Description

technical field [0001] The invention relates to the technical field of building composite materials, in particular to an electromagnetic shielding cement-based composite material and a preparation method thereof. Background technique [0002] Titanium slag is a kind of granular or massive waste slag obtained after quenching or natural cooling of the slag discharged from the process of smelting vanadium-titanium magnetite in the blast furnace. It is currently difficult to use because of its high content of titanium dioxide and poor grindability. One of the wastes, compared with ordinary slag, because high-titanium slag has the above particularities, it has not been developed and utilized on a large scale. A large amount of waste slag not only wastes resources, occupies cultivated land, but also pollutes the environment. Therefore, the study of titanium slag is of great economic importance. and social significance. [0003] With the rapid increase of electronic devices and eq...
