The work is the result of a multi parameter analysis of scientific publications affecting the study of the properties and characteristics of composite binders and concretes based on them, used in the design and production of small architectural forms. General assessment of the prospects for the use of composite binders in this type of buildings and structures is given. All publications and experimental materials on this topic are summarized according to the following parameters: bibliometric indicators of articles for the period from 2000 to 2020, types of concrete used for small architectural forms, types of binders, aggregates, fillers and additives used, physical and mechanical properties and controlled parameters of concrete. It is shown that in most of the studies under consideration, fine-grained concrete based on white, general construction and non-ferrous cement was used. At the same time, to increase the efficiency of finished products in terms of the formation of a developed shape and ensure their weather resistance, high-quality cements are used, the water-cement ratio decreases, including due to the use of additives for various purposes. It is substantiated that designing of concrete for small architectural forms should be carried out based on the specified requirements for this type of structures. The production of high-workability mixtures should be considered to ensure the specified castability in order to form products of various configurations and standard sizes while maintaining architectural expressiveness and compliance with the modern landscape of urban space.
