Experimental methods of determination of brittleness and toughness of fibre concretes are considered. The results of flexural toughness tests are presented and discussed. The range of investigation included ordinary concrete, both cast and sprayed, as well as cement mortars modified with mineral additives. The influence of dispersed reinforcement, i.e. steel fibres, carbon fibres and glass fibres, on flexural toughness parameters is analysed. Effects of pozzolanic additives on the flexural toughness of fibre cement composites are also presented. The criteria for the selection of fibres and their volume fractions are discussed. The suitability of test methods for determination of material parameters of fibre concrete composites is evaluated.

W pracy omówiono metody określania kruchości i odporności na pękanie fibrobetonów. Zakres badań obejmował betony kruszywowe oraz natryskiwane, a także drobnoziarniste zaprawy cementowe modyfikowane dodatkami mineralnymi. Przeanalizowano wpływ zbrojenia rozproszonego w postaci włókien węglowych i szklanych na parametry odporności na pękanie przy zginaniu. Oceniono adekwatność metod badawczych do określania właściwości materiałowych kompozytów fibrobetonowych.
