The investigation of early hydration and pore structure for limestone powder wastes blended cement pastes
Journal article, 2019

This work systematically investigates the early hydration process and pore structure evolution of high limestone powder wastes content blended cement pastes by non-contact impedance measurement and microstructural tests. According to the evolution of impedance response, the early hydration process of blende cement pastes can be divided into four stages, denominated as dissolution, acceleration, dynamic balance and hardened stages, respectively. Dynamic balance stage not present in hydration process of pure cement, is a characteristic hydration stage for blended cement pastes. Furthermore, fractal approach for predicting the evolution of pore structure is proposed originally, based on the impedance results.
