An attempt to identify concrete strength parameters by simulating standardized tests

This study focuses on transport infrastructure, particularly the construction and maintenance of concrete airport pavements, which are crucial for aviation transport safety. The main objective of the research was to evaluate the effectiveness of standard methods for determining the strength of concrete used in airport slabs (LWS) and road slabs (MON). The study employed the finite element method (FEM), comparing its results with experimental data. Simulations of concrete compression and bending tests were conducted in accordance with procedures described in standardization documents. The research results confirmed the usefulness of standard methods for testing and determining concrete strength. At the same time, the study highlighted the limitations of simplified calculation formulas contained in the standards. This research was carried out with the support of the Interdisciplinary Centre for Mathematical and Computational Modelling at the University of Warsaw (ICM UW).
