Abstract

The invention relates to electromagnetic-wave-radiation-resistant dry-mixed mortar making use of barium slag. The electromagnetic-wave-radiation-resistant dry-mixed mortar is composed of, by weight, 40-55 parts of solid solution, 15-25 parts of iron tailings, 20-38 parts of gypsum, 0.2-0.5 part of cellulose ether, 0.1-1.5 parts of silicon carbide fibrous crystal, 0.05-0.6 part of a foaming agent, 0.2-1 part of graphite and 0.04-0.06 part of a retarder, wherein the total amount of the components is 98-102 parts. The solid solution is obtained by mixing and firing iron tailings, the barium slag and boron oxide of which the mass ratio is (1-1.4):(6-6.6):(0.012-0.02). The electromagnetic-wave-radiation-resistant dry-mixed mortar making use of the barium slag is good in radiation resistance, excellent in mechanical property and capable of being widely applied to industrial and medical radiation-resistant engineering; besides, the industrial waste slag is used so that benefits can be brought to society.

Description

technical field [0001] The invention belongs to the field of building materials, and in particular relates to a dry-mixed mortar using barium slag to resist electromagnetic radiation and a preparation method thereof. Background technique [0002] With the rapid development of science and technology and industry, and the increasingly complex environment faced by human beings, people have higher and higher requirements for the quantity and performance of building materials. In life, there are various radiation rays around us, such as: radio waves, microwaves, alpha rays, beta rays, etc. Therefore, the preparation of a radiation-resistant mortar plays an important role in industrial, agricultural, and medical radiation-resistant projects. However, in the existing anti-radiation materials, most of them are used to shield α, β, γ, X rays and neutron radiation, and are limited to special occasions such as medical treatment. There are fewer considerations for the shielding of rad...
