AbstractThe present investigation confirms that delayed hydration of MgO is responsible for failure of a white-coat plaster that exhibited "bulging" nearly eight years after application. A new technique using compacts has been applied to study the unsoundness of plasters, and it is hoped to extend this method to other related building materials.
