The purpose of this article is to consider the concept of "polymer concrete", its classification, features of its use, role in modern construction and the likelihood of replacing traditional building materials. Also studied and structured theoretical material on the topic "concrete based on polymer binders", classification of polymer concrete according to V.V. Paturaev ,practical experience of its application. The possibility of using polymer concrete in modern realities and in the future is considered. General conclusions are made about the expediency of its widespread use from a practical and economic point of view.

The purpose of the article is to study the material on the topic "Basalt fiber", to generalize the studied material and the accumulated experience on the given topic. The article discusses the advantages, disadvantages, problems of use and achievements in the study of basalt fiber used for the production of building materials as a reinforcing component. The analysis of the average cost of basalt fiber in comparison with other types of fiber is carried out, a conclusion is made about the advantage of using basalt fiber. General conclusions have been made about the advisability of using basalt fiber for the production of building materials, and unexplored areas of using this type of fiber have been identified.

The paper argues for the relevance of using volumetric modular units (VMU) in construction, especially in building temporary field camps. Despite a high installation technology intensity, the use of VMUs is said to demonstrate a low technology intensity in terms of transport operations. In order to ensure a high transport flexibility for temporary settlements, collapsible volumetric modular units are suggested as a potent solution.

The paper is based on a review of the scientific publications released from May through October 2019, the greater part of which, namely 14 papers, is included in the Web of Science scientometric database. The authors of the papers analyzed explore the construction industry problems over the past 5 years. The foreign studies listed in the reference section were based on the analysis of reviews falling in the above-mentioned timeline. The purpose of this paper is to identify the problems hindering the implementation of BIM technologies in the construction sector, not only in the foreign countries, but also in Russia.
