Sewage sludge is byproduct of wastewater treatment that can pose a significant disposal challenges for Municipal authorities. However, it is also has potential as a construction material due to its low cost and unique properties. This abstract provides an overview of the current state of knowledge on the use of sewage sludge as construction material, including its applications and environmental impacts. The abstract present review of existing literature on the topic, including case studies and experimental data, to assess the potential benefits and risks of using sewage sludge in construction. The abstract also highlights the need for further research to fully understand the implications of these practices and to develop best practices for it implementation. Concrete, being the most widely used construction material worldwide, has a significant environmental impact due to its extensive consumption of natural resources and high carbon emissions. To address these challenges, researchers have explored various sustainable alternatives, one of which is incorporating sludge, a byproduct of wastewater treatment plants, into concrete production. This abstract presents a comprehensive overview of the utilization of sludge as supplementary cementations material (SCM)in concrete, highlighting its potential benefits and challenges. Sludge, rich in organic and inorganic compounds, possesses properties that can enhance the performance of concrete. As a SCM, It can partially replace cement thereby reducing its demand and minimizing the carbon footprint associated with cement production. Additionally, sludge in corporation in concrete promotes waste management and offers a sustainable solution for the disposal of this abundant by product. The abstract examines the effects of sludge on various concrete properties, including workability, strength development, durability and environmental impacts. Studies have shown that sludge addition can enhance the workability of fresh concrete, leading to improved cohesiveness and reduced water demand. Furthermore, the pozzolanic and filler effects of sludge contribute to the strength development of hardened concrete, with potential improvements observed in both early age and long term strengths. Moreover, the inclusion of sludge in concrete can enhance its durability performance, such as resistance to chloride ion penetrates Sulfate attack and alkali silica reaction. The abstract also discusses the potential environmental benefits, including reduced carbon emissions, energy saving and conservation of natural resources, resulting from sludge utilization in concrete production. Overall , in corporation sludge into concrete presents a promoting opportunity to enhance the sustainability of the construction industry; further research and development efforts are required to fully understand the long term performance and environmental implication of sludge-based concrete and to overcome the associated challenges. By embracing sludge as valuable resources, the construction sector can move towards a more circular economy and contribute to a greener and more sustainable future.
