COMMUNICATION OF PRODUCTION PROCESSES WITH GENERAL THEORETICAL TECHNOLOGY

The general laws and scientific principles underlying the theoretical technology are taken into account and used in determining rational parameters and regimes in production processes. It is because of this that there is a close interconnection between the numerous facts obtained at production and the general laws interpreted in theoretical technology. It predetermines, in the main, the spontaneous development of building materials science as a fundamental science of applied character. Most clearly, this relationship can be traced through the example of individual production operations.

1. Very common operations in production are the crushing and grinding of components at different stages of obtaining conglomerate mixtures; cement on dry and wet methods for the production of concretes; grinding of limestone or other mineral materials in the production of asphalt additives for asphalt concretes; fine grinding of pigment-pigments in the production of colorful substances for protective and decorative coatings; grinding of crystalline or amorphous silica, as well as the use of powder by-products of chemical industries (for example, AIF 3 , ferrosilicon, etc.) for the manufacture of soluble glass as an astringent in acid-resistant concrete, finishing materials, etc .; ultrafine (colloidal) grinding of fillers (silica, corundum, slag, some metals) in the production of Japanese cements of types A, B, MS, DSR, etc.

With increasing duration and intensity of grinding, the specific surface area and, correspondingly, the chemical and energy activity of the resulting ISK powder components increase. This factor, as already noted, is very favorable for the further development of spontaneous processes of dispersing particles up to their atomic-molecular level in the first solidification stage and for condensation processes - at its second stage (see 2.2.5,) with the formation of micro- and macrodispersed optimal structures.

2. From the production practice and experimental studies, a lot of often chaotically summarized facts were obtained, which, with a deep analysis, allowed us to formulate regularities that turned out to be not only common, but also objective, that is, occurring in natural conditions. They are mainly based on optimal structures. Regardless of the genesis of the formation of optimal structures, that is, in nature or in technology, they have a potential quality - improved (extreme) properties, which, however, is not yet always used in production conditions. As a result, often the quality of finished products is significantly reduced, the longevity of materials in designs is reduced. It is necessary that the optimal structure that is formed in the technological period, possibly more fully corresponds to the operational parameters and production conditions, that is, it was rational (see 2.3).
