry. Among the interesting application belongs the fibre-reinforcement of concrete which is used to improve the mechanical properties as toughness, tensile strength and flexural ductility of concrete. Unfortunately the surface adhesion of PP fibres in cementitious matrix is generally problematic due to its low hydrophobicity of PP surface. In this paper we present the possibility of improving the wettability of reinforcing PP fibres in atmospheric pressure plasma.
