Influence of Active Surface Materials for Shear Strength of Clay Soil Pavir iaus aktyvi j med iag taka molini grunt kerpamajam stipriui

The article deals with the active surface materials (ASM) on the clay soil shear strength parameters, which are used in calculating the building base strength and stability of soil pressure in to supporting surface and slope stability. From the known mineral composition of clay soil was partially removed calcium compounds and were polluted of different concentration of pollutants and the values were compared. The analysis of active surface material substance influence on clay soil shows that higher concetration of pollutants in solution results in decreased soil cohesion, where the angle of internal friction remains various values.
