    Abstract

    This paper delineates the effects of temperature and relative humidity on static strength (fatigue) of hydrated portland cement mortar. An experimental program involving the static loading of small cement-sand beams at varying conditions of temperature and relative humidity was undertaken to obtain information on the time required for fracture. This data was analyzed with a statistical procedure developed for truncated, lognormal distributions. The results are presented as cumulative probability distributions. A stress-corrosion mechanism dependent on the presence of calcium hydroxide is postulated as a result of this study.
