Abstract/Summary
Contributing to about 4% of particulate emissions, the construction industry is one of the largest polluters of the environment. In an effort to reduce emissions, BamCore has produced a dual panel wall system made of Guadua bamboo with a Douglas fir veneer. Bamboo is a highly renewable material with a fast growth rate and carbon sequestration abilities. This project investigates how heat treating Guadua bamboo influences its dimensional changes and mechanical properties for building applications. It was found that a dimensional increase in every direction occurred for all samples when exposed to higher relative humidity (50% to 90%), and that a higher temperature heat treatment decreased the overall dimensional change. Out of the four heat treatment temperatures (50°C, 140°C, 170°C, and 200°C), the 200°C heat treatment showed the most potential for decreasing dimensional change while the 50°C heat treatment exhibited the greatest change in dimension. A higher heat treatment temperature will produce more robust mechanical properties in the bamboo up to 170°C. Results suggest that the 170°C heat treatment results in the largest increase in modulus of rupture (MOR), while the control 50°C heat treatment appears to have the lowest MOR. These findings will help validate Guadua bamboo as a building material and provide BamCore with valuable information that can be used for product improvement.
