Effect of water on the rheological properties of typical chernozem in Kursk oblast

详细

The rheological properties of typical chernozem were investigated by the amplitude sweep test on an MCR-302 rheometer (Anton Paar, Austria) for three water contents: maximum swelling, the liquid limit, and capillary rupture. A method is proposed for determining the water content of capillary rupture on an analyzer by using the curves for soil drying at constant temperature, determined simultaneously with the water content. Comparison of rheological soil characteristics at different soil humidity has shown that variations in the forms of soil water cause changes in the rheological soil behavior from viscous to elastic–brittle.
