This article deals with the questions of creation and use of decorative and finishing concrete and mortar. It has been revealed that the most effective artificial rock-imitating stone materials are those made of decorative concrete with the opened internal structure of material. At the same time it is important that the particles of decorative aggregate should be distributed evenly in the concrete volume. It can be reached only at a continuous grain-size analysis of the aggregate from the given rock. The article tackles the necessity of natural stone materials imitation for the cement stone color to correspond to the color of the rock. The possibility of creation of the decorative concrete imitating rocks in the high-speed turbulent mixer is considered. Dependences of durability and frost resistance of the studied concrete on the pore size and character and also parameters characterizing crack resistance of concrete are received.

It is known that enamel coatings with enhanced protective and decorative properties can be fabricated on the basis of boron-silicate glass frits with an increased content of TiO2 in their composition. Opacity and white color of enamel coatings are due to their crystallization at firing temperatures. Titanium glass enamels are not pure white visually, and show yellow and blue shades depending on their chemical composition. The purpose of this work was to establish the influence of basic components on the water resistance and color characteristics of titanium enamel coatings. Our experimental study was focused on the glass frits with the chemical composition described by the generalized formula (76–n–m)SiO2nB2O3mNa2O24MexOy, where MexOy is the total content of TiO2, ZrO2, Al2O3, MgO, СaO, P2O5, and K2O. It was found that the glass frits with the following content of basic components (mol.%): Na2O 12–13, K2O 3, B2O3 10–11, SiO2 49–51 demonstrated the highest water-resistant properties. The color characteristics of titanium enamel coatings prepared on the basis of the mentioned glass frits differ significantly from the reference white light A; the titanium enamel coatings under consideration have a yellow-green tint. The highest deviations of the enamel coating color purity and color tone from a standard of white color were observed when increasing the Na2O content in the glass frits composition at the expense of SiO2. The color of titanium coatings with the highest water resistance has a deviation from the standard of white color within 4–6%.

The construction industry is demanding more and more quality decorative cements. The demand for them and the requirements for their performance are constantly growing. But since decorative cements are based on white Portland cement, their production is associated with the disadvantages of the production of all clinker cements low environmental friendliness, high energy consumption and high prices. They are not always able to provide decorative ecological and comfortable coatings with increased performance. In addition, many countries do not produce it and have to import it. An effective alternative to decorative clinker cements can be decorative slag-alkaline cement obtained from industrial waste. It also provides a number of special properties a wide range of colors, color fastness, high strength, high adhesion, durability and many others. But the problem associated with the use of slag-alkaline cements as decorative cements with high linen ( 70%) is the unstable chemical composition of the slag and, first of all, the different presence of iron oxides in it. It is shown that the presence of iron oxides can reduce the whiteness of decorative slag-alkaline cements due to the synthesis of compounds in them, which give the samples of blue-green color and due to the presence of iron oxides proper, which are inherent in color from brown to dark brown. The paper shows the regularities of the influence of the chemical composition of blast-furnace slags on the whiteness of an artificial slag-alkaline stone. Possibilities of obtaining decorative alkali-activated cements with a wide range of whiteness from 70 to 97% are shown. Methods of reducing the cost of slag-alkaline decorative cements by using a complex bleaching additive, where part of the expensive TiO2 can be replaced by kaolin or CaCO3, are shown. A new method for determining the whiteness of hardened materials is proposed.

The paper presents the study on the identification of patterns of coloring of a basic glass matrix and enamel coatings based on it in the system R2O–ВаО–ZnO–Al2O3–В2О3–TiO2–SiO2 by a number of ionic dyes. Regardless of the dye content, ionic dyes give the same color tone to both glasses and coatings based on these glasses as follows: CuO (1.0–3.0 wt.%) =489–494 nm (blue-green), Fe2O3 (0.5–2.0 wt.%) =575–585 nm (yellow), K2Cr2O7 (0.5–2.0 wt.%) =570–576 nm (yellow-green), CoO (0.5–1.0 wt.%) =441–463 nm (blue-violet), and NiO (0.5–1.0 wt.%) glass=559'–571' nm, coatings=598–629 nm (brown). It is shown that according to the degree of color intensity of glasses and coatings based on them, the dyes are arranged in the following sequence: CoO>NiO>CuO>K2Cr2O7>Fe2O3.. The research was conducted using a special computer program COLOR GLASS. The established patterns are used in the development of lead-free glass enamels for jewelry and decorative products.

White building components, whether decorative or the overall structure, are susceptible to extreme weathering conditions, which affect the durability of the building’s external surface. In particular, white natural stone materials can provide buildings with beauty, durability, and sustainability, but this beauty is affected by key factors determining their weather resistance, namely physical properties such as porosity and acid and alkali resistances. As indicated by a past study, marble used as the exterior wall of a building in a similar environment will exhibit tarnishing after six months of weathering. Taiwan is a subtropical island, so the weather resistance of building materials to this environment is worthy of attention. As pointed out by the study, raw stone materials containing zirconium and silica can have greater weather resistance, do not easily change color, and possess good stress resistance properties. Focusing on this, this study attempted to identify stone materials with such compositions and sent samples to SGS (Societe Generale de Surveillance S.A., New Taipei City, Taiwan) for testing of weather resistance. This paper uses Spanish artificial stones for the study and observes the changes in the surface cleanliness on two buildings in Yilan County and Taipei in Taiwan after exposure to sun and rain. The experiments were conducted over two years. The study results showed that the artificial stones displayed no change in outward appearance under both rainy and acid rain environments. In Yilan, construction of an exterior wall was carried out in February 2018. The exterior wall used the white artificial stone directly from the manufacturer, and the black artificial stone with added paint for stone protection. After two months, the black artificial stone covered with paint exhibited a change in color and stains appeared on the surface, while the white artificial stone not covered with paint maintained the same cleanliness after two years. In Taipei, white Spanish artificial stone was used for the exterior wall of an entire building block in February 2020. After the frame was dismantled in September 2020, the color was found to be unaffected, being as pure white as it was when new. Therefore, this study selected Spanish artificial stone for the design of a building’s exterior wall, as the cleanliness of the stone surface is not affected and it has good applicability in rainy and acid rain island environments.

New genotypes of peach, which are sources of cytoplasmic male sterility (CMS), were selected; large-fruited peach I4 970-89 was isolated, as a pollinator for genotypes with male sterility; in the population of hybrid seedlings F2 (peach of the world x David peach) we identified new genotypes of plants with absent characters in their original species; with resistance to powdery mildew and leaf curl, dwarf plant growth, forms with decorative double flowers, white, pink and purple-red color of the petals of the corolla, bell-shaped and rosy flower types, male sterility, pollen fertility and honey taste of the fruit inherited from his wild ancestor - David peach. Summary. Selected maternal genotypes of the original parental forms of apricot, with a character of CMS - 189-88, 249-81, 498-86. They are of breeding value for the development of new peach cultivars. Peach I4 970-89 of the Nikitsky Botanical Gardens’ breeding is a pollinator for hybrids of peach with common almond, characterized by male sterility. Valuable characters of David peach could be transferred to common peach and its cultivars as a result of natural hybridization due to their joint growth in the primary Chinese-Japanese genetic center. From wild ancestor, David peach common peach cultivars inherited such valuable characteristics as resistance to powdery mildew and leaf curl, dwarf growth of plants, shapes with decorative double flowers, white, pink and purple-red petals of the corolla campanulate and rose-like types of flower, male sterility, pollen fertility and the honey taste of the fruit.

Experiments were carried out to determine the rational range of the proportion of fillers from sand and the dropout of crushing concrete scrap as a replacement part of the cement to obtain colloidal cement glue and to assess the effect of fillers of different specific surface area and the degree of filling on the kinetics of the set of strength of the hardened stone. It is established that the composition of the concrete scrap crushing drop-out contains about 30% of non-hydrated Portland cement, which deter-mines its use as an active micro-filler in the production of fine cement sys-tems. According to its chemical composition, the elimination of crushing of concrete scrap from heavy concrete is presented in the form of com-pounds of oxide groups, which, as a result of the interaction, provide the process of solid-phase synthesis of new compounds and are not able to en-ter into chemical interaction with pigments, the color of which is deter-mined by the type and content of iron oxides, and therefore has no contra-indications for use in decorative thin-milled cement systems.

This chapter concentrates on the non-imperial demand for stone in the Roman world, to provide some context for understanding the imperially orchestrated stone trade. Two related trends underpin the fashion for stone use: a widespread growth in demand for stone of all types, especially during the first three centuries AD; and targeted and disproportionately high demand for high-quality decorative stones. Imperial building projects played a major role in this process, setting the tone for much non-imperial activity; they have the highest densities of decorative stones and have consequently attracted most scholarly attention. However, in aggregate terms more stone was consumed by the non-imperial market; the bulk of this material moved only short distances to satisfy local demand. The level of demand for high-quality or uniquely patterned stone from imperial building projects, primarily at Rome, distorts the picture of small-scale, localized quarrying and the typically limited pattern of distribution that was the norm.
