Effect of Ambient Temperature and Humidity on Creep and Shrinkage of Concrete

The effect of ambient temperature and humidity to which concrete is exposed prior to or during loading should be taken into account, when creep and shrinkage are predicted. This paper attempts to clarify the effect of ambient temperature and humidity on the creep and shrinkage of concrete. Creep and shrinkage tests were carried out under constant and varying histories of temperature and humidity. Creep and shrinkage tests subjected to ambient temperature and humidity were also carried out in a room where the effect of rain and wind were negligible.
