Evaluation of Shotcrete Quality Using Different Methods

In this paper, a presentation is given of destructive and non-destructive test methods for evaluating the shotcrete strength and quality of a tunnel primary lining. The research was conducted in the tunnels that are under construction on the Zagreb - Rijeka highway in Croatia. Testing was carried out on site and in a laboratory on specimens taken from the tunnels. The non-destructive methods included an ultrasonic pulse velocity method and a hammer test. The results of this research work show the relation between shotcrete properties (compressive strength, modulus of elasticity, and homogeneity) measured across the tunnel profile and along the whole tunnel by applying the destructive and non-destructive methods. The main purpose of this experiment is the development of a method that evaluates the quality of shotcrete in underground structures during and after the construction work. Through the application of non-destructive and destructive test methods it is possible to assess the state of a tunnel in order to improve construction work. This will result in the higher quality of the tunnel lining and durability of the tunnel as a whole and cut remediation and maintenance costs.
