Title of the articleModeling of concrete mixture plastic properties
Abstract.Problem statement. The purpose of the study is to develop a mathematical model of the plasticity of a fine-grained concrete mixture, which allows calculating the ultimate tensile strength of the mixture of known composition. Results. The main results of the study are obtaining a mathematical model of the plasticity of the concrete mixture, which establishes the dependence of the ultimate tensile strength on the main factors and demonstrates good statistical indicators, namely: the correlation coefficient is 0,997; the average approximation error is 5,7 %. Conclusions. The significance of the results for the construction industry consists in obtaining a mathematical model that allows calculating the ultimate tensile strength of a concrete mixture of known composition without resorting to testing, which can be used in designing the composition of a concrete mixture in order to ensure given plasticity.
Keywords.concrete mixture, continuous formwork-free shaping, rheology, plasticity, ultimate tensile strength.
