Abstract
The study investigated the flexural strength of concrete using Pili nut shells (PNS) as partial replacement for coarse aggregates. Using a 0.5 water-to-cementitious material ratio, five rectangular specimens with dimensions of approximately 400mm, 100mm, and 100mm, in length, width, and height, respectively were produced for each percent replacement (from )% to 20%)with increments of 5% using 0% as the control. After mixing, it was found out that the slump or the workability of fresh concrete decreases as the amount of PNS aggregates increases. In addition,, the density f the concrete had an inverse relationship with the increasing amount of PNS aggregates. The 205 replacement of PNS was not able to yield a lightweight aggregate (concrete (LWAC). Though the strength of concrete decreased up to 10% and increased up to 20%, there were no significant differences between the average strengths per replacement versus the control.
