    Abstract

    According to Dutch law the contaminated soil needs to be remediated or immobilised. The main focus in this article is the design of concrete blocks, containing contaminated soil, that are suitable for large production, financial feasible and meets all technical and environmental requirements. In order to make the design decision on the binder composition, binder demand andwater demand needed to be made. These decisions depend on the contaminations present and their concentration. Two binder combinations were examined, namely slag cement with quicklime and slag cement with hemi-hydrate. The mixes with hemi-hydrate proved to be better for the immobilization of humus rich soils, having a good early strength development. Based on the present research, a concrete mix with a binder combination of 90% blast furnace cement and 10% hemihydrate, a binder-content of 305 kg/m3 and water-binder factor of 0.667 gave the best results.
