The influence of cement-wood particle ratio and type of accelerator on physical properties of Falcataria moluccana (MIQ) Barneby & J.W. Grimes
Abstract
Cement-bonded particle board is composed by wood fibers or particles and cement to produce a robust and adaptable board. The board has some essential functions and attributes such as excellent wear resistance and durability, moisture resistance, strong fire resistance, high sound insulation qualities, and as a thermal insulation. This study aimed to analyze the effects of the cement/wood particle ratio and the type of accelerator on the physical properties of cement-bonded particle board made from Sengon (Falcataria moluccana (MIQ) Barneby & J.W. Grimes) wood. The boards were prepared form the variation of cement/wood ratios (70/30, 60/40, and 50/50 w/w) and two types of accelerators (MgCl2 and CaCl2). The target density and thickness of the board were 1.2 g/cm3 and 12 mm, respectively. The wood particles were boiled at 100°C for 30 min. The physical properties of cement plates were evaluated according to ISO 8335:1987. The results showed that the board using both MgCl2 and CaCl2 accelerators reached hydration temperatures higher than the controls, with values of 54°C (9th hour) and 59°C (sixth hour), respectively. We found that Sengon wood possessed great potential in the production of cement-bonded particleboard. Statistical analysis showed that most treatments in this study caused significant difference according to the physical properties tested (thickness, density, thickness swelling and water absorption). The greatest properties were achieved from enhanced cement/particle ratio and CaCl2 accelerator.
