Characteristics of magnetic separators are analyzed in the article. Magnetic separators are used to treat various construction materials. Unfortunately, the nature of the magnetic field, generated in their operating zone, is generally not taken into account by their designers. Academic publications fail to provide any detailed basic characteristics of the field induction emitted by magnetic separators in the course of their operation.Magnetic systems of any magnetic separator have a modular structure; they consist of several modules. Single and opposite magnetic elements are usually integrated into one module within a system having permanent magnets. If opposite magnetic elements are used, magnetic field intensity inside the module increases.In this study, characteristics of magnetic induction for single magnetic elements inside various modules of magnetic separators were assessed in a laboratory experiment. Similar characteristics of magnetic induction for single and twin (opposite) magnetic elements were compared. In the module consisting of two opposed magnetic elements, the magnetic field becomes stronger compared to the field of a single magnetic element. Magnetic induction in the module recedes as the distance between magnetic elements increases, because of the isolation of the field generated by the opposed magnetic elements.The authors have proven the feasibility and expediency of employment of the superposition principle used to obtain the resulting characteristics. It may be employed to substitute modeling by calculations.

The article represents the overview of unification and standardization processes, and their impact on the construction sector in the new social and economic environment of Russia. The expediency of compilation of regional construction catalogues as the drivers of accelerated construction works, construction quality improvement, and profitability. The proposed methodology and the expert opinion principles that serve as its basis may be applied to other sections of regional (territorial) construction catalogues. No national economy, regions or territories can pursue their development absent of the construction sector; therefore, a scientific approach to the organization of the process of designing, construction and operation of buildings and structures on the basis of regional unification and regional catalogues of solutions encompassing construction operations, structures and products are of particular relevance.
