With its potential for low embodied carbon, bio-stabilised earth offers a sustainable alternative to traditional carbon-intensive building materials. Moreover, unlike lime and cement stabilisation, bio-stabilisation methods hold the promise to improve the durability of earthen materials while retaining their moisture buffering capacity and recyclability. Despite the promising characteristics of bio-stabilised earth, research on the topic remains limited. The RILEM TC BEC aims to address this gap by advancing the understanding of bio-stabilisation. Its objectives include developing a classification system for bio-stabilisation techniques, examining their effects on the microstructure and chemical composition of earthen materials, and evaluating their macroscopic impact on mechanical and hygrothermal properties. The TC also aims to develop and promote a performance-based design approach for diverse applications of bio-stabilised earthen materials. Finally, the TC intends to evaluate the role of bio-stabilised earth constructions in climate change adaptation and mitigation strategies. This paper introduces the work of the RILEM TC BEC and presents findings from its literature review, focusing on the potential of bio-stabilised earth for climate change adaptation and mitigation.

摘要

With its potential for low embodied carbon, bio-stabilised earth offers a sustainable alternative to traditional carbon-intensive building materials. Moreover, unlike lime and cement stabilisation, bio-stabilisation methods hold the promise to improve the durability of earthen materials while retaining their moisture buffering capacity and recyclability. Despite the promising characteristics of bio-stabilised earth, research on the topic remains limited. The RILEM TC BEC aims to address this gap by advancing the understanding of bio-stabilisation. Its objectives include developing a classification system for bio-stabilisation techniques, examining their effects on the microstructure and chemical composition of earthen materials, and evaluating their macroscopic impact on mechanical and hygrothermal properties. The TC also aims to develop and promote a performance-based design approach for diverse applications of bio-stabilised earthen materials. Finally, the TC intends to evaluate the role of bio-stabilised earth constructions in climate change adaptation and mitigation strategies. This paper introduces the work of the RILEM TC BEC and presents findings from its literature review, focusing on the potential of bio-stabilised earth for climate change adaptation and mitigation.
