Creep and Shrinkage of Reinforced Thin Shell Concrete.

Abstract:

The report presents some results of an experimental program to determine creep and shrinkage of thin-shell reinforced concrete. The ultimate objective is to develop relationships that will permit prediction of creep and shrinkage of concrete shell elements or structures in any environment. To accomplish the objective, creep and shrinkage tests are being performed on prismatic specimens of normal weight and also of lightweight concretes. Parameters include variations in each of the following concrete mix designs, percentage of steel mesh reinforcement, relative humidity, specimen size, and stress-strength ratio. Data presented in this report enables construction of SV ratio of exposed surface area to volume charts for prediction of creep and shrinkage of full-size, thin-shell members of similar concrete.
