Jl.JI. • .,,., used for strength evaluation and mathematical expressions are taking into consideration size effects. Published test examined and compared with the proposed formulae. It has been "'"n.,xrn that in the considered cases three possible types of fracture quasi-brittle, pseudo-plastic and an intermediate type. brittleness degree is determined by the values of the ratio characteristic size and concrete characteristic size.
