Predicting the uniaxial compressive strength of oil palm shell lightweight aggregate concrete using artificial intelligence‐based algorithms

Concern towards reducing waste disposed by Malaysian palm oil industry, palm oil fuel ash (POFA) and oil palm shell (OPS) that poses negative impact to the environment has initiated research on producing oil palm shell lightweight aggregate concrete (OPS LWAC) containing palm oil fuel ash. The present investigation looks into the effect of palm oil fuel ash content as partial cement replacement to compressive strength and acid resistance of oil palm shell lightweight aggregate concrete. Two types of mix, plain OPS LWAC and another one containing POFA as partial cement replacement have been used in this research. Cubes of 100 x 100 x 100 (mm) were water cured for 28 days before subjected to compressive strength test and acid resistance test. The findings indicate that suitable integration of POFA content would ensure occurrence of optimum pozzolanic reaction leading to densification of concrete internal structure which increases the compressive strength and better durability to acid attack. Integration of 20% POFA successfully assist concrete to achieve the highest compressive strength and exhibit superior resistance against acid attack compared to other mixes.

This paper presents of an investigation conducted the structural performance of oil palm shell lightweight aggregate concrete (OPSLAC) wall panel. Load-deflection characteristic on OPSLAC wall panel was conducted. Further, the effect of Stress-strain relationship and buckling effect on compression load was investigated. The variable selected are size of oil palm shell (OPS). Three wall panel specimens were prepared, and tests on compression load were conducted. The load-deflection result showed the changing on OPS shape used. The convex of OPS influence the bond within aggregate and cement paste. Further, the increasing of compression load is related to the formation and growth of micro cracks. As ultimate strength is approached, increased load and bulk paste micro cracks join to form continuous cracks parallel to the direction of loading on stress-stain curve. After 70% from the ultimate loading, the extent of cracking is so great that OPSLC cannot support additional load.
