ABSTRACT

The paper presents results of the calculation of the ASTM C1018 toughness index of fibre reinforced concrete materials with two types of matrix /limestone and basalt aggregates/, two kinds of fibre /plain round fibres and Harex fibres/ and three fibre volume contents /0.7%, 1*3%, 1.45%/• The results are taken from three different tests which were carried out with one year pause between each of them. The values of tough­ ness indices 1^ are compared with the values of dynamic and static Young’s modulus, compressive strength, flexural strength, type of matrix, kind of fibre and fibre content.
