Abstract [sv]

Som en förstudie inom Svensk Djupstabilisering har orienterande undersökningar utförts om kalktypens inverkan på stabiliseringseffekten i olika leror. Undersökningarna, som utförts i laboratorium, har omfattat provning av åtta olika typer av kalk i två olika leror. Förstudien visar att typen av kalk som används kan ha stor betydelse för stabiliseringsresultatet även då skillnaderna i egenskaper som bränningsgrad, kornstorlek, CaO-halt m.m. är relativt små. Sju av kalktyperna kom från olika platser i Sverige och en kalk kom från Polen. De svenska kalktyperna kom från Köping, Rättvik, Boda och Landskrona. Kalktyperna var av varierande grovlek och bränningsgrad. Utförda analyser av olika egenskaper hos kalken visade inte på några större skillnader mellan de olika kalktyperna. En av kalktyperna särskilde sig något från övriga och uppvisade sämre reaktivitet. Denna kalk hade hanterats annorlunda än övriga kalktyper före provningarna i denna studie.

Abstract [en]

Preliminary investigations of the influence of the type of quicklime on stabilisation results have been conducted as a pilot study by Svensk Djupstabilisering (the Swedish Deep Stabilisation Research Centre). The investigations were performed in the laboratory and comprised tests on eight types of lime in two different clays. The pilot study shows that the type of lime used can be of major importance for the stabilisation result even when the differences in properties such as degree of calcination, grain size, CaO content, etc. are relatively small. Seven types of lime were obtained from different locations in Sweden and one type from Poland. The Swedish types came from Köping, Rättvik, Boda and Landskrona. They were of varying coarseness and degree of calcination. Analysis of various properties of the lime did not reveal any significant differences between them. One of the types of lime showed somewhat poorer reactivity than the others. This lime had been handled in a different way compared to the other types prior to the tests in this study.
