Problems solved by technology

[0002] Nowadays, the amount of various waste residues produced by industrial sectors such as metallurgy, coal, electric power, and chemical industry is huge. In my country alone, the amount reaches hundreds of millions of tons every year. So far, some industrial waste residues such as slag and fly ash have been used as raw materials for preparing cement. One of the mixed materials has achieved good economic benefits, but the scope of application is still very limited, and many types of industrial waste have not been effectively utilized

Abstract

A Ba-slag cement features that the Ba slag generated in preparing barium salt from barite is used as one of its raw materials. Its advantages are high performance and radiation-resistant effect.

Description

technical field [0001] The invention relates to cement, in particular to a slag mixed material cement. Background technique [0002] Nowadays, the amount of various waste residues produced by industrial sectors such as metallurgy, coal, electric power, and chemical industry is huge. In my country alone, the amount reaches hundreds of millions of tons every year. So far, some industrial waste residues such as slag and fly ash have been used as raw materials for preparing cement. One of the mixed materials has achieved good economic benefits, but the scope of application is still very limited, and many types of industrial waste have not been effectively utilized. For example, the industrial waste generated when barite is used to produce barium salt, that is, barium slag, is one of them. Contents of the invention [0003] The present invention will provide a kind of barium slag cement that utilizes industrial waste slag and ...
