Abstract

The three primary components that are utilized in the production of concrete are Portland cement, sand, and coarse aggregates. As a direct consequence of the severe lack of available materials, there is a significant increase in the demand for alternative materials (CA and FA). As a result, oil palm shells are utilized as a replacement for the chemical compound C. A for varying degrees of replacement, ranging from 0% to 100%. An investigation was conducted to determine the split tensile strength of concrete cylinder specimens at different ages and with varying amounts of replacement. despite the fact that the correlation method can’t be used to predict split-tensile strength with any degree of accuracy. The properties of strength that concrete possesses are utilized in the discovery of a correlation that was found to be more accurate.
