摘要：

Currently, the trend of using recycled construction materials is increasing globally to achieve sustainable development. The utilization of industrial waste in producing concrete with compliments of technology advancement is mostly carried out. This study examines the use of recycled industrial timber aggregate (RITA) as aggregate replacement in producing concrete slab. There are two types of concrete slabs specimens namely RCS1 (Fiber Glass-Reinforced) and RCS2 (Polyvinyl Chloride Pipe-Reinforced) were experimented. The strength development of RITA aggregate concrete slab were be determined. The serviceability limit state of the specimens was also studied. Superplastisizer was added to achieve the concrete workability. The test results were recorded at the age of 7, 14 and 28 days respectively. The result showed that higher percentage of RITA aggregate use tends to reduce the concrete strength. The replacement of 30% RITA aggregate reinforced with polyvinyl chloride pipe and E-Class glass fiber performs low strength development compared with normal concrete slabs. The deflection of the concrete slabs performs a linear relationship with the load applied. The preliminary findings demonstrated that 30% RITA aggregate has good potentials as partial aggregate replacement in concrete slab construction combined with E-Class glass fiber or polyvinyl chloride pipe(PVC).
