FIELD: chemistry.
SUBSTANCE: present invention can be used in construction materials when making block and monolithic concrete. The composition contains cement, sand, water and carbon-bearing nano-material - soot, obtained using an electroarc method, and containing 7% of carbon nanotubes, with the following ratios of components, in wt %: cement 20-30, sand 50-70, carbon-bearing nano-material 1-2, water constitutes the rest.
EFFECT: increased compression strength of the construction material.
