Investigation of the early-age microstructural development of hydrating cement pastes through electrical resistivity measurements

Case Studies in Construction Materials, 2020
The non-contact electrical resistivity method was employed to investigate the microstructural development of three grades of cement under a fixed water-to-cement ratio (w/c) and the same curing conditions. The method was verified by measuring the heat of

Effect of Chloride on Electrical Resistivity in Carbonated and Non-Carbonated Concrete

Applied Sciences, 2020
The resistivity of a concrete structure exposed to chloride ions indicates the risk of early corrosion damage, because a low resistivity is related to rapid chloride penetration and to a high corrosion rate. Concrete resistivity is a geometry-independent
