“…As an additive chalk of the Slavyansk deposit is used, pigment is used ocher, it is clay colored with iron oxides which has various shades from light yellow, golden to dark, red and even brown. In concrete, a mixture of highly dispersed chalk is introduced as a chalk suspension [8,9].…”

“…Samples of cement stone were made from Portland cement without additives and with the addition of chalk: 1control sample made of Portland cement without additives; 2, 3, 4, 5 -with the addition, respectively, of 10, 20, 30, 40% of chalk from the total mass of cement and chalk at W/C=0.45. After solidification under normal conditions for 28 days, the samples were crushed and for the following researches, fractions of 0.14-0.315 mm were, after which a quantity such particles were placed in measuring cylinders with aggressive solutions [8,9].…”

During the war active, a huge number of residential and public buildings were destroyed not only in Kharkiv and the region, but throughout Ukraine. For the restoration of destroyed buildings, new types of cement will be needed to look for and will be created decorated concretes based on them that would provide high operational and technological properties of constrictions and will be focused on local materials. Carbonate additive such as highly dispersed calcite (chalk) can be used for as local additive for concrete due to significant reserves are located in Kharkiv region. In the article research on the impact of joint action additive of highly dispersed calcite (chalk) and natural pigment (ocher) is presented by physical and mechanical properties such as density, strength, water resistance, and frost resistance. It has been established that, depending on the percentage of highly dispersed calcite (chalk), the physical and mechanical properties are changed irregularly. On the basis of the conducted researches it was established that the optimal amount of the addition of high‐fossil chalk, which provides increased frost resistance and corrosion resistance of concrete in an aggressive environment, containing chlorides, sulfates and magnesium ions, is from 10 % to 30 %. In addition, it increases density, compressive strength, stretching strength at bending. At the same time, it should be noted at an increased amount of fine chalk to 40% leads to a decrease in physical and mechanical characteristics. But the introduction of plasticizer in the amount of 0.5% leads to increased compressive strength and, accordingly, increases the positive qualities of chalk. The concrete compositions that getting with high decorative and operational properties are allowed to use them for the restoration of the city and increase in urban space.

“…The performance of VR technology in landscape architecture planning and design only stays in the roaming stage of "having a look", and most of them lack the dynamic shaping of landscape and the display of landscape culture. Not pay attention to show the "people-oriented" principle of garden green space and garden art [8] . No information query function.…”

With the increasing complexity of human settlements and the deterioration of the ecological environment, landscape design shoulders the arduous responsibility. However, due to various reasons, the digital process of landscape planning and design has lagged behind the times. This paper discusses the difficulties of artificial intelligence reconstruction design in current landscape design, and points out the necessity of promoting artificial intelligence reconstruction design in landscape design. This paper defines the definition, characteristics and concept pedigree of landscape architecture artificial intelligence reconstruction design, analyzes the main digital design methods and application software platform in the concept pedigree, and summarizes the flow chart of landscape architecture artificial intelligence reconstruction design based on VR technology and wireless communication technology. Finally, the limitations and misunderstandings of current AI reconfiguration design are analyzed.
