| Abstract | The aim of the tests was to determine the changes in the permeability coefficient of fly ash by adding 2, 5 and 10% of bentonite. Due to its internal structure, fly ash, can be serve as a sealing material. Simultaneously, its acquisition does not involve high costs. Therefore, the authors considered the possibility of combining it with a small addition of bentonite to produce a relatively inexpensive sealing material. During the tests, the permeability coefficient was marked using an oedometer with a variable hydraulic gradient on laboratory prepared tests samples at compaction index 0.95. As a result of carried out tests it was noted that even a small (2%) bentonite addition caused the reduction of a permeability coefficient by one order of magnitude, relative to starting value. At the addition of 10%, a reduction by two orders of magnitude of the afore-mentioned parameter was noted. From the point of view of “characteristic flow water” and “classification of permeability”, it can be concluded that the pure ash exhibits weak flow water characteristic and low permeability; the 2% addition of bentonite lowers the permeability of mixtures even further, while the addition of 10% renders this material virtually impermeable from the practical point of view. |
