Editors have highlighted the following attributes while ensuring the content's credibility:A cardboard-confined rammed earth column and CFRP-confined rammed earth column. This innovative material, called cardboard-confined rammed earth, is composed entirely of cardboard, water and soil—making it reusable and recyclable. Image of study lead author Dr. Jiaming Ma holding the cardboard-confined rammed earth material. Ma said cardboard-confined rammed earth could be an effective solution for construction in remote areas, such as regional Australia, where red soils—ideal for rammed earth construction—are plentiful.
