A study on structural lightweight concrete using Oil Palm Shell (OPS) aggregate
An experimental investigation using waste oil palm shell (OPS) as renewable coarse aggregate in structural lightweight concrete was conducted. An optimum OPS concrete mix with slump of 50 to 70 mm, 28-day air-dry density of about 1965 kg/m³ and 28-day compressive strength of more than 28 MPa was d...

| description |
An experimental investigation using waste oil palm shell (OPS) as renewable coarse aggregate in structural lightweight concrete was conducted. An optimum OPS
concrete mix with slump of 50 to 70 mm, 28-day air-dry density of about 1965 kg/m³ and 28-day compressive strength of more than 28 MPa was developed. The basic engineering properties which include the compressive strength, splitting tensile strength, modulus of rupture and modulus of elasticity of OPS concrete were compared with that of granite concrete (normal weight concrete). Four types of curing conditions were employed to determine its effect on the structural and durability properties of OPS concrete. The structural bond properties of OPS concrete were determined through the pull-out test incorporating different sizes and types of steel reinforcement up to an age of 180 days. The experimental ultimate bond strengths were compared with the theoretical values as per BS 8110. The flexural behaviour of OPS concrete beams was examined by testing 9 under-reinforced prototype beams under two-point loads. The experimental flexural properties such as the bending
moment, deflection and cracking characteristics were compared with the design code provisions of BS 8110 and ACI 318, and these codes gave reasonable estimates of
the experimental values. Other flexural properties namely the ductility, end rotation and strain development were compared to that of other lightweight concretes. In
terms of durability, the water permeability, water absorption, volume of permeable voids (VPV) , sorptivity, 90-day salt ponding, cyclic wetting and drying, and rapid
chloride penetration test (RCPT) of OPS concrete were investigated. These durability properties were also compared with the work of other researchers. This experimental
investigation confirmed that OPS concrete performed similarly to other structural lightweight concretes. The results obtained from this investigation provided a critical
understanding on the performance of OPS concrete, thereby confirming that OPS
can be used as coarse aggregates for structural lightweight concrete. |
