CONCRETE CURING PRACTICES IN THE UNITED STATES
A survey is reported of 50 state highway departments in the U.S., and the results are discussed. The results showed that concrete curing practices need to be standardized, specifications need to be clarified and written in more meaningful terms, and test methods used to evaluate the effectiveness of curing materials need to be improved. It was found that membrane-forming curing compounds are the most widely used materials for curing. About 77% of the states use ASTM C 156, a test procedure that is not entirely reliable for evaluating curing compounds. Most of the states advocate putting more effort into curing bridge decks. Almost all states use the specification of a minimum coverage rate as the primary means of insuring good curing; and the minimum curing period specified by most states seems too short. The need is emphasized for reviewing specifications and test procedures, and for educational programs on the curing of concrete.
