Development of bamboo reinforced cement bonded particle board

Abstract

This work was undertaken to examine the compatibility of bamboo particles and their bonding with Portland cement for bamboo-reinforced cement-bonded particle board. Pozzolana Portland cement was used as a sizing agent. The amount of bamboo particles was taken on an air-dry basis of cement. Sodium silicate (Na₂SiO₃) and aluminium sulphate [Al₂(So₄)₃] were used to prevent the heat of hydration and increase the rate of cement setting, respectively. Different ratios of cement and bamboo particles were used to study the properties of the particle board. The physical and mechanical properties of Bambusa bambos bamboo reinforced cement bonded particle boards were evaluated. The density of the boards varied between 1.28 g/cm³ to 1.36 g/cm³ in 2.0:1.0 and 3.0:1.0 cement: particle ratios, respectively. The moisture content of the boards was 9.96 %, 6.98 % and 6.62 % for 2.0:1.0, 2.5:1.0 and 3.0:1.0 ratios of cement: particle, respectively. The physical properties of the board, such as density, moisture content, water absorption and thickness swelling decreased with an increase in the cement: bamboo particle ratio. The maximum MOR and MOE were 9.17 N/mm² and 4884 N/mm², respectively in 3.0:1.0 cement: bamboo particle ratios. The mechanical properties of the boards such as tensile strength, modulus of rupture (MOR), modulus of elasticity (MOE) and screw withdrawal were increased with an increase in the cement: bamboo particle ratios. The 2.5:1.0 and 3.0:1.0 cement: bamboo particle ratios performed best for cement-bonded particle boards and also passed the IS: 14276 standard. These cement-bonded particle boards can be used for partitioning, wall cladding, flooring, false sealing, kitchen cabinets and other purposes.
