Abstract

The compressive strength of concrete, with Coconut Shell Aggregate (CSA) as coarse aggregate, was studied with varying moisture conditions: Saturated Surface Dry (CSA-SSD), No Treatment (CSA-NT), and Dried (CSA-D). The compressive strength of concrete was determined based on ASTM C39. The specimens contained 100% replacement of the coarse aggregate using CSA. The water-to-cement ratio used was 1:2. It was found that the substitution of CSA as coarse aggregate lowered the density of the concrete specimens to 70-80% but has developed lower compressive strength compared to normal concrete with gravel coarse aggregates. The compressive strength of the samples varied depending on the moisture treatment on the CSA ? where the drier the CSA, the higher the compressive strength developed and vise-versa.
