This is a technical report about cement stabilization in general and the stabilization process during the construction of a warehouse in Halmstad, Sweden in particular and is written at the section for economy and technology at Halmstad University in collaboration with NCC Anläggning. NCC encountered variations in compression strength in the stabilized material on the first warehouse that they constructed for the company Biltema. In our report we used the stabilization process of the second warehouse for the same company as a reference to determine what could be done to get a more homogeneous result for future projects. We also looked in to what testing method is the most suitable to determine the result of the stabilization. After interviews with people involved in the process and visits on the work site we have come to the conclusion that the most probable cause to the variations in compression strength is segregation in the ballast material. This segregation can occur in several different occasions in the process such as during the production, transportation and handling on the work site. Other causes for the variation can be improper compaction, overlapping stabilization in some places and different duration of hardening of the samples that are tested. The best way to do in situ test of the stabilized material is to do seismic investigations as those are non-destructive tests in comparison to taking core samples and you can discover any cracks or air bubbles in the material.
