Structural and Temperature Effects on Electrical Resistivity of Concrete During Its Hardening and Strengthening

摘要：

　　The presented work describes the research findings related to the impact of temperature and structural effects on electrical resistivity of concrete during its hardening.The methodology is based on formulation and implementation of the concept of concrete iso-strength(iso-structural)condition.The experimental data analysis under the iso-strength conditions within the temperature range: 283–313 0K allows to suggest that the state of electrically conductive phase-structured water consecutively transforms from liquid to quasi-solid.The ability is shown of separating the temperature and structural effects and their impact on the value and the nature of electrical resistivity in the process of concrete hardening.The temperature impact on the resistivity changes in the hardening process.Upon reaching a certain strength value,corresponding to a sufficiently high level of structure development,the temperature coefficient of electrical resistivity changes its sign: it changes from a negative to a positive area.
