Effect of Keratin Fibers on Setting and Hydration Characteristics of Portland Cement

Abstract

© 2019, © 2019 Taylor & Francis. The study investigated the effect of keratin fibers from waste chicken feather on the hydration characteristics of Type I Portland cement. The effect of varying amount of fibers on cement setting time, thermal and spectroscopic characteristics was investigated. Cement mix containing keratin fibers up to 6% by mass of cement showed increased initial and final setting times by 46% and 54%, respectively, compared to unmodified control samples. Thermal and infrared spectroscopic analyses suggest that keratin fibers possibly blocked hydrations sites or prevented cement crystallization which retarded cement curing.
