To reuse waste concrete form plywood (hereafter, waste plywood) as core of plywood, the author investigated various properties of waste plywood. A significant positive correlation between the density and shear strength was evident in the cyclic boiling test in the case of new plywood, but the correlation was low in the case of waste plywood. The EB0 (MOE parallel to grain) of waste plywood was lower than that of new plywood, but EB90 (MOE perpendicular to grain) was equal to that of new plywood. Therefore, there was no deterioration of bending properties of waste plywood in crossband and core veneer.
