Abstract

Abstract

Cracking control in massive concreting has been a conventional but complicated problem.Since the very early application of massive concrete,researchers have been studying the cracking mechanism and methods to control them.It has been well known that concrete cracking is resulted from temperature changing (differential temperature) and cement hydration.However,to study and control the cracking by integrating the temperature with hydration mechanisms is a new topic.This paper presents an integrated stress control method based on the study which integrates the temperature with hydration mechanisms.The research result has been applied successfully to foundation concreting for a number of nuclear power plants.
- thermal stress,
- shrinkage stress,
- balance of stress,
- constraints of boundary
