Abstract:
With a view toward application in structural engineering, a laboratory investigation is in progress regarding the influence of size and shape of member on the shrinkage and creep of concrete. This paper reports test data obtained during the first 4 years of observation. Measurements have been made of shrinkage and creep, at 70F and 50 percent relative humidity, of concrete cylinders ranging in diameter from 4 to 24 in., and of l-shaped members with depths from 1 1.5 to 46 in. The creep specimens were loaded to about 25 percent of their compressive strength. It is concluded that the Volume surface ratio is a suitable parameter for use in structural design when estimating the influence of size and shape of member on shrinkage and creep deformations.
