Utilisation of oil palm trunks for cement-bonded particleboard manufacture

A comprehensive study was carried out to make use of oil palm trunk OPT fibres as wood aggregate for cement-bonded particleboard CBP manufacture. Several problems related to harvesting transporting and processing were identified. However the major setback was the high sugars and starch contents in this monocotyledon species. The presence of high amount of carbohydrates in the wood aggregate considerably affected the physical and mechanical properties of CBP produced. Hydration test showed that fresh OPT fibres had significantly delayed the setting time and decreased the hydration temperature of Portland cement. The hydration properties of wood-cement mixtures was improved when the water-soluble components were extracted out from the OPT fibres. Soaking and piling storage of OPT chips and flakes reduced the amount of sugars at a faster rate compared to storing OPT in the log or plank form. A total of 14 series of CBP were made from OPT wood flakes pre-soaked in water and piling storage for a period of 0-14 days. Results showed that CBP produced from OPT flakes pre-soaked in water had better mechanical and physical properties compared to those produced from OPT flakes stored in piling form.

Abstract

A comprehensive study was carried out to make use of oil palm trunk OPT fibres as wood aggregate for cement-bonded particleboard CBP manufacture. Several problems related to harvesting transporting and processing were identified. However the major setback was the high sugars and starch contents in this monocotyledon species. The presence of high amount of carbohydrates in the wood aggregate considerably affected the physical and mechanical properties of CBP produced. Hydration test showed that fresh OPT fibres had significantly delayed the setting time and decreased the hydration temperature of Portland cement. The hydration properties of wood-cement mixtures was improved when the water-soluble components were extracted out from the OPT fibres. Soaking and piling storage of OPT chips and flakes reduced the amount of sugars at a faster rate compared to storing OPT in the log or plank form. A total of 14 series of CBP were made from OPT wood flakes pre-soaked in water and piling storage for a period of 0-14 days. Results showed that CBP produced from OPT flakes pre-soaked in water had better mechanical and physical properties compared to those produced from OPT flakes stored in piling form.
