Electromagnetic wave-absorbing ultra-high performance concrete and preparation method thereof
The invention belongs to the cross technical field of building material science and electromagnetic science, and discloses electromagnetic wave-absorbing ultra-high performance concrete and a preparation method thereof. The electromagnetic wave-absorbing ultra-high performance concrete is prepared from the following raw materials in parts by weight: 80 to 96 parts of UHPC premix, 0.1 to 0.3 part of graphene oxide and 1 to 3 parts of gamma-Fe2O3 nanoparticles. The preparation method comprises the following steps: adding graphene oxide and gamma-Fe2O3 nanoparticles into water, and carrying out ultrasonic dispersion to obtain a graphene oxide/gamma-Fe2O3 nanoparticle solution; and adding the mixture into the UHPC premix, adding water, uniformly stirring, and curing to obtain the product. The electromagnetic wave ultra-high performance concrete prepared by the invention has good wave-absorbing shielding function, ultra-strong mechanical property and larger wave-absorbing frequency band; the wave-absorbing property and the mechanical property of the wave-absorbing material can be regulated and controlled through the raw material ratio and the maintenance mode, and the wave-absorbing material can be used as a wave-absorbing and load-bearing material to be applied to building materials with special functions such as military blindages, airports, radar stations and large buildings.
本发明属于建筑材料科学与电磁科学的交叉技术领域，公开了一种电磁吸波超高性能混凝土及其制备方法。该电磁吸波超高性能混凝土的原料按照重量份包括：UHPC预混料80‑96份、氧化石墨烯0.1‑0.3份、γ‑Fe2O3纳米颗粒1‑3份。通过将氧化石墨烯和γ‑Fe2O3纳米颗粒加入水中，超声分散后得到氧化石墨烯/γ‑Fe2O3纳米颗粒溶液；随后加入至UHPC预混料中，同时加入水进行搅拌均匀，养护后得到。本发明制备的电磁波超高性能混凝土具有良好的吸波屏蔽功能和超强的力学性能，较大吸波频段；且其吸波性能和力学性能可以通过原料配比和养护方式进行调控，能够作为吸波及承重材料应用在军事掩体、机场、雷达站、大型建筑物等特殊功能的建材中。
