Abstract:
A survey of many State Departments of Transportation identified bond strength as the most important property of a repair material. This study focused on how moisture conditions and surface preparation of the old concrete and curing of the repaired concrete influenced the bonding of portland cement concrete and rapidset repair materials when exposed to freeze-thaw cycling. Three rapid setting repair materials were investigated and compared using a prism splitting test.
