A Preliminary Study On Chemical And Physical Properties Of Coconut Shell Powder As A Filler In Concrete

Abstract

Abstract Coconut Shell Powder were obtained from coconut shell that had been discarded and grinded until it become in a form of powder. This study were conducted to determine the chemical and physical properties of coconut shell powder to be used as a filler inside concrete. In order to do that, an experimental setup of X-Ray Fluorescence (XRF), Particle Size Distribution, Scanning Electron Microscopic (SEM), Density, and Specific Gravity were conducted. The coconut shell powder consist mostly carbon (C) and potassium oxide (K 2 O). The presents of silicon dioxide (SiO 2 ) is crucial in order to be mix with concrete. The size of the coconut shell is ranging from 600 μ m and below. From all the testing, it is show that the coconut shell powder can be use in mixing with concrete as a filler.
