Controlled Low Strength Material (CLSM) is a unique and versatile material that has gained significant attention in various engineering applications. This study presents a comprehensive overview of CLSM, covering its evolution, properties, factors influencing its production and properties, mix design approach, and its wide-ranging applications. CLSM has been popularized due to its cost-effectiveness and superior performance comparison to conventional compacted fills. This study discusses the key characteristics of CLSM, including its plastic and in-service properties. The influence of various constituents, such as cementitious materials, aggregates, water, and additives, on the fresh and hardened properties of CLSM is thoroughly analyzed. The influence of curing time and temperature on the strength development of CLSM is also highlighted. The low strength and greater flowability characteristics of CLSM create possibilities for sustainable utilization of various waste resources which possess environmental issues due to their exponential growth. An in-depth exploration of the mix design approach for CLSM is presented, considering the desired engineering properties and specific requirements. This paper also delves into the wide range of applications where CLSM has been successfully employed. Certain limitations and future scopes of CLSM have been highlighted. In summary, this comprehensive review provides a valuable resource for engineers, researchers, and practitioners seeking a thorough understanding of Controlled Low Strength Material.
