Untersuchung zur Struktur und Porenraumverteilung von künstlich hergestelltem organischem Bodenmaterial

Organic soils present significant challenges in construction due to their low shear strength and high deformability. As construction on such soils becomes increasingly common, understanding their behavior is critical. However, field studies on natural organic soils are complicated by their high variability and inhomogeneity. This study addresses these challenges by investigating artifi-cially produced organic soil materials, created through the mixing of mineral and organic components.
The primary objective is to analyze the structure and pore distribution of the-se materials under varying organic content levels (e.g., 25%, 50%, 75%). The research encompasses a literature review of imaging techniques (e.g., microscopy) and mercury intrusion porosimetry, as well as their application to organic soils. A series of experiments are conducted, including classification tests (e.g., grain size distribution, Atterberg limits) on raw materials and mix-tures, along with the preparation of samples with differing organic contents for advanced analyses. Imaging techniques are employed to examine the microstructure, and mercury porosimetry is used to characterize the pore space distribution.
The findings are presented and compared with existing experimental data and literature. This research contributes to a better understanding of the be-havior of artificial organic soils, offering insights into the influence of prepara-tion methods and organic content on their structural and geotechnical proper-ties.
