USE OF MONOLITHIC FOAM CONCRETE IN ENCLOSING STRUCTURES OF BUILDINGS AND STRUCTURES WITH VARIABLE THERMAL CONDITIONS
VYTCHIKOV Y.S., SAPAREV M.Y., GOLIKOV V.A.
Abstract
This article considers the features of the use of monolithic foam concrete as a heat-insulating layer in the building enveloping structures of buildings operated under intermitt ent heating conditions. To assess the eff ectiveness of the use of monolithic foam concrete in building enveloping structures, a thermal engineering calculation of the outer wall, insulated with the use of monolithic foam concrete, was carried out. Based on the calculations carried out by the authors, graphs of the dependence of the heating time of multilayered enclosing structures on the thickness of the heat-insulating layer and the reduced resistance to heat transfer of the structure were obtained. The optimum range of thicknesses and densities of monolithic foam concrete for thermal insulation of external walls of buildings, operated in conditions of intermitt ent heating, is off ered. This calculation also showed that the use of foam concrete as a heater from the inside of the outer wall can reduce the load on the foundation of the building.

ABRAMENKO A.A., VOLKOV V.V., BRITVINA (.E.
Abstract
Currently one of the tasks of materials science is to fi nd ways to reduce the cost of building materials. Studies have shown that the initial strength of the starting components does not aff ect the properties of the material. The article presents a study of the physicochemical processes occurring on the surface of dispersed components, the infl uence of the thickness of water fi lms on the strength of the fi nal material. The interdependence between the area of the endo-eff ects of thermograms and the strength of the materials obtained is considered. A model of interaction in dispersed systems is proposed, which allows one to infl uence the structure formation of composite materials in a targeted manner. Research is aimed at studying the patt erns of physicochemical processes on the surface of fi ne particles, the understanding of which allows us to predict, and subsequently set the properties of the materials obtained.

HEAT-RESISTANT COMPOSITIONS BASED ON WASTE OF ENTERPRISES OF CERAMIC INDUSTRY
KHLYSTOV A.I., ISAEV D.I., PODGORNAYA D.A.
Abstract
The article presents various methods of synthesizing heat-resistant binders based on large-tonnage wastes of the ceramic industry. The use of expanded clay dust in the compositions of heat-resistant concrete on portlandcement allowed to increase their residual strength in the zone of critical temperatures (800-1000 ° C). It was revealed and justifi ed that the use of phosphate binders for synthesizing a binder made it possible to increase the refractoriness of the heat-resistant composition based on expanded clay dust to 1300-1350 с. As the experiments show, claydite dust in its composition contains a clay component, which ensures the plasticity of the ramming mass. It was established that samples of ramming mass on orthophosphoric acid did not require heat treatment and can be immediately removed.

TOWER BUILDING IN THE MODERN CITY: THE IMPERFECTION OF THE IDEAL
KOTENKO I.A.
Abstract
The article views the tower building as one of the modern methods of planning residential areas. The uniqueness and signifi cance of the vertical form in the composition of the city at all historical stages of its existence are noted. The author considers the evolution of the tower as an element of the composition from the unique to the mass use and the formation of the reception of urban planning composition. Due to its infl uence on the surrounding space, panoramas and silhouett es of the city, tower building retains its special urban planning value. Recently, in almost all Russian major cities, there has been an interest in this planning technique, which is increasingly called high-rise buildings and has an ambiguous assessment in a historic city. The article discusses modern examples of tower building in Samara and analyzes the problems of its urban planning application.

SOCIO-CULTURAL PHENOMENON OF HISTORICAL TERRITORIES. WOODEN FORTRESS OF SAMARA
MALYSHEVA S.G., SHLIENKOVA E.V.
Abstract
The architectural and planning features of wooden fortresses of the city of Samara, built next to each other with a time interval of 120 years, are considered. The origins of one of the unique spatial characteristics of Samara, a special historical code of development of its territory, are analyzed, when at each new stage of development in the city a new center was formed with a consistent movement higher and higher along the watershed from the arrow of the Volga and Samara rivers. The emergence of this spatial expansion is justifi ed by the construction of a second wooden fortress as a new urban center, but not in the place of the burnt fi rst fortress, but in the neighboring territory after 200 m. Since at the moment both fortresses have not survived, with the exception of basement fragments , the authors analyze the possibilities of a new reading of the “memory of the place” and the restoration of the cultural and genetic code of the city that was lost in due time. The article proposes an algorithm for the development and subsequent comprehensive implementation of the historical and cultural strategy of urban development, based on the creation of unique models of public spaces that can connect the past and the present in a new spatial paradigm. The concept of an interactive platform is considered with the aim of promoting a sociocultural project and drawing public att ention to the problem of the irretrievable loss of the historical and cultural heritage.
