The properties of Cross Laminated Timber (CLT): A review

Abstract

Cross laminated timber (CLT) is a structurally efficient construction material that has gained widespread recognition for the possibility of quick assembly. This review paper enquires into the crucial factors that influencing the bonding and mechanical properties of CLT, with a focus on optimizing its performance. The bonding properties are examined, emphasizing the types of adhesives used, adhesive spread rate and clamping pressure during the manufacturing process. These factors significantly impact the integrity and durability of the CLT structure. The mechanical properties, another critical aspect of CLT, are explored in detail. The review explores the relationship of various factors such as wood density, anatomical properties, wettability and surface roughness, shedding light on their profound influence on the overall structural performance of CLT. The long-term performance of adhesive and durability of CLT are also discussed. Understanding and effectively managing these factors are imperative in ensuring the reliability and effectiveness of CLT as a construction material. By providing a comprehensive overview of the factors affecting CLT properties, this review aims to guide researchers, engineers, and industry professionals in optimizing the manufacturing processes and design considerations. Ultimately, a thorough understanding and management of these factors will contribute to the continued evolution of CLT as a sustainable and reliable solution for modern construction.
