Response of load-displacement on cubical sample of Oil-Palm shell with fly ash concrete using digital image correlation system

Abstract

Oil-Palm industry produces some side products as solid waste which consist of 23% empty oil palm bunches, 6.5% oil palm shell, and 13% fiber from the main products. Reusing oil palm waste is very important to increase economic value and reduce potential pollution. One of the ways to exploit Oil Palm Shell (OPS) byproduct is to substitute the uses of natural coarse aggregate in concrete structure as building material. Study on the use fly ash as one of the admixtures to increase OPS concrete compressive strength has been conducted. Digital Image Correlation (DIC) as a method of displacement response measurement was applied. Fujifilm XA-3 was used as primary camera to capture the image with speed of 3 frames per second (fps). An open source 2D-DIC, Ncorr v1.2 and MatLab student version of R2020a were used. The obtained average compressive strength is 25 MPa, the average of stiffness of the specimens is 946.95 kN/mm and the average of Poisson Ratio is 0.22 (range 0.21-0.22).
