The strength of cement stone has a significant impact on the properties of concrete. Therefore, much attention is paid to the formation of the structure and properties of cement stone. Improvement of the properties is achieved by activating the hardening of the cement paste in various ways. One of such methods is the processing of cement paste in electromagnetic field mixing with water or cement suspension of low concentration. When processing concentrated cement suspension in an alternating electromagnetic field, there is the intensification of dissolution, dispergation, hydration of the cement components and the formation of a cohesively dispersed structure of cement stone. The given paper gives research results of the impact of the processing concentrated cement suspension containing lime in an alternating electromagnetic field on hardening and strength processes of cement stone. The purpose of the article is to study the joint influence of alternating electromagnetic field and Са(ОН)2 on the properties of cement stone. Conclusion. The impact of the alternating electromagnetic field on the concentrated cement suspension, containing Са(ОН)2 as the result of synergetic effect enables to intensify hardening process and increasing the physical and mechanical properties of cement stone.
