As a country that contributes to 85% of the world’s crude palm oil, Indonesia produces enormous amounts of waste-by-products (ex: oil palm shells, fiber, etc.) with its potential to be processed into other useful products, including construction material substituent. Previous studies have shown that the use of oil palm shell as a concrete aggregate substituent can produce lightweight concrete that achieved the structural concrete strength requirements. Nevertheless, a further robust computational model on OPS concrete towards regular concrete using concrete damage model is to be characterized using finite element code CAST3M. OPS concrete’s parameterization is conducted based on concrete cube compression tests using digital image correlation (DIC). The average modulus of elasticity obtained is similar to lightweight concrete. The compression strength obtained is 20.33 ± 1.19 MPa, and the split-tensile strength is 1.23 ± 0.19 MPa.
