Embodiment 1

[0030] A preparation method of lightweight wave-absorbing aerated bricks, comprising the steps of:

[0031] Treatment of blast furnace slag: the blast furnace slag is crushed by a crusher, then sent to a ball mill, and ground to a slag powder with a particle size of 100 mesh; the composition of the blast furnace slag is: SiO 2 About 33%, CaO about 41%, alumina about 15%, MgO about 8%, S about 0.9%, iron oxide about 0.7%, and the balance is other;

[0032] Preparation of sludge ceramsite: dehydrate the sludge to a water content of 70wt%, then mix it with fly ash and clay in a mass ratio of 5:3:1, then stir at 200rpm for 5min, then add it to a ball mill and grind it to The particle size of the mixture is 50 mesh; then enter the drum granulator to granulate, control the particle size to 1mm, then place it at 90°C, dry it for 2 hours, then put it into a gas-fired rotary kiln, and calcinate at 1200°C for 15 minutes, Cool to room temperature to obtain sludge ceramsite;

Description

technical field [0001] The invention belongs to the field of building materials, and in particular relates to a preparation method of a lightweight wave-absorbing aerated brick. Background technique [0002] The electromagnetic waves generated by the interactive changes of the electric field and the magnetic field, and the phenomenon that the electromagnetic waves are emitted or leaked into the air are called electromagnetic radiation. Electromagnetic radiation is an invisible and intangible substance that exists in a special form. The earth itself, where human beings live, is a large magnetic field. The thermal radiation and lightning on its surface can produce electromagnetic radiation. The sun and other planets also continuously produce electromagnetic radiation from outer space. With the rapid development of modern electronic science and technology, high-frequency, digital, and electromagnetic radiation of electronic equipment create wealth for human beings, but also br...
