The Determination of Compressive Strength of Masonry Elements of Monuments by The NDT Methods

Popis výsledku v původním jazyce

Nowadays, the compressive strength of masonry elements is usually determined non-destructively using a rebound hammer Schmidt LB. However, the production of Schmid LB is going to be discontinued soon. The determination of the compressive strength of the masonry elements will become very challenging discipline. Therefore, this work aims to improve the way of assessing the compressive strength of masonry elements with minimal damage to the historic structures. In this paper, the application of alternative methods of determining the compressive strength of masonry elements are verified. This strength is determined by two ways. The rebound hammer Silver Schmidt in versions L, N and L with mushroom plunger, which is designed for control of strength of concrete for formwork removal, were used. The second way is the modified drill, which TZÚS Prague presented in 2020 in a new modifi-cation KV-3. The regression (calibration) curves are deduced for both methods in this paper. The regression (cali-bration) curves were determined on a large set of historic solid fired bricks so that the full spectrum of strengths was represented. The masonry elements were firstly tested non-destructively and then the elements were subjected to destructive measurements.
