摘要：

The total strain and strain recovery-time response of hardened cement paste subjected to a sustained load was followed using impedance spectroscopy. An immediate increase in the high-frequency arc diameter on removal of the load was interpreted in terms of microstructural behaviour The nature of the strain recovery characteristics was observed to be strongly dependent on the water/cement ratio. Aspects of a strain recovery mechanism based on readsorption of water on unloading are discussed.
