Abstract

The paper presents experimental studies on optimizing the structure of a polydisperse fine grain concrete mix for 3D printing of structures with the production of a dense cement conglomerate providing high plastic and cement strength, as well as stable geometry of the layers and the structure in general. Optimization was performed at the micro level by introducing limestone meal as a filler with a grain size of up to 60 microns, and at the macro level by selecting the ratios between the three basic fractions of quartz sand (0.16–0.315: 0.315–0.63: 0.63–1.25) according to the maximum bulk density of the fraction mix. Arranging the fine grain mix components according to their proportionality at each scale level of the structure allowed us to obtain a conglomerate with 40% higher bending strength and 23.8% higher compressive strength than the control composition. The grain packing density and obtained fractal structure also allowed us to halve water absorption during capillary suction. The resulting composition of the polydisperse fine grain concrete mix serves as a basis for further modification with chemical additives to obtain a viscous-plastic mix with specified rheotechnological characteristics meeting the requirements of additive 3D printing by layer-by-layer extrusion.
