Description:

The paper presents the test results of a bentonite and sand mixture as a mineral material used for spot seals of low flood embankments in the area of Żuławy Elbląskie. The test results showed very good properties of the mixture, i.e., good compaction, a low filtration coefficient, and significantly higher shear strength compared to the construction material of the flood embankment in Nowe Dolne. The obtained water permeability values of 10-8 m/s are characteristic of very low permeable soils. The strength parameters of the mixture are φ = 34.8o and cohesion c = 72.69 kPa. It should also be noted that the shear strength of the B/Sa mixture is significantly higher compared to the shear strength of the construction material of the flood embankment in Nowe Dolno.
