Manufacture of particleboard based on cement bag and castor oil polyurethane resin

This study assesses the potential of cement packaging residues from building site wastes to produce particle boards. Panels with 0.4, 0.5 and 0.6 g cm(-3) and 15% of castor resin content were produced and its chemical, physical, mechanical and microstructural were analyzed. The results revealed that the packages have a high cement content and low lignin pulp. Furthermore, the increase in density reduced the physical properties while enhanced mechanical properties, being the 0.6 g cm(-3) particleboards the only formulation with potential to produce particulates. Thus, the packaging of cement becomes an option for the manufacture of particle board. (C) 2015 Elsevier Ltd. All rights reserved.
