| Summary: |
The study of engineered expansive soils attracts the attention of
researchers since this soil is mixed and increasingly used in many geotechnical
and geoenvironmental application. This paper attempts to the study of swelling
properties i.e. swell and swelling pressure, rate of swell, and water adsorption
during swell. The kaolin-bentonite mix and sand-bentonite mix specimens are
statically compacted and tested in conventional oedometer apparatus for swelling
determination. The results of the study show that the mechanism of swell follows
three distinct stages: intervoid, primary, and secondary swelling. The swell occurs
since the soils adsorb water during water uptake. The rate of swell and maximum
swelling are successfully determined using hyperbolic equation |
