Description
Summary:The rapid urbanization and industrialization of a country have created pressure on climate change. Industrial waste is a hazardous by-product produced by industrial activities. As the world moves towards sustainability era, industrial waste which is rendered useless has started to gain attention by researchers to explore the feasibility of recycling industrial waste by producing a more sustainable construction material. In view of the industrialization policy in Sarawak, the number of investors investing in the state is increasing. This will substantially increase the amount of industrial waste produced and it will in turn impose pressure and threat to the environment in Sarawak. Silicomanganese slag is a common industrial waste generated in the ferro alloy smelting plant in Sarawak. The recycling potential of silicomanganese slag is not commonly explored by researchers compared to fly ash and silica fume. This paper intends to present a review on the feasibility of recycling silicomanganese slag to produce a more sustainable construction product. A desktop study has been performed to explore the feasibility of silicomanganese slag on its engineering aspects. Results of the review indicated that silicomanganese slag has a potentiality to be recycled into a more sustainable construction product especially as alternative cementitious material. This study concluded that usage of silicomanganese slag should be explored on different types of construction products in order to promote greener construction materials. It is critical in responding the call of Sustainable Development Goals (SDGs), Goal 12 of responsible consumption and production to promote sustainable use of generated waste produced by industrial activities.
