Abstract EN
Chicken feathers are composed mainly of avian keratin, a fibrillar protein with a complex structure, and important properties such as durability, hydrophobicity, being chemically unreactive, and depending on the specific function can change its morphological and inner structure.
This study takes advantage of these features and for the first time the use of keratin from chicken feathers to modify characteristics on expansive soils is reported.
Swelling characteristics of remolded expansive soil specimens were studied through varying the percentage of keratin fiber content using 0.25, 0.50, 1.00 and 3.00 wt%.
One-dimensional swell-consolidation tests were conducted on oedometric specimens, specific surface area was determined using methylene blue, and degree of saturation was also analyzed.
Finally random distribution and interaction between keratin structures and soil were studied by scanning electron microscopy.
The results show that randomly distributed fibers are useful in restraining the swelling tendency of expansive soils.
The maximum reduction of pressure (43.99%) due to swelling is achieved by reducing the void ratio, which can be reached with the addition of chicken feather keratin structures to the expansive soil.
Finally, the mechanism by which discrete and randomly distributed fibers reduce swelling pressure of expansive soil is explained.
