Abstract
The aim of the research is to evaluate the feasibility of durometer for assessing setting time of the concrete by comparing it with the currently used proctor penetration test method to improve the surface finishing timing determining method generally determined based on the experience of the worker. As a research result, the correlation between suggesting method using durometer with currently used proctor penetration test method was high enough. Hence, on the surface of the concrete, the initial setting time and the final setting time could be designated as 41 HD with C-type, and 11 HD with D-type, respectively. Therefore, the durometer can be used as a portable setting time evaluation device with the easiness of handling and measuring for determining concrete surface finishing timing quantitatively.
