Abstract

A high performance fibre concrete with a cylinder strength of about 80 MPa was developed and tested both under laboratory and site conditions. The post-cracking properties were determined in a series of three-point notched beam tests according to EN 14651. Subsequently, double punch tests on 150 mm cubes were carried out to verify whether such tests could be used for control of the properties of the concrete cast at site. It was shown that the same relations can be obtained by using simple conversion factors. Additionally, it was studied if it is possible to test round panels according to ASTM C1550-02 to verify the properties of the fibre concrete. Also here, it turned out that it is possible to derive simple conversion factors to relate the results of the round panel tests to those of the notched beam tests. The findings provide useful information for a practical quality assessment with regard to the execution of fibre reinforced concrete structures.
