SHRINKAGE AND CREEP OF HIGH-, MEDIUM-, AND LOW-STRENGTH CONCRETES, INCLUDING OVERLOADS

The influence of drying and of sustained compressive stresses, at and in excess of the normal working stress levels, on the shrinkage and creep properties of high-, medium-, and low-strength concretes were experimentally studied and compared. The 28-day compressive strength of the materials studied ranged from 3000 to 10,000 psi (21 to 69 MPa). The long-term shrinkage was found to be greater for low-strength concrete and smaller for medium- and high-strength concretes. Creep strain and normalized creep were smaller for high-strength than for concretes of medium and low strengths. The creep-stress proportionality limit (as a percent of fc) was higher for the high-strength concrete than for the others by about 20 percent. Data on creep recovery for the three materials are also presented.
