Materials for 3D Concrete Printing: Approach to Standardization in Russia Aleksey Adamtsevicha *, Andrey Pustovgarb, Liubov Adamtsevichc Moscow State University of Civil Engineering, 26, Yaroslavskoye Highway, Moscow, 129337, Russia aAdamtsevichAO@mgsu.ru, bPustovgarAP@mgsu.ru, cAdamtsevichLA@mgsu.ru Keywords: 3D printing, Testing methods, Materials for 3DCP, Rheology, Fresh concrete, Mechanical properties.
So, when researching in a laboratory of Research Institute of Building Materials and Technologies of Moscow State University of Civil Engineering, resistance of materials for 3DCP to cracking under extreme conditions when applied in a thin layer (less than 1 cm) on a substrate, high water absorption has been observed to affect the integrity of the layer even small air fluctuations in the laboratory, as well as individual irregularities in the surface of the substrate (Fig. 2).

The radiologic detector was selected from market available solutions, following a requirements matrix developed in a partnership of end-users and engineers (Table 4).
The field tests took place at the Lisbon Naval Base (BNL, Base Naval de Lisboa) in the Portuguese Navy's Damage Control School (Escola de Limitação de Avarias) and Tancos area in the Portuguese Army's 1st Engineer Regiment (Regimento de Engenharia n.º1).
