Bentonite granulates as a seals for mobile flood barriers
Bentonites and other smectite raw materials are widely used in many industries. The authors of the study analyzed the suitability of swelling granulates for their use as a seals in mobile flood barriers. For this purpose, a comparative analysis of the swelling and granulation parameters of three samples available on the market was performed. This results was compared with a macroscopic swelling test, which was realized on the specially prepared test stand. The carried out research shows that not only the content of the swelling minerals – mainly smectite – affect on the sealing of the system, but also they are determine by granules size distribution and the type of smectite.
