Comparison of Properties of Shotcrete Tested Using Destructive and Non-destructive Methods

摘要

The paper focuses on possibilities of preparation and observation of basic physical parameters of shotcrete prepared in ordinary laboratory mixer, compacted by vibration combined with defined pressure. The aim is assessment of basic properties of shotcrete: compressive strength of young shotcrete, test core strengths and comparison of results with the results of non-destructive tests of compressive strength. At the same time, homogeneity and consistency of shotcrete will be assessed.
