Geotechnical characterisation of recycled biopolymer-stabilised earthen materials (2019)
Presentation / Conference Contribution
Muguda, S., Hughes, P., Augarde, C., Perlot, C., Bruno, A., & Gallipoli, D. (2019). Geotechnical characterisation of recycled biopolymer-stabilised earthen materials.

Earthen structures (i.e. structural units manufactured from soil) are often regarded as sustainable forms of construction due to their characteristically low carbon footprint. Unstabilised earthen materials can easily be recycled or disposed, however... Read More about Geotechnical characterisation of recycled biopolymer-stabilised earthen materials.
