| In today's fast-paced practice, we encounter non-compliance with the standard "STN EN ISO 22475-1 Geotechnical investigation and testing. Sampling methods and groundwater measurements. Part 1: Technical principles". This standard includes principles for sampling and handling soil samples. The principles of sample handling are often violated, the strength states of samples are not maintained, and it is common for such samples to arrive at the geotechnical laboratory in a disturbed state. Then it becomes difficult to conduct a comprehensive investigation of the deformation or strength properties of soils on the given sample. Therefore, the project will focus on determining the deformation and strength properties of fine-grained soils on reconstituted samples and their comparison with naturally deposited soil samples. Reconstituted soils are soils whose moisture is adjusted to the liquid limit wL (optimal moisture wL<w<1.5wL) and which have been consolidated, preferably under one-dimensional conditions (Burland, 1990). By adding water to the soil and mixing them, we create a homogeneous mass, and by consolidation, we remove excess air bubbles. |
