Badania wodoprzepuszczalności gruntów spoistych na podstawie metody Kaczyńskiego

Theoretical and practical assumptions of Kaczyński method for laboratory determination of filtration coefficient in compact ground described in the paper. Tests focused on determining technical-methodic conditions of measurements for establishing the influence of chemistry of the filtrating water on the obtained parameters. The physical model of compact ground as well as physicochemical properties of various concentrations of NaCl and CaCl2 water solutions used as working fluids were analyzed quantitative and qualitative. For comparison's sake, tests for demineralized water were made. The obtained results are promising as far as evaluation of the correction coefficient accounting for the influence of chemistry of water on water permeability of ground is concerned.
