PPT-Shrinkage and Cracking Behavior of HPC Used for Bridge Deck

By Hasitha Seneviratne Iowa State University 2013 Introduction Objective To examine the shrinkage and cracking potential of HPC concrete overlay mixes Different cements Supplementary materials. These cracks appear mostly on horizontal surfaces They are usually parallel to each other on the order of 1 to 3 feet apart relatively shallow and generally do not intersect the perimeter of the slab Plastic shrink age cracking is highly likely to o VIRGINIA CONCRETE CONFERENCE.
