The question was posed to me in an online interview.

I want to ask this question from Types of Construction and Specification topic in section Village Housing of Civil Engineering Drawing

Answer 1

The correct option is (d) soil, janta emulsion and cowdung

The best I can explain: Soil – soil should not be too much clayey nor too much sandy (50% clay and 50% sand are suitable). Weight of dry earth should do about 112 kg per cu m (70 lbs per cu ft).

Bhusa – About 60% of bhusa by weight of dry soil is to be mixed.

Cowdung – It should be used for surface finishing.

Janta Emulsion – 5% of janta emulsion by weight of dry soil is to be mixed.
