“…As a result of the performed studies, the authors of [3,4,8,9,12,13,15] developed powder-activated concrete with a strength class of B100-B140 with a low specific consumption of cement per unit of compressive strength not exceeding 3-6 kg / MPa.…”

“…The formation of the structure of powdered concrete, the distinctive features of which are the higher dispersity of granular components, the increased value of the areas of the phase interface, the predominance of small and hidden cryptocrysts of neoplasms, the increased density, the increased number of physical and physico-chemical contacts per unit volume of material, creates a contradictory situation in which, on the one hand, the formed structure provides increasing compressive strength, and, on the other hand, makes it relatively more brittle, which can lead to a decrease in fracture toughness and impact strength [12][13][14][15][16].…”

The article presents the results of a study of impact strength of underground cement materials with different water content activated by mixing water with the addition of high range plasticizers, biocidal agents, pigments, ground quartz, silica fume and fine aggregate. Samples for testing are formed in plates of size 150×100×10 mm. Testing was conducted at impact drop-weight method ASTM D7136. The maximum contact force, contact duration and magnitude of the pulse of the drummer were considered as the test parameters. The good results of the studied parameters showed highly filled plasticized compositions of the new generation. The use of iron oxide with yellow and green glauconitic pigments allows obtaining good results. Activation of the mixing water led to a rise in the maximum contact force in the case of the processing mode of E+М (3–3) while reducing the duration of the contact and the magnitude of the impulse. During the test of the biocidal composites with different biocidal preparations, it was established that the best indicators of the impact strength correspond to materials with the addition of «Teflex Antiplesen».
