“…Complementary tests of fly ash, such as leachability of heavy metals, hydrogen ion content and determination of radioactivity, were carried out, as demonstrated in the earlier papers (Brzeziński 2020, Brzeziński & Iskra-Świercz 2021, Brzeziński et al 2023. They showed complete safety and harmlessness of this material for the natural environment.…”

“…The tests of the collected soil showed a high organic content of 62.9% (tested by thermogravimetric method), density of 9•10 2 kg/m 3 , moisture content of 350% and porosity of 0.70. The degree of decomposition on the Van Post scale was rated as H4-H5 (Post 1922), and the determined concentration of hydrogen ions was 6.5 (Brzeziński & Iskra 2016, Brzeziński 2017, Brzeziński 2020. Considering the performed test and macroscopic evaluation, the collected peat can be classified as fibrous peat, turning into pseudofibrous.…”

The paper presents the test results of the shear strength of composite materials, in which the base material was peat. The materials modifying the mineral part of the peat ground skeleton were fly ash and hydrated lime. The research was carried out for two groups. In group 1, the ratio of the mass of the peat skeleton to the mass of fly ash was equal to one, and in group 2, it was two. Hydrated lime content in the unit mass of the composite in group 1 was 2.4, 4.8 and 9.2%. In the second group, it was 1.6, 3.2 and 6.4%. The test results showed that the materials from group 1. (P/FA = 1) are characterised by the highest shear strength compared to materials from group 2. (P/FA = 2), regardless of the content of hydrated lime. It should also be noted that the shear strength of the materials of group 1 was significantly higher than the shear strength of the base material, which was peat.
