The purpose of study was to clarify the quality of plywood for concrete formwork with reuse of forms and the finish of concrete surface using reused plywood. In this study, an experiment on influence of reuse (up to 4 times) of plywood for conventional formwork at building construction site was carried out. Regarding the influence of reuse on the quality of plywood, bending strength, bending Young’s modulus, and surface roughness were investigated. In addition, the influence of reused plywood on gloss, color unevenness, and water absorption of the concrete surface was investigated. Moreover, in order to confirm the influence of reuse of plywood at construction site, the results of this experiment at building construction site were compared with the results of laboratory experiment conducted so far.
