Compression Behavior of Rubber–Bentonite Mixture under Different Salinities

This study investigated the engineering properties of a rubber–bentonite mixture under different salt solution concentrations, mass ratios, and consolidation pressures. In addition, effects solute ion concentrations on compression index samples were compared. The results showed that coefficient could be reduced effectively by increasing weight percentage rubber without being affected solution. However, with increase in concentration, mixed materials ratios increased, when concentration exceeded 0.5 mol/L, increased more obviously. 0.1 mol/L NaCl solution, addition levels modulus material reduce ratio material. an environment low adding into enhance its compressive deformation resistance. content 50%, significant pores appeared sample, effect high intensified. also had swelling soil, degradation mechanical properties. emphasizes need to consider stability resistance saline–alkali areas erosion.
