Short-term electrical conductivity and strength development of lime kiln dust modified soils / Renpeng Chen in Journal of geotechnical and geoenvironmental engineering, Vol. 135 N° 4 (Avril 2009)  

Public ISBD [article]  inJournal of geotechnical and geoenvironmental engineering > Vol. 135 N° 4 (Avril 2009) . - pp. 590–594 Titre : Short-term electrical conductivity and strength development of lime kiln dust modified soils Type de document : texte imprimé Auteurs : Renpeng Chen, Auteur ; Vincent P. Drnevich, Auteur ; Radha Krishna Daita, Auteur Année de publication : 2009 Article en page(s) : pp. 590–594 Note générale : Geotechnical and geoenvironmental engineering Langues : Anglais (eng) Mots-clés : Dust Electrical conductivity Penetration resistance Clays Résumé : Lime kiln dust (LKD) is used for modifying pavement subgrades to expedite construction on wet clayey soils. This paper describes the short-term development (typically, over the first 3to7days ) of electrical conductivity and penetration resistance of LKD-modified soils. The normalized net change of electrical conductivity is solely related to the LKD dosage. The decrease of electrical conductivity with time coincides with the increase of penetration resistance with time. The correlations of electrical conductivity with strength gain in LKD and lime-modified soils suggest that electrical conductivity measurements can potentially be useful for quality control in field applications.
