Abstract

Building with unfired earth (mud) is an ancient practice that is regaining popularity due to the rising concern about the impact of the construction sector on climate. However, the low image of earthen materials is a major barrier to its acceptance in India, and is caused due to its poor water resistance performance. This research focuses on developing a low-cost, water resistant and desirable earthen building material for rural housing in India. This thesis contributes toward a better understanding of water ingress and water resistance in unstabilised and biologically stabilised earthen materials, especially cow-dung stabilised earthen blocks. Moreover, it addresses the three key aspects identified for rural earthen housing in India; 1. Affordability, by using inexpensive techniques and binder; 2. Durability, by enhancing the water resistance in both unstabilised and cow-dung stabilised earthen material, and 3. Desirability, by producing Compressed Earth Blocks of a good finish and aesthetic and using a widely acceptable stabiliser. The research work is expected not only to provide scientific insights that facilitate understanding and adoption of earthen materials but also the knowledge that can be directly applied in the construction of earthen houses.

Descriptive scope: 3 PCT

N.B. Descriptive scope is a count of how many of the five facets of empirical research are indicated by the words used in title, abstract and keywords. It is not intended as a judgement on the research; merely a count of the kind of word we would expect to indicate Phenomenon, Concepts, Theoretical framing, Empirical techniques, Analytical techniques. If all five are present, then a code of “5 PCTEA” will indicate this. If you feel the coding for this record is questionable, we welcome discussion around the terms we matched or the way we categorized them. The facet you would expect may not be coded, or a facet may be coded inappropriately. This can also bear on a larger question, of which facets should be treated as defining in construction management research. Please get in touch, and we will look at it. More details here
