Abstract

The invention relates to anti-electromagnetic radiation dry-mixed mortar using barium slag. The dry-mixed mortar is prepared by mixing the following raw materials in parts by weight: 40 to 55 parts ofsolid solution, 15 to 25 parts of iron tailings, 20 to 38 parts of gypsum, 0.2 to 0.5 part of cellulose ether, 0.1-1.5 parts of silicon carbide fibrous crystal, 0.05 to 0.6 part of foaming agent, 0.2to 1 part of graphite, and 0.04 to 0.06 part of retarder, wherein the total amount of all the components satisfies 98 to 102 parts, and the solid solution is prepared by mixing iron tailings, bariumslag and boric oxide in a mass ratio of (1-1.4):(6-6.6):(0.012-0.02). The anti-electromagnetic radiation dry-mixed mortar using barium slag provided by the invention has good radiation resistance andexcellent mechanical properties, can be widely applied to industrial and medical radiation-resistant engineering, and uses industrial waste to bring benefits to the 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...
