A tin can wall is made from concrete and repurposed aluminium cans acting as an aggregate. The wall is later covered with stucco.

Concrete is a build material made from cement, sand, gravel or other types of aggregate, and water. The ratios vary depending on the type of concrete needed. Concrete is the most widely used man-made material in existence and second only to water as the most-consumed resource on the planet.[1]

Aircrete is an alternative to concrete.

Concrete buildings can be made using insulated concrete forms and concrete masonry units.
