Potential Use of Waste Marble Powder as an Adhesive Filler in the Manufacture of Laminated Veneer Lumber

Abstract

The waste powder occurring during the manufacture of marble, which is preferred a lot in the construction sector, has been the cause of environmental pollution to a significant extent in recent years. The reutilization of marble waste powder would provide a contribution to the protection of nature. The potential usability of waste marble powders as an additive substance in the manufacture of wood-based panels was investigated in this study. With this objective, laminated veneer lumber (LVL) panels were manufactured by adding marble factory waste powders in different ratios to polyvinyl acetate (PVAc) and urea-formaldehyde (UF) adhesives. The waste powders of beige marbles and travertine marbles were mixed by weight with adhesives in the ratios of 0%, 10%, 20%, 30%, 40% and 50% (by weight). Physical and mechanical tests were performed on the specimens obtained from the LVL panels. According to the results obtained from the present study, while a very high resistance was obtained with the waste beige marble powder at high ratios of mixture and with the waste travertine marble powder at low ratios of mixture with the PVA adhesive, a poor performance was displayed for the travertine powder with the UF adhesive.
