Determination of Structural Changes in Water and in Aqueous Solutions under External Influences | Chapter 03 | Innovations in Science and Technology Vol. 2

 The proposes a novel approach to the development of cement compositions based on technologies that meet technological accessibility and efficiency, environmental safety, sustainability, biocompatibility, economics, energy efficiency, and resource conservation requirements. This innovative method is based on evaluating electrical characteristics in the frequency range of 1 kHz to 3000 kHz using various measuring cells to examine changes in the structure of water or aqueous electrolyte solutions under diverse influences. There were three different types of measurement cells employed. In the first case, the measuring cell had a different height of liquid layer between the capacitor plates; in the second case, a rectangular measuring cell with a distance between the capacitor plates of 7 cm was used; and in the third case, the measuring cell was a test tube with a diameter of 20 mm and a length of 200 mm, in which the capacitor plates are located relative to each other in parallel planes and do not have surfaces located opposite each other. Based on the findings, it was discovered that a change in the structure of water is the fundamental mechanism of action of a magnetic field, temperature, chemical additives, ultraviolet irradiation, or a combination of these factors on water and water-containing systems. New approaches for enhancing the strength of cement compositions were developed using the defined criteria for examining the structure of water and water-containing systems. The addition of various compounds and/or field effects on cement systems resulted in a considerable increase in the strength of hardened cement paste and concretes, according to the findings. This allowed the cement-sand mortar's compressive strength to be increased by 30-45 percent.
