Pulled from the oven just right. Trustworthy, fact-dense, deeply satisfying.
Summary
RMIT researchers have developed an innovative building material that encases rammed earth in permanent cardboard formwork, eliminating the need for cement typically required in traditional rammed earth construction. This sustainable approach maintains the structural integrity of rammed earth while using cardboard as permanent formwork, potentially revolutionizing sustainable building practices by reducing cement usage and environmental impact.

· 2 pulledResearchers at the Royal Melbourne Institute of Technology in Australia have created a building material where rammed earth is encased in permanent cardboard formwork, eliminating the need for cement.
Typically, rammed earth walls are made by compacting layers of soil mixed with about 8 to 10 per cent cement inside temporary moulds designed to improve strength and durability.
