3. Discussion and results 3.1. Concrete

Results of mechanical tests of the unmodified and modified heavy concrete M200 by composition “Silor-Ultra KM” under the compression and bending are given on Fig. 1 and Fig. 2, that was studied by Kuzmin et al (2016, 2019).

Fig.1 the Chart of durability on M200 concrete compression

From the Fig. 1 it is visible that durability at compression of the modified material increases in comparison with unmodified by 28%. From the chart, it is visible, that the durability of the modified samples concrete by a bend increases twice.
