Description

technical field [0001] The invention belongs to the cross technical field of the combination of electromagnetics and material science theory, and specifically relates to a wave-absorbing concrete and a preparation method thereof. Background technique [0002] Absorbing concrete is a building functional material that converts electromagnetic waves into other forms of energy and dissipates electromagnetic waves. It has important civilian uses for the protection of buildings, the purification of electromagnetic pollution, the confidentiality of electromagnetic information, and the invisibility of ground military buildings. with military significance. Therefore, the development of new low-cost, high-efficiency, and lightweight absorbing concrete has broad prospects for development. At present, the research on traditional wave-absorbing concrete is mainly to add fine carbon wire, iron wire, chiral helical coil, nano-wave absorbing agent, composite wave-absorbing agent, etc. to t...
