LTRC Completes Internal Curing Evaluation

The Louisiana Transportation Research Center (LTRC) has completed an evaluation of Internal Curing for Louisiana's concrete transportation structures.

The study included both laboratory testing and field evaluation of two bridge projects. Two field trial placements for bridge deck concrete were conducted, one in North Louisiana on U.S. 80 near Ada and the other in Western Lafayette Parish on West Congress Street (pictured at left). The results of the investigation have been published in LTRC Report 569: Evaluation of Portland Cement Concrete with Internal Curing Capabilities.

Conclusions:

The report concludes that internal curing reduces cracking, improves cement hydration, which will result in more durable structures, and includes recommendations for implementation by Louisiana Department of Transportation in the state's bridge construction and other transportation structures.
