Effects of treatment for raw oil palm shell on compressive strength of oil palm shell concrete

This paper presents test results of thirty-two OPSC (Oil Palm Shell Concrete) cubes cast with OPS (Oil Palm Shell) under different treatment condition and with different cement content. The study concludes that OPSC cast using fully treated (Wash-Dry-Sieve) OPS yields the highest compressive strengt...

Description
Summary:This paper presents test results of thirty-two OPSC (Oil Palm Shell Concrete) cubes cast with OPS (Oil Palm Shell) under different treatment condition and with different cement content. The study concludes that OPSC cast using fully treated (Wash-Dry-Sieve) OPS yields the highest compressive strength, an increase of 65% in comparison with using untreated OPS. The increase in strength can be attributed to 1) Removal of residual oil on OPS surface via washing with detergent, mass 2% of the dry OPS mass, and 2) Removal of sub-2mm particles in OPS via sieving comprising of soil and OPS fibres. OPSC can develop compressive strength at a higher rate with washing, drying and sieving treatment performed on OPS compared with concrete cast with untreated OPS.
