Dear AD

 

That is really interesting. So it can render a profound change in
characteristics.

 

Has the dung-water+clay chemisty been heard of in your area? It is a labour
only alternative to concrete.

Dear Crispin,

the natural soil in this part of India is black in colour (it is called
vertisol). It is extremely clayey. It swells when wet and contracts when it
dries, producing cracks in the process. So, it is absolutely useless for any
kind of construction. Our region was colonised about 2500 years ago. The
soil in old human settlements shows a distinctly whitish colour. It does not
expand when wet and does not crack on drying. This soil is prefered for any
kind of construction work. People kept their cattle penned next to their
houses. Archaeologists tell us that the vertisol gets converted into the
whitish soil due to the chronic mixing with animal dung
Yours
