无害化钡渣用于水泥混合材的研究

Study on Harmless Barium Slag Used in Cement Admixture

钡渣是用重晶石生产碳酸钡过程中排放出的固体废弃物,文中以经过硫酸亚铁和硫酸钠复合沉淀法处理过的无害化钡渣为研究对象,探究其在不同掺入量下制备的水泥力学性能,得到无害化钡渣的最大安全掺入量。

Barium slag is a solid waste discharged from the production of barium carbonate from barite.The research object of this paper is harmless barium slag treated by FeSO4 and Na,SO4 composite precipitation method,the maximum safe content of harmless barium slag was obtained by studying the mechanical properties of cement prepared with different content of barium slag.
