A Termite‐Inspired Alternative to Cement
Advanced Functional Materials, Volume 36, Issue 27, 2 April 2026.A termite‐inspired composite of clay, cellulose, and lignin forms a dense fibrous network with concrete‐like strength (32 MPa) and superior elasticity, processed at ambient temperature. Abstract Clay combined with organic materials is used by termites as a strong and durable construction material for their mounds with minimal environmental impact. Here,
