The paper is devoted to the results of microscopic analysis structure fire-resistant materials developed on basis local mineral raw materials. authors point out that in this regard, a special place occupied by refractory materials, because use various radiation and designs microscopes from optical electronic requires preparation objects methods for deciphering observed images. Moreover, these r...

The possibility of using local materials in the construction structural layers pavement is considered paper. paper presents a method technical and economic analysis, for which it necessary to know calculated deformation moduli being compared. Knowing turnaround time each options under consideration, possible, by comparing them with payback periods, more fully identify features such options. mai...

Impregnating composition with water-soluble binders has been elaborated, the help of which source deflation mobile sands is blocked, and protective crust obtained on sandy surface characterized by resistance to effects wind-sand flow, assessed plastic strength thickness. The free-flow movement a binder in porous body sand depends mainly equivalent diameter particles joint solution internal exte...

Abstract We propose a new metric called s -LID based on the concept of Local Intrinsic Dimensionality to identify and quantify hierarchies kinematic patterns in heterogeneous media. measures how outlying grain’s motion is relative its nearest neighbors displacement state space. To demonstrate merits over conventional measure strain, we apply it data individual grain motions set deforming granul...

The application of the density-functional theory in the local approximation to magnetic materials is discussed and illustrated by examples. The magnetic properties of the 3d elemental metals as well a s their cohesive properties are described by means of self-consistent local-spin-density (LSD) calculations and by using the LSD-Stoner method. The application of the LSD approximation to narrow-b...

Fluctuations of the local volume fraction within granular materials have previously been observed to decrease as the system approaches jamming. We experimentally examine the role of boundary conditions and interparticle friction μ on this relationship for a dense granular material of bidisperse particles driven under either constant volume or constant pressure. Using a radical Voronoï tessellat...
