Electromagnetic shielding mortar
The invention relates to the field of building materials, and discloses electromagnetic shielding mortar which is prepared from the following materials: a cementing material, water, river sand, nano ferroferric oxide, micron ferroferric oxide and a polycarboxylate superplasticizer, the ratio of each material is as follows: 831.79 kg/m < 3 > of the cementing material, 340.47 kg/m < 3 > of the water, 987.24 kg/m < 3 > of the river sand, 19.90 kg/m < 3 > of the nano ferroferric oxide, 49.75 kg/m < 3 > of the micron ferroferric oxide and 0.90 kg/m < 3 > of the polycarboxylic acid high-efficiency water reducing agent. Compared with common mortar, the slump of the mortar is improved by 3.57%; the compressive strength of the cube in 28 days is improved by 20.53%; the maximum absorption peak value of electromagnetic waves is-45.6 dB, the bandwidth of a frequency band with the reflectivity lower than-10 dB is 11.16 GHz, and the bandwidth is improved by 404.98%.
本发明涉及建筑材料领域，且公开了一种电磁屏蔽砂浆，其由以下材料制备而成：胶凝材料、水、河砂、纳米四氧化三铁、微米四氧化三铁以及聚羧酸高效减水剂，各材料的配比为：胶凝材料831.79kg/m3、水340.47kg/m3、河砂987.24kg/m3、纳米四氧化三铁19.90kg/m3、微米四氧化三铁49.75kg/m3以及聚羧酸高效减水剂0.90kg/m3。本发明与普通的砂浆相比，砂浆的坍落度提高了3.57％；28天立方体抗压强度提高了20.53％；对电磁波的最大吸收峰值为‑45.6dB，反射率低于‑10dB的频带带宽为11.16GHz，提高了404.98％。
