摘要: The dynamic elastic modulus and damping coefficient of hardened cement paste is measured by exciting the natural mode oscillation a beam in temperature range between +20 −160°C. from system water vapour exchange with specimen are negligible. A new statistical model proposed for combining moduli constituents: solid matrix, ice air. Water-saturated specimens were measured, delivering results solid, applying model.
