Abstract

High performance fibre reinforced shotcrete (HPFRS) is a concrete type differing from other shotcrete types in its higher strengths and in at least one other improved property. In this paper a description is given of the use of HPFRS for the construction of a test section for the primary support of the St. Kuzam Tunnel under construction in Croatia. The test section had a total length of 24 m and was the first application of HPFRS in Croatia. Also, the results of preliminary tests on HPFRS are presented. The test results obtained from the constructed test section illustrate that HPFRS exhibits better properties than conventional fibre reinforced shotcrete which is normally used for the construction of tunnel primary support. In control testing of HPFRS, non-destructive test methods were also employed, with special attention being brought to the importance of their use in tunnelling.
