CURING COMPOUNDS FOR PORTLAND CEMENT CONCRETE

New concrete curing compound formulations were developed which have properties superior to the wax- or wax-resin base materials formerly used. The new compounds are made from chlorinated rubber or hydrocarbon resin. Two new test methods were also developed and have been adopted. In the water retention test, curing compounds can now be accepted after 24 hours of testing in lieu of the 72 hours formerly required. The second test method describes a means of measuring the spread rate of curing compounds. Alternate test methods to the two which were adopted are also described; however, further study would be necessary before implementation. Specifications and test methods are included in the appendix.
