Abstract:
Construction of modern structures and reconstruction of the existing onesimpose very demanding requirements for the quality of used materials. Highperformance hybrid fibre reinforced concrete appears to be a material of great importance in the future. An innovative type of this concrete was tested and its properties were compared with those of reactive powder concrete, high performanceconcrete and plain concrete. Compressive strength, flexural strength, toughness and modulus of elasticity were measured. For the purposes of toughness testing, an acousticemission technique was used to detect cracking and fracture properties.
