Electromagnetic wave-absorbing ceramsite concrete
The invention belongs to the field of building interior and exterior wall body surface concrete building materials, and particularly to a concrete material capable of absorbing electromagnetism. According to the present invention, a silicate cement clinker and electric conduction graphite or electric conduction carbon black are subjected to ball milling to obtain an aqueous cementing material having electric conductivity, and the aqueous cementing material and a ceramsite aggregate having multi-level micro-pores are prepared into the electromagnetic wave-absorbing ceramsite concrete according to a certain ratio, wherein the aqueous cementing material has a certain electric conductivity, the specific surface area of the ceramsite aggregate is two times larger than the specific surface area of the aqueous cementing material, the aqueous cementing material having the small specific surface area is doped into the ceramsite micro-pore having the large specific surface area so as to make the ceramsite aggregate have the dielectric property, and the electromagnetic wave enters the ceramsite aggregate having the dielectric property and then is absorbed and converted into the heat energy so as to provide the electromagnetic wave absorbing effect.
