| Title of the article | Selection of the component composition of gypsum-cement-pozzolanic binder, providing the best strength and water resistance |
| Abstract. | Problem statement. The multicomponent nature of gypsum-cement-pozzolanic binder and concrete based on it predetermines the polyrecipe which is dictated by the quality of all components. A rational approach to solving this problem is a planned experiment, which allows obtaining a reliable and fast result with minimal costs. This is achieved by the correct choice of the experimental plan. Therefore, the purpose of this work is to establish independent factors influencing the behavior of responses and creating a dependency model. To achieve this goal, the following tasks were solved: establishing a set of gypsum-cement-pozzolanic binder components influencing the behavior of the most important characteristics of the hardened matrix, namely, the amount of cement, active mineral and chemical additives; determining the mathematical plan of the experiment; establishing independent factors influencing the behavior of responses and creating mathematical models of the dependencies of compressive strength, softening coefficient and water resistance on the composition of gypsum-cement-pozzolanic binder. Results. The paper presents the results of a study of the physical and physical-mechanical properties of gypsum-cement-pozzolan binder, depending on its component composition. Using mathematical models constructed after mathematical processing of the results of the planned experiment, the task of selecting the component composition of gypsum-cement-pozzolan binder was solved, for which the compressive strength after 28 days and the softening coefficient would be the highest, and the water absorption would not exceed 9%. Conclusions. The significance of the obtained results for the construction industry lies in the optimization of the gypsum-cement-pozzolanic composition formulation and the selection of effective modifying additives, which will expand the areas of application of these materials and increase their competitiveness in the construction market. |
