Grounding resistance improvement using bio-degradable recycled waste material based soil additive

Constructions expose the risk of fault current and lightning since it does not have an appropriate grounding system. In the grounding systems, the electrode affects the system reduction so that additive materials play an essential role in improving electrode resistivity. This paper conducted an experimental study on the Bio-degradable recycled waste materials to improve ground grid resistance reduction. This study contributes to the value of waste materials to improve ground grid resistance reduction. The objective is to investigate the three types of palm oil waste that behave as additive materials to enhance the performance of the grounding system by lowering the soil resistance value. This grounding system is designed from meshes of aluminum electrode material with 1m2 and 0.5m depth. The measurement is performed using the fall of potential FOP technique and recorded within 15 days. The investigated lowest resistive materials results are then compared with the results from ground enhancement material (GEM). The results are compared to give a comprehensive view of each different material advantage in improving grounding grid reduction. The results obtained show that the palm oil ashes waste has better performance in reducing grounding resistance. This study also indicates that the configuration of the aluminum meshes able to reduce grounding resistance.
