Classification of Electrophysical Methods Regulating the Properties of Cement Concretes
This chapter presents the classification of electrophysical methods, regulating the properties of cement concretes. Then existing methods of electrophysical (in particular, electrothermal) impact in cement concrete technology are discussed. The electromagnetic activation of mixing water being one of the directions in the field of improving the technology for preparing concrete mixtures is considered and experimental results are presented. The electrophysical impact on concrete aggregates is treated, too. In this case, the surface is activated by a pulsed discharge, and the specific granulometric composition of the aggregate is provided. The electrophysical effect on cement slurries and concrete mixtures is studied with classification of corresponding processes and phenomena. By this, the polarization and electrization of concrete mixtures in an external high-voltage electric field in the process of vibration compaction change their rheological properties and create an activated nonequilibrium state of the system improving physical and mechanical properties of the final concrete structure.
