Electrodeless cement concrete resistivity tester

GCCR-5Electrodeless cement concrete resistivity tester

Product Introduction Products

Electrodeless cement concrete resistivity testerIt is a new instrument developed by the Hong Kong University of Science and Technology for the research and quality control of cement and concrete foundations. This instrument uses the principle of a transformer to measure the electrical resistivity of cement-based materials during hydration and solidification processes in a non-contact manner, solving the contact problem of traditional electrode measurement methods. It is an instrument that can accurately measure the changes in electrical resistivity of freshly mixed cement-based materials during hydration processes.

The electrical resistivity of freshly mixed cement-based materials directly reflects the changes in their internal microstructure and ion concentration over time, and is expected to be closely related to the hydration and solidification processes. By monitoring the changes in electrical resistivity of cement-based materials over time from pouring to solidification, the physical and mechanical properties and development trends of cement-based materials can be inferred, providing a new and accurate means for the research of cement-based materials and quality control of cement concrete.

Product Highlights

GCCR-5 is a new generation product following GCCR-1, R-2, and R-3. GCCR-5 has significantly improved in terms of ease of use, operational stability, and testing accuracy compared to previous generations of products. GCCR-5 can monitor and analyze samples covering all cementitious materials, liquid materials, and freshly mixed cement-based materials. It is particularly suitable for users to automatically track the phase transition, solidification hardening, hydration, and other processes of materials in real-time throughout the entire process. Compared with traditional resistivity measurement methods and equipment, GCCR-5 does not use contact electrodes to measure the resistivity of cement-based materials, avoiding the impact of drying shrinkage, cracking, and polarization of cement-based materials on contact electrodes during testing. GCCR-5 has high accuracy and adaptability in resistivity measurement. At present, instruments that can accurately measure the changes in electrical resistivity of freshly mixed cement-based materials during the hydration process.
