From page 22...
... A number of tests are recommended for evaluation of EOT concrete mixtures. 5.1 TEST METHODS 5.1.1 Testing Fresh Concrete Testing of fresh EOT concrete entails measuring workability, air content, and maturity.

From page 23...
... It has been found that an adequate air-void system can be difficult to achieve in EOT concrete, even when the air content of the fresh concrete was satisfactory. Thus, if durability problems have been observed in EOT concrete repairs, an agency should consider measuring the air-void system parameters of the concrete.
