The property control of concrete mix and hardened concrete is an integral part of the construction process. With the development of additive manufacturing in construction, the methods of assessing the properties of concrete mix and concrete are characterized by the formation of their structure and properties in concrete laying and curing. Currently, there is no regulatory documentation on a reliable assessment of the concrete mix and concrete quality for additive manufacturing. The purpose of this work is to propose a method for determining the concrete strength for additive manufacturing. The proposed concrete mix composition matches the technological requirements for 3D printing equipment and possesses the required properties. The concrete strength analysis and research methods are carried out in accord with the Russian State Standard. The paper describes the main problems of the concrete quality control in using additive manufacturing and proposes methods for determining the concrete strength properties for 3D printing.
