Abstract

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.
