In this era of globalization, the utilization of construction materials in the construction sectors are increasing annually with the high demand of infrastructure due to various aspects. As the whole world are now looking forward for more inventive production to be in line with the initiative for scoring the Industry 4.0 (the fourth industrial revolution), it will same goes to the construction industries. There a lot of initiative has been made encapsulates future industry development trends to achieve more intelligent manufacturing processes, including reliance on ecosystem, in terms of design, construct and manufacturing. It can be referred to the potential material from the production or manufacturing waste to be beneficial as part of material replacement in construction. It would be the right timing as the amount of waste produced through coal-fired power plant incineration process such as fly ash and bottom ash are increasing and dumped in landfill, which may cause environmental issue. The fly ash has been commonly used by integrating it into cement mixture design, bottom ash has not been commonly used in the industry. Thus this research has been conducted to analyze the performance of adding bottom ash into Controlled Low-Strength Material (CLSM). Bottom Ash (BA) material has been added into dry Cement (C) mix in three different batches with different ratio of C/BA of 3.0, 1.0 and 0.33. The fiowability test, unconfmed compressive strength and pH test were carried out and the results were discussed. The flowability of CLSM achieved the spread diameter ranged from 20 to 24cm, showing that the utilization of bottom ash partially replacing cement do not cause major effect on the flowability but greatly influenced by the amount of water added. With the addition of bottom ash, CLSM do not possess corrosivity with pH level ranged from 8-12. Compressive strength of the CLSM mix design ranged from 3.52 to 877 MPa, indicating the suitability of fhe CLSM to be used in non-strucmral filling below foundations and slabs. It can be concluded that me potentiality of industrial waste bottom ash material to be recycled and reused as a backfilling material in ground structures to ease the construction work in confined areas is high and practically attainable. © 2022 American Institute of Physics Inc..
