Abstract:
In common usage, the term shrinkage is a shorthand expression for drying shrinkage of hardened concrete exposed to air with a relative humidity of less than just under 100 percent. This paper describes the concomitant effects of hydration: development of strength, development of heat, and reduction in the volume of hydrating cement paste system (autogenous shrinkage). Plastic shrinkage, drying shrinkage, autogenous shrinkage, and thermal shrinkage are discussed with particular reference to their effects in various types of structural elements made with high-performance concrete.
