FIELD: manufacturing technology.
SUBSTANCE: invention relates to radar-absorbent composite material for construction applications. Radar-absorbent composite material for construction applications is obtained from a mixture consisting of a binder based on a cement-carbon material, mixing water and filler. Cement with carbon nanotubes attached to its surface and nanofibers in an amount of 0.1–10 wt% of cement are used as a cement-carbon material. Ferrite powder or carbonyl iron, or a mixture thereof is used as a filler. Initial components are taken in the following mass ratio: cement-carbon material: functional radar-absorbent filler: mixing water 1:(1.5–4):(0.4–0.7), respectively.
EFFECT: technical result is increased radar-absorbent properties and strength characteristics.
