EARLY THERMAL MOVEMENT AND CRACKING OF CONCRETE. FINAL REPORT

In the past cracking at an early stage has generally been attributed to restraint of shrinkage movement. More recent research has shown that restraint of early thermal movement is the more dominant factor in the UK. This research has led to the development of a theory for the cracking of immature concrete that is different to that for mature concrete. This report is presented in six sections: 1, design brief; 2, aspects not covered by the draft department standard or advice note; 3, draft departmental standard; 4, draft advice note; 5, recommendations for further research and development work; and 6, addendum-report on cracking due to early thermal movement in the standard bridge deck designs.
