Original Abstract

This paper presents the values of basic mechanical-fracture parameters of concrete specimens (strength class C30/37): compressive strength, splitting tensile strength, modulus of elasticity, effective fracture toughness and specific fracture energy. Three-point bending tests of specimens (100x100x400 mm) with the central edge notch were performed to determine mentioned fracture characteristics of material. Fragments of specimens obtained after performing three-point bending tests were used to determine the values of splitting tensile strength and compressive strength. The cubes with length of the edge 150 mm were also used to determine the values of compressive strength. The age of specimens was 28, 98 and 159 days. The values of mentioned parameters obtained from the static fracture tests will be used as a correct starting point to evaluate fatigue parameters of concrete.
