Abstract: The thermal properties of oil palm shell (OPS) are investigated to determine if it could be used as a lightweight aggregate for a concrete mixture. The thermal conductivity, diffusivity, and specific heat were all tested through the Hot Disk transient plane source (TPS) method, with a TPS 2500. The thermal conductivity and diffusivity both increased as the volume fraction of OPS increased. This is because OPS is very porous which gives it an inherently low thermal conductivity and diffusivity. The specific heat measurements were inconsistent, this is because of the random distribution of aggregate.
