STATISTICAL ASPECTS OF STRENGTH AND FRACTURE BEHAVIOUR OF CONCRETE

In the present paper, a very brief review of various contributions which corroborated the existence of microcracks in concrete and their influence on the mechanical behaviour, is carried out. Based on the existence in concrete of the so-called size effect and the theory of composite materials, a theory is advanced to explain the size effect on the behaviour of concrete. The prediction of the theory e.g., the lower strength, lesser ductility and lesser stiffness associated with specimens of larger sizes, is verified by an experimental investigation in which fibre reinforced mortar briquettes of different sizes are tested in tension. The agreement between the theoretical predictions and experimental observations is very good. However, for a more quantitative evaluation of the theory, further information from experiments is required and this aspect is briefly discussed. See also IRRD Abstract No. 205029
