Emerging Tenera oil palm shell concrete: Mix design and cost analyses

Abstract The utilization of oil palm shell (OPS) in concrete dates back since four decades ago. While most research has only been done on the Dura-OPS as coarse aggregate concrete, few Tenera-OPS. Tenera-OPS is obtained by a hybrid crossbreeding between Dura and Pisifera type fruits to obtain thinner fruit produce 30% more oil. different physical properties compared Dura-OPS, which could alter mechanical behaviour concrete. Therefore, this paper studied mix designs (Tenera-OPSC) investigate its characteristics, compressive strength those Dura-OPSC from literature. It found that 20.24 MPa be produced with very high cement content 1050 kg/m 3 . This study shown Tenera-OPSC reduced 55 – 72% using common acceptable design used for Dura-OPSC. swells shrinks during hardening process causes de-bonding matrix, believed main reason lower strength. A cost analysis was also compare costs normal weight (NWC) similar grade. 2% than NWC.
