Field Evaluation of Internally Sealed Concrete
Portland cement concrete containing wax beads was evaluated by laboratory testing. Details of the testing and construction of a bridge deck of internally sealed concrete are reported. An evaluation of performance of the deck concrete was made after a little more than three years of service. The deck was found to be badly cracked. From cores, it was determined that the cracks extended at least to the reinforcing steel, and in some cases, entirely through the 8-1/2 inch deck. It is concluded from an examination of the cracked faces of cores that cracking was probably caused by shrinkage of the fresh concrete due to some slight delay in curing. A dry wind was blowing during concrete placement, creating adverse curing conditions.
