Bamboo composites for construction

Bamboo is a fast-growing and sustainable raw material. © Singapore Republic Polytechnic The market for fibre-reinforced polymer reinforcing bars (rebars) is expected to grow at 11.4% a year in the next five years, but for this market materials such as glass and carbon are expensive as an alternative to metals.

As a potentially new product, researchers at Singapore Republic Polytechnic, working with ETH Zürich in Switzerland, have been developing a new adhesive for maximizing the bonding between bamboo composites and concrete. The work was recognised with an Innovation Award at the recent JEC Asia exhibition held from November 15-17 in Singapore.

Bamboo is a fast-growing and sustainable raw material that grows in abundance in the tropical belt, making it cheaper than other materials.

The development of the new adhesive coating makes it possible to bond bamboo composites with the necessary strength-to-weight ratio and corrosion resistance properties in concrete, while improving the water resistivity of the material and opening up potential for its use in use in structural applications such as rebars.
