# Sustainable Development Advantages of Cross-Laminated Timber (CLT) and Cross-Laminated Bamboo and Timber (CLBT)

## TL;DR

This paper reviews CLBT, a sustainable building material combining bamboo and timber, showing it outperforms traditional CLT in strength and eco-friendliness.

## Contribution

The paper introduces CLBT as a novel hybrid material with improved mechanical properties and sustainability over CLT.

## Key findings

- CLBT shows better rolling shear strength and bending stiffness than CLT due to hybrid layering.
- Bamboo integration enhances performance and promotes regional biomass use.
- Research gaps and future directions for CLBT standardization are identified.

## Abstract

As an innovative advancement beyond cross-laminated timber (CLT), cross-laminated bamboo and timber (CLBT) combines sustainability with enhanced structural performance. This review critically assesses the current state of CLBT research, focusing on its failure mechanisms, mechanical properties, and predictive theoretical models. Key findings indicate that CLBT exhibits superior rolling shear strength, bending stiffness, and stability compared to conventional CLT, achieved through optimized hybrid layering and manufacturing techniques. The integration of bamboo not only improves mechanical performance but also promotes diversification of raw materials and more efficient use of regional biomass. This paper highlights the potential of CLBT as a high-performance, eco-friendly construction material and identifies key research gaps and future directions to facilitate its standardized application.
