Review on Cross Laminated Timber in Modular Construction

Cross-Laminated Timber (CLT) is an innovative and sustainable building material that has gained significant traction in recent years, especially in modular construction. Modular construction is presented as a method that involves prefabricating building components or modules in a factory setting, which are then transported and assembled on-site. This approach reduces construction time, minimizes waste, and improves quality control, making it a compelling option for modern construction projects. This paper aims to provides a comprehensive review of CLT in modular construction. The paper begins with a brief introduction and definition of CLT, standards, and manufacturing processes. It highlights the production of finger-jointed lamellas, types of adhesives, and the steps involved in composing, pressing, cutting, and joining CLT panels. The report further explores the advantages of using CLT, offering insights into its benefits, such as strength, sustainability, and speed of construction. The concept of modular construction is then introduced, outlining its definition and benefits over traditional on-site construction. The synergy between CLT and modular construction is a focal point, with discussions on why CLT is advantageous in modular systems and the detailed steps involved in modular CLT building construction. Key aspects like transportation and connections are examined. An overview about experimental analysis provides an evaluation of CLT’s performance under various conditions, including, fire resistance, and seismic performance. Case studies of notable projects utilizing CLT in modular construction, are presented to showcase real-world applications. This review journal aims to provide a detailed understanding of CLT, also its role in modern construction, emphasizing its potential to revolutionize the building industry through innovative and sustainable practices.
