A Study on Carbon-Neutral Biochar-Cementitious Composites
The global environmental challenges are calling for novel solutions and sustainable practices in the fields of architecture and construction. To respond to the SDGs agenda, the research investigates strategies for integrating biochar as an aggregate for carbon-neutral cementitious composites and to gain knowledge upon the effects that large quantities of biochar within the material system has on mechanical properties as well as carbon sequestration. The paper presents the development and assessment of a series of grades of Biochar Cementitious Mortars (BCMs). Assessment is structured upon (i) material consistency, (ii) structural performance and (iii) composite’s embodied carbon. The results propose that biochar, derived from agricultural waste, and as a carbon-sequestering material, can be used to lower the net embodied carbon of cementitious composites when used as an amendment and cement replacement. As BCMs meet compressive strength standards and can provide building materials with a net-negative embodied carbon, the material research provides valuable input for applications in the construction sector. It is proposed that in the later stages of the research the developed BCMs can be applied within a materially driven design process trough functionally grading the material and consequently designs with optimised environmental impact can be achieved.
