A study of transitional thermal creep in hardened cement paste

Abstract

Synopsis Creep measurements on hardened cement paste subject to various temperaturehistories are described. It wasfound that, when loaded prisms were gradually heated from 2O° to 60°C, creep increased substantially. This transitional thermal creep was pronounced for virgin heating, but was also present to a lesser extent during a second heating to 60°C. Delays in loading and heating generally led to smaller creep strains, and cooling did not induce any transitional thermal creep.
