Deflection and crack control of composite beams from rubber timber and palm oil waste / Wan Kassim Tuanku Zubir and Mohd Rosli Shafie

This experimental project is an investigation of deflection and crack control of Composite T-Beams made of rubber timber and concrete using palm shells, the two most abundant raw materials in Malaysia. Initially rubber trees big enough to provide the required size of beams were searched. The RRIM, Sungai Buioh recommended to use two clones but only the seedling type was suitable and for this purpose TJ1 seedling was selected. With the courtesy of FRI, Kepong they were cut into beams and given nominal treatment and air-dry seasoned.
