The physical and mechanical properties of cement bonded particle board from oil palm trunk / Mohd Alif Mohd Ghazali

The effect of physical and mechanical properties by different ratio of particle for production of CBP from OPT has been studied. The ratio of particle has prepared for 1:2.50, 1:2.75, and 1:3.00. However, the percentage chemical material used in the mixture of CBP is constant which is 1%sulphate alumina AI2 (SO4)3 and Sodium silicate (Na2SiO3). The CBP has density 1300kg/m3and dimension 450mm X 450mm will cure 1month at the temperature surrounding before the sample has been tested. The process testing sample has dimension 100mm X 100mm for TS and WA, 180mm X 100mm for MOE and MOR, and 40mm X 40mm for IB. The result indicates that the physical and mechanical properties increased when the particle ratio decreased. The strongest CBP for this research is at the ratio 1:3.00 which mean the increasing amount of cement in mixture of CBP will increase the strength of CBP before reaching the optimum mixture.
