Determination of Mechanical Properties of Mountain Rocks in Piedmont Areas of Namangan Region

The article presents a detailed study of the physical and mechanical properties of natural mountain rocks that are commonly used by the local population as construction materials in the mountainous areas of Chartak District, located in the Namangan Region. The research was conducted to determine the suitability of these rock types for various construction and infrastructure purposes, especially in regions where natural resources are directly used from the surrounding environment. As part of the study, several critical parameters were analyzed through laboratory testing. The compressive strength of the examined rock samples was found to range between 66 and 78 MPa, which indicates a relatively high ability to withstand axial loads. This makes the rocks well-suited for use in load-bearing walls and foundations. In addition to compressive strength, the flexural strength of the rocks was assessed. The values ranged from 5.63 to 13.07 MPa, reflecting the materials’ capacity to resist bending forces, which is crucial in structural components subject to stress and vibration. These values suggest that the rocks exhibit sufficient resistance to flexural deformation, which further supports their application in various building elements. Another significant aspect evaluated was the abrasion resistance, represented by the index И₁, which ranged from 11.6% to 11.8%. This relatively low abrasion loss indicates that the rocks possess good wear resistance, making them particularly effective for use in areas exposed to friction and mechanical wear, such as pavements and road surfaces. Furthermore, when the obtained values were compared to relevant construction and materials standards, it was determined that these rocks meet the necessary requirements for use in the construction of highways, pedestrian walkways, and structures subjected to high loads. Their strength, durability, and resistance to external influences make them a viable option for sustainable and long-term use in civil engineering projects. Overall, the findings of this research provide valuable insight into the engineering characteristics of locally available rock materials and support their broader application in infrastructure development, especially in rural and mountainous regions where access to industrial materials may be limited.
