Abstract

Concrete is an important and widely used constructional material because of its excellent combination of desirable properties, but it is subject to appreciable volume changes which may, under certain circumstances, cause rupture or may aid the action of destructive agents through the development and growth of cracks. Volume changes in concrete due to variations of temperature, humidity, and stress are partly or entirely reversible, but volume changes due to destructive chemical and mechanical action are not reversible and are cumulative as long as the action continues.
