Method for Assessing the Density of a Concrete Mix during Molding

Introduction. Concrete mix compaction is one of the most pressing topics in modern construction. Vibration compaction is a key method used to ensure uniform distribution of concrete mix components and removal of air voids. The process of manufacturing reinforced concrete products is complex and labor-intensive and requires significant responsibility and attention. The quality of compaction of mixtures affects the physical and mechanical properties of molded products, including strength, water resistance, frost resistance and other important parameters. A correctly compacted mix ensures uniformity of properties of finished products, accuracy of geometric shapes and good quality of its front surface. The aim of this article is to study the existing works of the authors and identify the development area in the method of assessing the density of concrete mixture during molding with the possible development of the device necessary for this. Materials and methods. Concrete mix was chosen as the object of the study. Control of concrete vibration compaction parameters requires careful planning, taking into account the type of mix, the shape of the structure and quality requirements. This section covers the development of a fundamentally new device “Shar-1”. Research results. The results of the development of a device for measuring the density of concrete mixture have been successfully proved experimentally. The device makes it possible to evaluate the compaction of the mixture during the forming process, recording data in real time and allowing further analyses of the concrete mixture compaction process. This helps to improve the quality control of concrete mixtures at the stage of moulding, which is important for improving the reliability and durability of concrete structures. The use of “Shar-1” simplifies and speeds up the testing process, reducing the influence of subjective factors and increasing the objectivity of measurements. Discussion and Conclusion. The section focuses on the difference between traditional research on control of concrete mixture compaction and with the use of the device “Shar-1”, which allows to measure the density of concrete mixture in the process of moulding. The method allows to quickly obtain data on density, timely correct the technology if necessary. It is planned to improve the device with additional functions in the future.
