Splet01. jan. 2013 · Non-destructive tests of shotcrete For non-destructive test of shotcrete, rebound method was used (Schmidt rebound hammer type N) and ultrasonic pulse method. Measurements were carried out on concrete blocks with dimensions 500 x 300 x 150 mm and on core drills at the age of concrete 3, 7, 14 and 28 days. SpletMy master's thesis topic is "Laboratory testing of shotcrete with fibres of steel, basalt or synthetic materials". The aim of the thesis is to study the mechanical behaviour and property of the different fibres in shotcrete by testing the shotcrete samples in two different methods, i.e., beam testing and round panel determinate testing. predictions of baba vanga 2020
