Monolithic construction is one of the most promising technologies used in the construction of various buildings and structures. The emergence of a wide range of new materials and innovative construction technologies greatly simplify the process of monolithic construction of buildings and structures, making it more economical and fast. Concrete is one of the leading building materials. One of the main technical and technological tasks of production is to design the composition of concrete, improve its quality and reduce costs. The aim of the study is to develop recommendations for the design of concrete mixtures with a given mobility and a reduced risk of segregation of components in work processes. Theoretical and experimental study of the effect of a complex additive consisting of a Nano-modified superplasticizer and an air-entraining component on the rheological properties of the concrete mixture allowed to offer recommendations for the design of composite compositions. Nano-modified additive is a complicated complex of concrete with an axial compressive strength of 15–20 MPa. Application of a complex additive allows to receive concrete mixes with the set mobility and with a minimum risk of delamination. The exponential regression equation allows predicting the need for a Nano-modified additive to obtain the required mobility of the concrete mixture.
