Körnungskartierung

Körnungskartierung refers to the process of mapping the grain size distribution of a material. This technique is widely used in various fields, including geology, soil science, civil engineering, and materials science. The primary objective of Körnungskartierung is to understand and visualize how the sizes of individual particles are distributed within a larger sample. This information is crucial for predicting the material's properties and behavior.

In geology and soil science, Körnungskartierung helps classify soil types, such as sand, silt, and clay, and understand their agricultural or engineering suitability. Different grain size distributions influence properties like permeability, porosity, and shear strength. In civil engineering, it is vital for designing foundations, roads, and other structures, as the behavior of construction materials like concrete and asphalt is heavily dependent on their aggregate size.

The process typically involves collecting a representative sample, separating the particles by size using sieves or other methods, and then analyzing the proportions of each size fraction. The results are often presented graphically, such as in a cumulative frequency curve or a ternary diagram, which clearly illustrates the grain size distribution. This visualization allows for easy comparison between different samples and helps in making informed decisions regarding material selection and application. Körnungskartierung is a fundamental tool for characterizing granular materials.
