Long-term properties of lime-cement treated clay

Abstract

In this paper, some results from an on-going project regarding long-term properties of in situ lime-cement stabilized columns of clay, are presented. In the field, core sampling and pillar sounding were performed on 30 years old columns at the test site Håby in Sweden. In the laboratory, strength tests and accelerated leaching tests on the core samples were conducted. For the leaching tests and the strength tests respectively, newly developed equipment was used. The results show a possible strength increase with time and the new equipment seem to work well.
