Earthen Concrete

This lecture discusses earthen concrete, a sustainable alternative to traditional cement concrete, where clay is used as a binder instead of cement. The advantages of earthen concrete include low energy consumption, ease of construction, thermal properties, fire resistance, and the ability to incorporate waste materials. Various stabilization techniques are explored, such as mechanical compression, reinforcement with fibers, hydrophobization, and physico-chemical stabilization. Different construction methods for earthen concrete are presented, including adobe bricks, rammed earth walls, and cob walls, each with its unique characteristics and applications.
