The invention relates to 3D-printable copper slag electromagnetic wave-absorbing concrete and a use method thereof. The concrete includes, by weight, 6.8-7.2 parts of quick-hardening ordinary Portlandcement, 6.9-7.1 parts of quartz sand, 1.65-1.75 parts of copper slag, and 0.28-0.71 parts of copper powder composed of brass powder and red copper powder according to the weight ratio of 7:2.5-3.5, 0.75-0.85 parts of silica fume, 0.09-0.15 parts of a water reducer, 0.04-0.07 parts of basalt fiber being 11-14 mm in length, 0.003-0.005 parts of hydroxypropyl methyl cellulose being 20,000-70,000 inviscosity, and 1.70-1.74 parts of water. With the copper slag and copper powder as raw materials, the concrete has both the printability and electromagnetic wave-absorbing effect of the copper slag and copper powder, so that the concrete allows 3D printing and can achieve more than 90% in electromagnetic wave absorption in the bandwidth of 3.4 GHz.
