In this study, we compared the proctor penetration resistance test value of the concrete using CGS for Fine Aggregate and the hardness value of the Durometer. The results are summarized as follows. 1) Surface finish The Durometer C type setting time measurement value was about 45 HD, and the hardness value of the Durometer D type was about 5 HD. 2) The proctor penetration resistance test value and the hardness value of the Durometer are highly correlated and are expected to be easy to use.

In this study, the correlation with a proctor penetration resistance tester is analyzed for the purpose of judging the setting time of concrete by the convenient portability of the durometer which is a rubber hardness meter.The result of this study showed a high correlation between the value of the tilt of the durometer and the measured value of the proctor penetration resistance tester.

In this research, Proctor insertion resistance test values and Durometer A type hardness values were compared and analyzed between the setting times of the concrete using CGS for Fine Aggregate, and the results are summarized as follows. 1) The Proctor penetration resistance test value and the hardness value of Durometer A type showed a high correlation in the form of a curve. 2) About surface finish The resolution exceeding the hardness value of the Durometer A type uses about 25 HD, and in the case of termination, about 35 HD, and is considered to be effective for determining the surface finishing work time. The possibility to do is expected.
