Construction Sands in Kyiv Oblast
Kyiv Oblast, located in the central part of Ukraine, is renowned for its natural resources. One of the most important resources is construction sand, which is used in building construction, infrastructure projects, and other industries. Kyiv Oblast has a significant number of deposits of construction sand scattered throughout its territory. One of the most well-known deposits is located in the vicinity of Kyiv and Novoukrainka. Other significant deposits can be found near Vyshhorod, Fastiv, Brovary, and other cities and villages in the region.
The construction sand deposits in Kyiv Oblast have significant economic potential. Their extraction and further processing create jobs and contribute to the development of the construction industry in the region. Construction sand from the deposits in Kyiv Oblast is widely used in the construction sector for various purposes. It is an essential component in the production of concrete, bricks, plaster, and other building materials. It is also used for creating foundations, road surfaces, trench backfill, and other construction works.
Construction sand from the deposits in Kyiv Oblast has high quality and meets the standards of the construction industry, specifically DSTU B V.2 7–32–95. It possesses the necessary physical and mechanical properties as well as chemical composition, making it an ideal material for construction purposes. The evaluation of sand for concrete production involves several key factors. These include the grain composition of the sand, the presence of harmful impurities, and the content of dusty and clayey particles. Fine aggregate for concrete typically utilizes sand with a fineness modulus ranging from 1.5 to 2.5. Depending on the intended use of the concrete, the sand may have a clay content of less than 0.05 mm ranging from 2.0 to 3.0%, including clay lumps within the range of 0.25 to 0.5%. The sand may also contain particles smaller than 0.16 mm up to 15.0%, and for very fine sands, up to 20%.
Among the harmful impurities that may be present in concrete sands, organic residues, clayey and dusty particles, mica, sulfur and sulfuric compounds, and amorphous forms of silica are worth noting. The use of sand with a fineness modulus of 1.0–1.5 or 3.25–4.0 requires additional analysis based on technological tests and techno-economic justification to determine its suitability.
The suitability of sand for the production of silicate concrete, silicate bricks, and autoclaved silicate products is evaluated according to the requirements of DSTU B V.2.7–80, which pertain to grain composition, content of free quartz (SiO2), chemical composition, clay particle content, as well as harmful and organic impurities. No specific requirements are imposed on the grain composition of sands for the production of lightweight concrete and sand as a binding component for obtaining dense silicate concrete.
Among the clastic rocks in the territory of Kyiv Oblast, the most valuable for construction purposes are Quaternary alluvial sands. Minimal stripping work is required for their extraction as they are present directly on the surface over significant areas. These sands contain 90–98% quartz and have the lowest amount of impurities. Their thickness averages 5–10 meters, sometimes reaching 17–25 meters. Extraction primarily focuses on coarser-grained sands of river and near-river facies, with the productive thickness being controlled by their boundaries.
The widespread use of sands in various sectors of the construction industry for the development of Kyiv city and the region has led to numerous geological surveys for this valuable mineral resource. The first large-scale prospecting and exploration works for the deposits of construction sands in the Dnipro River were carried out from 1975 to 1977 by the Right-Bank Geological Expedition upon the request of Kyivmiskbud. Twenty sites were investigated, including 15 located in the course of the Dnipro River. In total, over 30 deposits of construction sands have been explored within the territory of Kyiv Oblast, and some of them are currently under development:
The Dnipro sand deposit is located within the course of the Dnipro River, from the mouth of the Desna River to the Vyshenky port. The valuable mineral is modern alluvial river sand, finely-grained and quartz-based. It is extracted using hydromechanical methods with transportation by barges. This sand is suitable for all types of construction work, and its quantity is practically unlimited.
The Stuhniv sand deposit is situated 7 km north of the town of Obukhiv, on the floodplain terrace of the Stuhna River. The valuable mineral is alluvial quartz sand, fine-grained. Its thickness ranges from 9.8 to 18.0 meters. It is used for the production of silicate bricks. There is a potential for reserve growth through the utilization of available areas in all directions.
The Zastuhniv sand deposit is located 2 km southwest of the town of Vasylkiv, on the second supra-floodplain terrace of the Stuhna River. The valuable mineral is fine-grained alluvial quartz sand. Its thickness is 8 meters. It is used for road construction.
The Pukhiv sand deposit is situated in the western outskirts of the village of Pukhivka, on the floodplain of the Desna River. The valuable mineral is fine-grained alluvial quartz sand, with water content at depths ranging from 0.1 to 2.1 meters. The sand thickness reaches up to 21.5 meters.
The Rozhiv sand deposit is located 0.3 km northwest of the village of Rozhivka, on the second supra-floodplain terrace of the Desna River. The valuable mineral is alluvial quartz sand, fine-grained. The average sand thickness is 28.0 meters, while the thickness of overburden rocks is 0.1 meter.
The Horenka sand deposit is situated near the village of Horenka in the valley of the right tributary of the Irpin River. The valuable mineral is very fine-grained alluvial quartz sand. The average sand thickness is 5 meters, and the average overburden rock thickness is 0.2 meter.

The extraction process of river sands is an important component of the construction and mining industries. River sands, also known as fluvial sands, are sedimentary materials formed as a result of river flow and erosion within river channels or streams. The extraction process involves the following stages:
1. Prior to commencing extraction, detailed exploration of the river sand deposit is conducted. This includes geological surveys, measurement of the thickness and dimensions of the sand layer, assessment of sand quality, and other investigations.
2. After exploration, a mining plan is developed. It involves determining optimal extraction locations, estimating the sand volume, outlining the technological processes, and managing the extraction operations.
3. Excavation can be carried out using multi-layer excavators, earthmoving machinery, or specialized floating vessels. The sand is collected from the riverbed and loaded onto dedicated transport vehicles for further transportation.
4. After excavation, the sand is transported to a processing facility, which can be a specialized treatment plant or factory.
5. Upon arrival at the processing site, the sand undergoes washing and sorting processes. The sand is washed and goes through a sorting process, where it is separated into different fractions according to industry and customer requirements.
6. After washing and sorting, the sand is ready for transportation to customers.
In summary, the construction sand deposits in the Kyiv region are invaluable resources with significant economic and infrastructure potential. Proper management of these deposits, ensuring sustainable development, and preserving natural resources are key tasks for maximizing the benefits derived from their utilization.
