This article presents the results of research on cement bound materials. The research was conducted for an investment in Poland. Three mixtures differing in grain size distribution and cement content were tested. For this purpose, a research method suitable for concrete was adapted. The result of the analyses was the selection of one of the mixtures, which was used in the implementation of the project. © 2024 The Authors. Published by Elsevier B.V.

1. Introduction 1.1. Background of the conducted research

Elastic modulus (E) is one of the parameters defining elastic behaviour of a material under analysis (Zvonari ć et al., 2024). It represents the resistance of a given material to elongation or contraction in the elastic or Hooke’s law
