Properties of Concrete - Portland Cement Association

Hardened concrete changes volume due to changes in temperature, moisture, and stress. These volume or length changes may range from about 0.01% to 0.08%. Thermal volume changes of hardened concrete are about the same as those for steel. Concrete under stress deforms elastically. Sustained stress results in an additional deformation called creep.
