| Summary: | Wood cement board (WCB) is a combination of organic and inorganic material,
wood with cement. For this experiment WCB use oil palm strands as organic
material and Portland cement as the inorganic material. The aims of this
experiment were to determine the physical and mechanical properties of the
cement board of different densities using oil palm strands with different size. For
this experiment the WCB dimension was 450mm x 450mm x 12mm. The
additive component used in WCB was aluminum sulphate (1.5%) and sodium
silicate (3%). The tests done were bending strength (modulus of elasticity (MOE)
and modulus of rupture (MOR», water absorption, thickness swelling and screw
withdrawal. The results showed that the WCB with density of 1300kg/m3 have
higher mechanical strength than 1100kg/m3 and 900kg/m3 boards. As for the
study of water absorption (WA) board with a density of 900kg/m3 with size of
30mm have highest absorption compared to others. The best mechanical
strength was for density 1300kg/m3 with 50mm strand size with MOE 1315.6
MPa and MOR 4.6 MPa. |
