Electromagnetic shielding concrete and preparation method thereof
The invention discloses electromagnetic shielding concrete and a preparation method thereof, and belongs to the technical field of concrete. The electromagnetic shielding concrete provided by the invention is prepared from the following raw materials in parts by mass: 1020-1050 parts of granite macadam; 750 to 850 parts of granite machine-made sand; 250 to 380 parts of cement; 50 to 90 parts of granite saw mud; 150 to 190 parts of water; 5-10 parts of a water reducing agent; 6-8 parts of carbon fiber; and 0.8-1.2 parts of a dispersing agent. The granite waste is introduced into the concrete material in different particle sizes, under the combined action of various forms of mineral components and carbon fibers of granite, high electromagnetic shielding effectiveness (1GHz electromagnetic shielding effectiveness reaches 30dB or above, and 2GHz electromagnetic shielding effectiveness reaches 45dB or above) can be played, the concrete has high compressive strength, a large amount of granite waste can be consumed, and the cost is reduced. And the method has good application value.
本发明公开了一种电磁屏蔽混凝土及其制备方法，属于混凝土技术领域。本发明提供的电磁屏蔽混凝土，其由以下质量份组分的原料制得：花岗岩碎石1020～1050份；花岗岩机制砂750～850份；水泥250～380份；花岗岩锯泥50～90份；水150～190份；减水剂5～10份；碳纤维6～8份；分散剂0.8～1.2份。本发明将花岗岩废料以不同的粒径引入到混凝土材料中，在花岗岩各种形式的矿物组分和碳纤维的共同作用下，不仅可以发挥高电磁屏蔽效能(1GHz电磁屏蔽效能达30dB以上，2GHz电磁屏蔽效能达45dB以上)，而且具有高抗压强度，还能够大量消纳花岗岩废料，具有良好的应用价值。
