Monitoring the early-age properties of cement-based concrete by electrical conductance in combination with isothermal calorimetry
Paper i proceeding, 2025
A novel method based on electrical conductance in combination with isothermal calorimetry was used for monitoring the early-age properties of cement-based concrete. Two different mortars, one with OPC and another with 50% GGBS replacement, were tested. Preliminary results show that the proposed method can clearly monitor the hydration process and the structural development in the samples.
