Rammed earth is a technique of forming in-situ structural wall elements using rigid formwork. Advantages of rammed earth walls include flexibility in plan form, a scope for adjusting the strength and wall thickness, variety of textural finishes, lower embodied carbon and energy, etc.. The thesis deals with an extensive experimentation on sawdust ash stabilized rammed earth specimens. Two varieties of specimens (cylindrical, cubes) are to be used in the experiments. A natural soil and its reconstituted variants were used in the experimental work. Details of the experimental programme, characteristics of raw materials used in the experimental investigations, methods of preparing different types of specimens and their testing procedures are discussed in detail. The aim is to establish properties of locally available natural soil and comparing it with properties of soil suitable for rammed earth construction and effect of Sawdust ash (SDA) on properties of natural soil used for rammed earth.
