Electrophysical Effect on Concrete Mixtures and Their Components
In this chapter, the mechanism of interaction between the magnetic field and mixing water and its influence on concrete strength is studied. The changes in such parameters as surface tension, dielectric constant, temperature, redox potential, hydrogen ion content, and density in the process of water activation are found in dependence on the strength of the electric current, the activation time, and the degree of water mineralization. A tendency is established to harden the contact layers of concrete aggregates on electric pulse crushing during hardening, regardless of their mineralogical composition. The processing of cement for the preparation of concretes and mortars is considered using mortar mixtures of cement, activated by high-voltage corona discharge. Moreover, the processing of cement dough in concrete is studied and the mechanism of the influence of the electric field on the hardening of cements is explained in addition to the effects at the molecular and ionic levels. Finally, the ultrasonic and acoustic activation of concrete mixtures is reviewed and estimated.
