Rapid-setting materials for patching of concrete.

The use of rapid-setting materials for patching portland cement concrete pavements and bridge decks has increased greatly during the past several years. This report of the Transportation Research Board reviews information presently available on the performance of such materials. Patch materials evaluated fall into eight groups: 1) portland cement, 2) other chemical-setting cements, 3) thermo-setting materials, 4) thermoplastics, 5) calcium sulfate, 6) bituminous materials, 7) composites, and 8) additives used to alter mix characteristics. Recommendations for further study are also included. /Author/.
