he concrete pumping principle of transporting and laying concrete mix is promising for implementing in monolithic construction and factory production of precast concrete products. Its implementation makes it possible to mechanize the most labor-intensive concreting processes, reduce labor costs, and improve the quality of work. The technical effect of concrete pumping technology is achieved when using concrete mixes of a specially selected composition. They must meet a number of technological requirements, including: high fluidity, increased concrete mix cohesion, and non-segregation of the mixture. The complexity of determining and accounting for production factors that affect the properties of the concrete mixtures pumped and the indicators of the purpose of concrete, makes it impossible to design their composition according to GOST 27006–2019 and requires an individual approach. An experimental evaluation of the effect of superplasticizers of different chemical nature on the pumpability of mixtures and the physical-mechanical properties of concrete was performed. The possibility of obtaining self-compacting mixtures is considered. The studies were performed using superplasticizers of the TECHNONICOL brands (based on sodium poly-naphthalene methylene sulfonate) and BASF (based on polycarboxylate ether). Fly ash from Novocherkasskaya GRES was used as a mineral filler. The use of superplasticizers of both brands ensured the production of pumped mixtures. Self-compacting mixtures (with the required spreadability) were obtained only in compositions with the addition of the BASF trademark. The influence of the consumption of the components of concrete mixtures on their properties and the properties of concretes is established
