AbstractThe 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 behavior. The nature of the strain recovery characteristics were observed to be strongly dependent on the water-cement ratio. Aspects of a strain recovery mechanism based on re-adsorption of water on unloading are discussed.
