The paper discusses results of mechanical and technological tests of soil-cement composites made with cohesive or non-cohesive soil.The compositions of the soil-cement mixtures analysed differed in terms of their cement paste volume fractions and water-cement ratios.Limiting values of these technological parameters that enable the application of the soil-cement mixtures obtained in real life conditions for the purposes of the Deep Soil Mixing(DSM)method were determined.Based on the test results obtained,it was found that mechanical properties of the materials analysed were very sensitive to changes in their compositions.Variations in the volume fraction of cement paste within the range analysed caused mechanical properties to change even by an order of magnitude.
