  The use of gypsum-containing binders significantly expands both the raw material base and the possibilities of application of materials based on them. Clay-gypsum belongs to this group of binders. Clay-gypsum raw material and binder on its basis are local building materials. Binders based on clay gypsum have advantages under the following conditions: the remoteness of deposits of natural gypsum raw materials and the proximity of production from consumers. Clay gypsum is a natural formation of fine-grained crystalline gypsum, evenly mixed with clay or loam. The amount of gypsum varies from 50 to 95%. The aim of the research was the formation of scientific bases for obtaining clay-gypsum binder stabilized by its properties, as well as the development of optimized parameters for the production of this binder. As a result of research, the technological parameters of receiving clay-no-gypsum binder and modes of its thermal processing (firing) are optimized, and also the influence of technologies on the properties of clay-no-gypsum binder, which can be considered an analogue of binder received from natural gypsum raw material, is studied. It is established that at the age of 28 days of hardening, the compressive strength of clay-gypsum binder fired at the temperature of 250 oC reached 8.8–8.6 MPa, which at the accepted level of security allowed to obtain a binder of G-8 grade. The formation of soluble anhydrite did not exceed 1.5%.

  Evaluating the Economic Sustainability of Two Selected Urban Centers—A Focus on Amherst and Braintree, MA, USA

  While the topic of sustainable development has been extensively explored, there is a lack of quantitative assessment of economic sustainability in the scientific literature; moreover, the term is often interpreted with excessive attention to the environment but not socio-economic inequality. In addition, university cities are often considered the most sustainable, although the higher education system in the United States is often criticized for the inequality of access to it among different racial and other groups of the population. This paper adds to the debate about how the concepts of sustainability and economic development relate. Many researchers have noted that they come into conflict with each other because their ultimate goals are fundamentally different: a voluntary limitation of production and consumption in the interests of future generations and, conversely, the pursuit of well-being during our lives. We would like to explore the issue of economic sustainability, which, at first glance, may become a compromise between the two approaches outlined above. So, our study is devoted to exploring the ambiguous concept of economic sustainability, which can add some new knowledge to the understanding of how social, economic, and ecological factors relate to each other in the broader framework of sustainability. For this objective, we analyzed the economic sustainability of the town of Amherst, MA. The city’s top employer and core enterprise is the University of Massachusetts Amherst, with over 32,000 students and almost 2000 staff members. Based on a literature review, a hypothesis was put forward that a university city should have a high level of economic sustainability. To assess economic sustainability, the original methodology based on the US Cities Economic Sustainability Index (USCESI) was developed. It evaluates sustainability in three groups of parameters: society, economy, and ecology. The first group includes the level of racial diversity, the level of education of the population, and the access to medical services. The second group consists of the Gini coefficient by income level, the median cost of housing, and the unemployment rate. The environmental situation is assessed according to the Air Quality Index developed by the US Environmental Protection Agency. For comparison, the town of Braintree, MA, was chosen. As a result of the study, the USCESI was calculated for both locations. The analysis showed that both Amherst and Braintree have a high degree of economic sustainability. However, it was revealed that proximity to a significant economic center has a more powerful positive impact on economic sustainability than the location of a large university. In our paper, we proposed a new methodology for measuring economic sustainability with a special focus on inequality as a major problem in American society. The findings provide new knowledge about university cities and debunk the myth that they represent an exception to the general logic of urban development in the United States. A similar approach, with clarification of statistical indicators and a different emphasis, can be applied to other countries where inequality may be the main threat to economic sustainability, not in terms of access to higher education but in other areas.

  Studies of the properties and structure of mineral wool energy-efficient products /Scientific research of the SCO countries: synergy and integration

  In the modern world, increased energy efficiency and reduction of energy intensity are especially important in the construction industry, which largely determines the development of production as a whole. Reduction of energy intensity can be achieved through the use of efficient thermal insulation materials and products based on them and, in particular, mineral fiber products: based on glass or rock wool. The properties of these products are significantly influenced by the type and method of introduction of binder, and one of the ways to reduce the energy intensity of their production is to reduce the temperature of heat treatment of these products. The purpose of the research presented in this scientific paper is to analyze the existing types and methods of introduction of binders, aimed at reducing the energy intensity of the manufacture of products based on stone wool. As a result, a digital model linking the strength of cured contact with varying factors is obtained and a nomogram for solving the forward and inverse problem of digital modeling is developed, as well as optimal intervals of values of the most significant factors are determined: binder consumption 3.75%; content of latent component in the range from 3.6 to 4.0% of the binder mass at the temperature of heat treatment 120-140 o C.

  EXPLORING ASSOCIATIONS BETWEEN PARKING OCCUPANCY RATE AT RESIDENTIAL ESTATES AND SPATIAL CHARACTERISTICS. THE CASE OF YEKATERINBURG

  Financial losses due to low demand for parking spaces in garages at residential estates is a key motivation for this research. The purpose of this paper in particular is to statistically explore the relationship between parking occupancy rates and various factors on transport supply, characteristics of location and the building. The occupancy rate of parking was measured as the ratio of actual number of cars to total number of parking spaces. The fieldwork on counting occupied parking spaces was conducted 2 times per day during a week on a sample of 13 locations in different areas of a 1.4-million Yekaterinburg city in Russia. 4700 observed parking spaces give sample size of 173 records. Statistical analysis shows that the crow-fly distance to the city center as well as the number of public transport stops are strongly associated with occupancy rate for parking. Also, occupancy rate is much more affected by the type of parking ownership. Private owning means purchase of a parking space or renting it while public ownership suggests free access. So private parking means a 45% decline in occupancy compared to the public parking regime. Research provides empirical results and some theoretical underpinnings are also highlighted.
