Abstract

This study attempts to find a correlation between the hardness of the set meter and from analyzing the field applicability, to propose a scientific setting time determination method when working on concrete surface finishing. The results indicated that surface finish time management is possible if the concrete surface finish work at the site manages to start at the initial time before and after 45HD of the set meter hardness. Further analysis is needed to collect enough data to statistically process at more work sites to prove its effectiveness. Overall, if the concrete surface finishing work hours reach a consensus in practical application, it could contribute to the transformation of quality scientific management.
