High-Rise Construction in the United Arab Emirates
Abstract
A review of high-rise construction in the United Arab Emirates has been carried out. The tallest and most unique buildings, their individual design solutions are considered. The main reasons and trends in the development of high-rise construction in the United Arab Emirates are identified.
Use of Thermal Insulation Vacuum Panels in Enclosing Structures
Abstract
The analysis of thermal insulation materials is carried out, taking into account the coefficients of thermal conductivity and compressive strength. The possibility of using vacuum insulation panels in wall enclosing structures is considered. The thermal engineering calculation of the external walls of a residential building is provided.
Introduction of Information Modeling Methods in Foreign Countries
Abstract
The article considers the main global trends in implementation of information modeling technologies in foreign countries. The authors outline the main support measures from the state for the most rapid and rational transition of the construction industry to BIM technologies. A model describing the maturity levels of BIM technology is also considered.
The Effect of Microsilica on Frost Resistance of Masonry Mortar
Abstract
This article examines the effect of microsilica obtained on the basis of modified natural diatomite on the basic characteristics of the mortar. The change in the elemental composition of diatomite during its modification is provided. The effect of diatomite modification on the change in the pore space of cement stone is shown.
Technology of Shopping Center Modeling in the Autodesk AutoCAD and ArchiCAD Systems
Abstract
The formation of an information model of the shopping center in AutoCAD 2018 and ArchiCAD 24 systems is completed. The technological sequence for creating the model is determined. The simulation results are presented. A comparative analysis of the models is carried out.
Effects of Polycarboxylate Flexibilizer and Mineral Additives on Strength Characteristics of Cement Composites
Abstract
The paper presents the results of a study of the effects of mineral additives of various compositions (silica, aluminosilicate, sulfoaluminate, carbonate) and polycarboxylate flexibilizer on the mobility, density, and compressive strength of cement systems. Optimal concentrations of additives, which make it possible to obtain modified cement composites with increased strength indicators, have been found.
Cyclic Tests of Epoxy Polymers
Abstract
The character of the deformation curve of epoxy polymer samples under soft cyclic asymmetric loading to the stress level of 80% of the breaking load is estimated. The change in energy losses due to hysteresis with an increase in the number of cycles is analyzed for the composition of an epoxy polymer based on Etal-247 epoxy resin cured by Etal-1472.
Effects of Technological Modes on Elastic-Strength Characteristics of FDM-Printed Samples
Abstract
The effects of technological modes, such as temperature, speed and orientation of printing on the change in the elastic-strength indicators of FDM-printed samples are studied. Tensile strength and modulus of tensile elasticity, elongation at break and maximum tensile load were recorded. The optimal printing modes are revealed, taking into account the orientation of FDM-printing.
