“…It has been reported that mechanical properties such as compressive strength, splitting tensile strength, flexural strength and modulus of elasticity of oil palm shell lightweight concrete (OPSLWC) are lower than other lightweight aggregate concrete (LWAC) [ 10 , 11 ]. Therefore, the incorporation of discontinuous fibres (polyvinyl alcohol, polypropylene, nylon and steel) into OPSLWC has been proposed to improve concrete mechanical performance [ 12 , 13 , 14 , 15 , 16 , 17 , 18 ]. According to thr previous studies, the inclusion of highly dense metallic fibers effectively enhanced the mechanical properties, but it also significantly deteriorated the workability and caused an increment in density, which does not favor the development of LWC [ 19 , 20 ].…”

Oil palm shell (OPS) is an agricultural solid waste from the extraction process of palm oil. All these wastes from industry pose serious disposal issues for the environment. This research aims to promote the replacement of conventional coarse aggregates with eco-friendly OPS aggregate which offers several advantages, such as being lightweight, renewable, and domestically available. This paper evaluates the mechanical and thermal performances of renewable OPS lightweight concrete (LWC) reinforced with various type of synthetic polypropylene (SPP) fibers. Monofilament polypropylene (MPS) and barchip polypropylene straight (BPS) were added to concrete at different volume fractions (singly and hybrid) of 0%, 0.1%, 0.3% and 0.4%. All specimens were mixed by using a new mixing method with a time saving of up to 14.3% compared to conventional mixing methods. The effects of SPP fibers on the mechanical properties were investigated by compressive strength, splitting tensile strength and residual strength. The strength of the oil palm shell lightweight concrete hybrid 0.4% (OPSLWC–HYB–0.4%) mixture achieved the highest compressive strength of 29 MPa at 28 days. The inclusion of 0.3% of BPS showed a positive outcome with the lowest thermal conductivity value at 0.55 W/m °C. Therefore, the results revealed that incorporation of BPS fiber enhanced the performance of thermal conductivity tests as compared to inclusion of MPS fiber. Hence, renewable OPS LWC was proven to be a highly recommended environmentally friendly aggregate as an alternative solution to replace natural aggregates used in the concrete industry.

“…Although, the earliest record of investigation into reinforcing concrete with oil palm fibers (OPF) was in the 1980s [1], it has recently attracted interest due to increasing level of awareness of the importance of environmental sustainability. Fibers obtained from all parts of the oil palm have been investigated for possible use in construction [24,[37][38][39][40][41][42][43][44][45][46][47] and previous studies have carried out investigations on the engineering properties and possible applications of these fibers [20,[39][40][41][48][49][50][51][52][53][54][55][56]. However, there have been inconsistencies in the experimental methods employed, and values reported in various studies on properties of the fiber.…”

Fibers obtained from different parts of the oil palm tree (Elaeis guineensis) have been under investigation for possible use in construction. Studies have been carried out investigating the engineering properties and possible applications of these fibers. However, the experimental methods employed and the values of mechanical and physical properties recorded by various authors are inconsistent. It has therefore become necessary to organize information which would be useful in the design of oil palm fiber cement composites and help researchers and engineers make informed decisions in further research and application. This review provides information about fibers from different parts of the oil palm, their properties, enhancement techniques, current and potential application in cement composites.

“…Fibre Reinforced Concrete (FRC) is a high-performance material for both the construction and reinforcement of structural elements exposed to impacts and other types of extreme loads. Many studies refer the benefits of fibres incorporation in concretes exposed to explosions [1][2][3][4], ballistic shocks [5], cyclic loads [6], and different types of impact [7][8][9]. Numerous methods to evaluate the FRC impact resistance have been proposed, such as the oscillating pendulum (Charpy type) [10], pressure bar (Split-Hopkinson) [11], rotating machine [12], ACI committee 544 drop weight test [13], and other different drop-weight impact tests [14,15].…”
