INBLANDNING AV OLJEGRUS VID CEMENTSTABILISERING: EN LABORATORIEUNDERSOEKNING (MIXING IN 'OIL GRAVEL' WHEN STABILIZING CEMENT: A LABORATORY INVESTIGATION)
The practical significance of the effect of 'oil gravel' cannot be demonstrated by an investigation as small as this one, and it is limited to the material which was investigated. However, if one makes the same demands as to strength when 'oil gravel' is mixed in as when stabilizing cement without it, compensation can very probably be accomplished by increasing the amount of cement which is added. How large that addition needs to be was investigated in this case by a supplementary testing of samples with a higher admixture of cement. The results show that with a 10 percent 'oil gravel' content an admixture of about 10 percent more cement was needed to obtain a strength of 5 MPa for 7 days, which is a usual strength requirement in preliminary testing before cement stabilization. When the 'oil gravel' admixture was 25 percent, the amount of cement required to obtain the same strength increased by 50 percent. In the former case, the quota of cement required increased from 4.8 to 5.3 percent by weight and in the latter case it increased from 4.8 to 7.4 percent by weight.
