The effect of electromagnetic treatment of concentrated cement slurry on the physical and mechanical properties

Abstract

Problem statement.At the beginning of the week, in Ukraine the transfer is more significant in concrete consolidation. Especially important is the need to lower the supply of concrete and concrete, with the change in portability, without any loss of strength. The purpose of the article. For increased concrete and concrete strength, when changing the number of Portland cement, it is necessary to consolidate the various methods of the concrete concrete process. The most common are methods of heat exposure, as well as the use of various chemical additives. Electrophysical methods of influence are used to a lesser extent, namely intensification with the help of electric and electromagnetic fields. Purpose.To improve the quality and strength of concrete, while reducing the use of Portland cement, it is necessary to use various methods to intensify the concrete preparation process. Methodology. From the electrophysical methods of intensifying concrete preparation processes, the method of electromagnetic treatment of concentrated cement slurry, which was passed through an alternating electromagnetic field and was used to prepare the concrete mixture, is promising. Results. The performed tests showed that when an electromagnetic field is infused, a positive effect is induced to concentrate on a concentrated cement suspension in the process of structural adjustment and reduction of physical and mechanical power to concrete. It has been established that, as a result of processing, there is a greater variety, dispersion and better storage of cement and a form of cemented stone structure. Conclusion. Outlined above allows us to assert that electromagnetic processing of cement paste has a positive effect in the process of structure formation and the improvement of physico-mechanical properties of concrete based on the processed in the electromagnetic field of the cement paste.
