Towards poured earth construction mimicking cement solidification: demonstration of feasibility via a biosourced polymer
https://orcid.org/0000-0001-6259-894X
Abstract The feasibility of building with earth in the same and simple way as cement-based concrete has been demonstrated as an environmental-friendly alternative. Sodium alginate, a bio-sourced polymer, is used to induce a liquid–solid transition to a clay based suspension, similar to hydraulic binders. The polymer gelation occurs via calcium ions released from the binding phase through a gentle acidification of the mix. It leads to a substantial solidification of the wet material, theoretically sufficient to remove the formwork of an earth wall within 24 h without waiting for drying. Working time is adjusted using a chelator which forms complexes with calcium ions.
