The Committee conducted research to elucidate the current state of test methods to confirm the certainty of construction execution. Availabilities of the test methods to assess that the performance of placed concrete actually meets the designed performance was investigated. Test methods to evaluate the property of concrete and their adequate timing to be applied in each execution stages were also researched/ Furthermore, a questionnaire survey was conducted a d summarized particularly regarding new test methods to evaluate the properties of concrete and test methods to confirm of various specifications agreed upon before execution are actually secured. Field tests were conducted as well to investigate the effect of execution on the in-situ qualities of concrete.
