The technique of soil treatment is known for a long time, currently, during the big motorway programs this technique is experiencing important to reach zero imprints and zero deposit in a context of sustainable development or the socio-economic and environmental challenges incite during the work of earthworks. Our work puts highlights the treatment of fine soils in westerns region of Algeria (wilaya of Tlemcen, a project to construct a payment station for the entry of the wilaya (sample n°1), electrical post 400/200 KVA in the locality Ain Fetah (sample n°2)), belonging to the class A3h (very plastic clay) according to the Technical Guide for Earthworks (GTR), whose use in the raw state would involve great risks of stability because of their plasticity (Ip > 20%) and their low capacity (CBR < 25) according to the Specification of the Algerian Loads, Technical Clauses (CSDCA-CT) by the incorporation of the stabilizing agents, for example the variant of locally manufactured CEM II / A42.5N composite cement, in order to define their behaviours by examining the variation of their characteristics determined according to the Algerian standards and at a ambient temperature according to the additive dosage and to contribute to the deduction of the interest of the method demonstrated previously. The results obtained clearly show a tendency the rearrange classification of the soils studied according to the unified system en proportion whit to the additive dosage (0 to 14%) in view of the appreciable change in the plasticity behaviour, which results in a decrease in the plasticity index, going up to 37.7% and the 11% of the maximum dry density accompanied by a satisfactory increase in the suitability of the materials to be supported a load with different moisture content and changes in water regime exceeds 100%. Given the unavailability of other exploitable deposits near the site and the experimental results obtained, the variant of the treatment seems feasible.

Subject. The article discusses the sustainability of regional economy development, its definition, and the substance of sustainable development. Objectives. We aim at performing a comprehensive analysis of indicators of sustainability and adaptability of regional development in the context of digitalization, formulating a strategy for economic behavior that takes into account the multidimensional nature of regional inequality and is focused on boosting the economic potential of regions. Methods. The study draws on dialectic and systems approaches, general scientific methods of retrospective, situational, economic and statistical, and comparative analysis. Results. The sustainability of the region focuses on improving the human welfare over long time horizon. This happens in three areas, i.e. maximizing the efficiency of resource use; ensuring justice and democracy; minimizing resource consumption and environmental damage. The stability of the region can be assessed by using one parameter, or by combining the parameters in accordance with the type of region and expected results. Conclusions. The adaptation of a region to changing conditions depends on its type (‘adapted’, ‘adaptive’, and ‘non-adapted’). Regional inequality has two main components: difference in economic potential and social satisfaction of residents. Another component, affecting the stability and adaptability of regions, is the level of their digitalization. However, some regions have only formally embarked on the path of digitalization. Moreover, a focus on smart technologies, solutions and digitalization often leads to ignoring the goals of sustainable development. Smart technologies should be aimed at ensuring sustainability within the framework of the smart sustainable city concept.

The abandonment of renovation works is an extremely important factor causing degradation of the building. Omission of repairs may lead to a threat to the stability of the building’s structure, threaten the lives of users, further damage to the building by damaging further elements. The aim of this article is to analyze the consequences of abandoning renovation works in order to minimize the occurrence of construction failures in the future. The article presents problems related to the abandonment of repair works of damaged elements. A classification of the effects of abandonment of repairs for historic buildings has been worked out. Industrial heritage buildings were often not used for a long time, and the lack of maintenance very often caused their partial or even complete destruction. The progressive degradation of buildings is mainly the result of human negligence, lack of effective, and continuous maintenance. The problem of abandonment of repairs is presented on the example of the granary in Krosno Odrzańskie.

The article discusses the indicators of sustainable development given from the standpoint of the classical concept of sustainable development. The methods used are analyzed to identify criteria for sustainable development. The indicators of sustainable development have been known and developed for a long time. However, their development did not take into account the regional fix, which would allow creating a permanent set of the most representative indicators for a certain territory. Volgograd and Rostov agglomerations are chosen as objects. A complex analysis of the regional indicators of sustainable development is carried out taking into account physiographic, climatic, sectoral features, the economic potential and ecological well-being of Volgograd and Rostov agglomerations. The work assesses the ecological and economic sustainability of the agglomerations under study, which allows to give the comparative analysis of the territory development predictive models. Today, it is still too early to talk about the effectiveness of achieving criteria for sustainable development in urban agglomerations. The accepted methods cannot be considered effective due to the fact that the efforts of all areas of management are needed. In the forecast, we can talk about a slight increase in the stability of Rostov agglomeration due to capital inflows. Taking into account current trends, Volgograd agglomeration can face a gradual decrease in sustainability requiring an immediate intervention.

Cost Of Construction

Kuttanad clays are low strength, soft, organic clay deposits found in the Kuttanad areas of the Alappuzha district, Kerala. Lots of failures have been reported to the structures built over it due to its swelling - shrinking characteristics. To enhance the load-bearing capacity and decrease the settlement characteristics, the addition of appropriate stabilizing agents is considered the most efficient technique in soil stabilization applications. Soil stabilization techniques using traditional stabilizers in mass projects have become costly due to the increase in the cost of materials like cement, lime, fly ash, etc. Moreover, cement production also accounts for global warming due to the emission of carbon gas. Hence studies are going on regarding the effectiveness of using non-traditional materials that can react faster as stabilizing agents and thus reducing the cost of construction. This paper focuses on studying the suitability of a non-traditional nanotechnology-based organo-silane compound in the treatment of Kuttanad clay soils. Observations were made for the variation in the strength characteristics of the soil such as maximum dry density, optimum moisture content, Unconfined Compressive Strength (UCS), California Bearing Ratio (CBR) strength of samples stabilized with varying dosages of nanochemical for curing periods up to 28days.

Subject. The article discusses Russia’s economy and analyzes its effectiveness. Objectives. The study attempts to determine to what extent Russia’s economy is effective. Methods. The study is based on the systems approach and the statistical analysis. Results. I discovered significant fluctuations of the structural balance due to changing growth rates of the total gross national debt denominated in the national currency, and the stability of growth rates of governmental revenue. Changes in the RUB exchange rate and an additional growth in GDP are the main stabilizers of the structural balance, as they depend on hydrocarbon export. As a result of the analysis of cash flows, I found that the exports slowed down. Financial resources are strongly centralized, since Moscow and the Moscow Oblast are incrementing their share in the export of mineral resources, oil and refining products and import of electrical machines and equipment. Conclusions and Relevance. The fact that the Russian economy has been effectively organized is proved with the centralization of the economic power and the limits through the cross-regional corporation, such as Moscow and the Moscow Oblast, which is resilient to any regional difficulties ensuring the economic growth and sustainable development. The findings would be valuable for the political and economic community to outline and substantiate actions to keep rates of the economic growth and sustainable development of the Russian economy.

There are many types of coasts classifications that indicate main coastal features. As a rule, the "static" state of the coasts is considered regardless of their evolutionary features and ways to further transformation. Since the most part of the coastal zone studies aimed at ensuring of economic activity, it is clear that the classification of coast types should indicate total information required by the users. Accordingly, the coast classification should include the criterion, characterizing as dynamic features of the coast and the conditions and opportunities of economic activity. The coast classification, of course, should be based on geomorphological coast typification. Similar typification has been developed by leading scientists from Russia and can be used with minimal modifications. The authors propose to add to basic information (geomorphological type of coast) the evaluative part for each coast sector. It will include the estimation of the coast changes probability and the complexity of the coast stabilization for economic activity. This method will allow to assess the dynamics of specific coastal sections and the processes intensity and, as a result – the stability of the coastal area.
