Abstract

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.

1. Introduction

Mountain rocks have been widely used as construction materials since ancient times. Due to their high strength, durability, and long service life, they remain significant in modern infrastructure projects. However, the physical-mechanical properties of rocks can vary considerably depending on their mineralogical composition, structure, and formation conditions. Therefore, it is essential to accurately evaluate their compressive strength, flexural strength, and abrasion resistance before using them as construction materials.

In recent years, numerous scientific studies have been conducted on the mechanical properties of rocks. Fjaer et al. (2021), in their comprehensive work "Petroleum Related Rock Mechanics", examined various aspects of rock behavior under stress, including compressive and tensile strength, elastic deformation, and failure mechanisms. Their research provided valuable insights into how different rock types respond to mechanical loads in subsurface environments.

[1]

. According to his research, the average compressive strength of granite ranges between 150-300 MPa, while that of limestone is 30-100 MPa. Zhang and Liu investigated rock compressive resistance using electron microscopy, revealing that when rock porosity exceeds 5%, strength sharply decreases

[2]

Gonzalez studied the flexural strength of metamorphic rocks such as marble and quartzite in accordance with GOST 8264-85, finding their flexural strength to be 10-20 MPa, which is lower than that of igneous rocks. Prikryl's research examined the effect of moisture on rock flexural properties, confirming that under 95% relative humidity, flexural resistance decreases by 15-20%

[3]

Kazi and Al-Mansour's studies demonstrated that rocks like basalt and diabase exhibit the highest abrasion resistance, with wear rates below 2%, while limestone is the weakest, with wear rates exceeding 10%. Aydin and Basu used the Micro-Deval method to analyze the influence of intergranular bonding strength on abrasion resistance.

[4]

In recent years, the use of rocks as construction materials has expanded significantly. Their unique strength, decorative properties, cost-effectiveness, and environmental benefits have secured them a key role in modern construction. In the foothills of Namangan Region, local communities widely use mountain rocks for building foundations, pavement slabs, and decorative elements

[5]

. However, a comprehensive evaluation of material properties—including compressive strength, flexural strength, and abrasion resistance—remains a pressing issue in construction practice.

The primary objective of this study is to investigate three key indicators—compressive strength, flexural strength, and abrasion resistance—of mountain rocks extracted from the Chartak District of Namangan Region (an area where local populations actively quarry these rocks). Based on the findings, the study aims to determine their optimal applications in construction.

When determining the compressive strength of natural stones, their operational efficiency in various conditions and environments is studied. Primarily, the advantages of using stones for walls and foundation parts in residential construction are established. Therefore, this research was conducted extensively under laboratory conditions.

Figure 2. Test specimens for bending.

The flexural strength of the investigated rock samples was determined in accordance with GOST 8462-85 and GOST 32730-2014 standards. The flexural test was carried out using the three-point bending method. A total of six rectangular prism-shaped samples with dimensions of 40×40×160 mm (a×b×h) were prepared in accordance with GOST 8269.0 The flexural strength was calculated using the following formula:

σ_{eg} = \frac{3 F_{\max} ∙ l}{2 b h^{2}}

The abrasion resistance test was conducted according to GOST 8269.097 (section 4.4.10). Although structurally similar to the Los Angeles test, this method determines the crushing outcome of stones through a 1.25 mm sieve. The proportion (%) of crushed fraction passing the sieve is evaluated as the abrasion coefficient. Basalt and granite samples from Chortoq district, Namangan region, showed abrasion coefficients below 25%, qualifying them as high-quality materials suitable for road construction. This methodology aligns with the construction standards of the Republic of Uzbekistan and is consistent with international practice.

The flexural strength of the investigated rock samples was determined in accordance with GOST 8462-85 and GOST 32730-2014 standards. The flexural test was carried out using the three-point bending method. A total of six rectangular prism-shaped samples with dimensions of 40×40×160 mm (a×b×h) were prepared in accordance with GOST 8269.0 (see Figure 2). The samples were collected from quarries located at a distance of 500 meters from each other. The span between the supports was set to

l = 2.5 a

, which corresponds to

l = 100

mm. A bending load was applied gradually to the center of the sample (Figure 2). When the applied bending force reached its maximum value, denoted as

F_{\max}

, the rock sample fractured.

Resistance to Abrasion Wear. The testing procedure involved 5000 grams of crushed stone within the 10-20 mm fraction, placed together with 11 steel balls weighing 400-500 grams in total, inside a rotating drum operating at 30-33 rotations per minute. The drum was rotated 500 times. After rotation, the sample was sieved through a 1.25 mm mesh, and the mass of fine particles passing through the sieve was weighed.

Figure 5. Dependence of rock compressive strength on sampling depth.

Figure 5. The results indicate a general increase in compressive strength with increasing extraction depth. Specifically, the compressive strength of the first sample taken from a depth of 2 meters was 67.26 MPa, while the eighth sample, extracted from 16 meters, exhibited a compressive strength of 78.26 MPa. This represents an increase of approximately 16.35% in strength with depth. The compressive strength values for each sample are as follows

[15]

Table 1. These results clearly show that the compressive strength of the rock tends to increase with depth. This trend may be attributed to higher rock density and improved crystalline structure in the deeper strata of the formation.

To assess the flexural strength of natural rock samples, a three-point bending test was conducted on six specimens extracted from various locations and depths. For each sample, the maximum applied force (

) and bending strength

Figure 6. Figure 7. Table 2. The test results indicate a clear decreasing trend in flexural strength with increasing depth. The highest bending strength, 13.07 MPa, was observed in Sample 1 taken from 5 meters depth at Site 1. In contrast, the lowest value, 5.63 MPa, was recorded for Sample 6 extracted from 15 meters at Site 3. This represents a reduction in strength by a factor of approximately 2.3.

The bending strength values for the samples are as follows:

4	2/5	11970	7.48
5	2/10	11358	7.10
6	3/15	9001	5.63

These results suggest that although rock hardness generally increases with depth, its resistance to bending tends to decline. This trend may be attributed to increased internal microcracking, structural discontinuities, or changes in mineral composition at greater depths.

[7, 8]

Such findings are essential for evaluating the flexural behavior, fracture susceptibility, and structural integrity of rock formations in geotechnical and engineering applications.

To evaluate the abrasion resistance of natural rock samples, laboratory tests were conducted to determine the wear index (

И

) under frictional forces

[9, 10]

. Based on the standard classification, abrasion quality is categorized as follows. Table 3.

According to the results:

Table 3. abrasion quality.

Experience sample High quality	Average quality $И 1 \leq 25 %$	Past quality $И 2$ =25-35%	Low quality $И 3$ > 35%
1	11,6	-	-
2	11.4	-	-

As both samples fall below the 25% threshold, they are classified as high-quality rocks with excellent resistance to abrasion.

These results indicate that the tested rock materials possess high durability, low susceptibility to wear, and long-term performance potential. Such characteristics make them highly suitable for use in construction applications exposed to constant frictional forces, including pavements, road surfaces, and structural stonework.

[11, 12]

5. Conclusions

Based on the conducted research, it can be concluded that the compressive strength of rock increases with greater depth. At a depth of 2 m, the destructive stress was 67.26 MPa, while at 16 m, it reached 78.26 MPa. Additionally, the difference in rock strength was 4.74 MPa in the 2-4 m depth range but only 0.45 MPa in the 14-16 m range, indicating a decrease in the variability of compressive resistance with depth.

The study results also revealed that flexural strength decreases with increasing excavation depth. Samples from upper layers (1/5 - σ_bend = 13.07 MPa) exhibited higher flexural strength compared to those from deeper layers (2/15 - σ_bend = 5.63 MPa). This confirms that the physico-mechanical properties of rocks vary with depth, and near-surface layers are mechanically more stable.

Furthermore, the average weathering resistance index (И1) of the studied rock samples was 11.5%, demonstrating high weathering resistance in the region's rocks.

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.},

AB  - 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.
