激发水淬锰渣与钢渣的活性用作细掺料砂浆的试验研究

Study on Activated Water-granulation Manganese Slag and Steel Slag Used as Fine Mortar Mixture

对广西冶金行业排放的大量水淬锰渣、钢渣开展了用作细掺料砂浆的研究。经对锰渣、钢渣的基本性质分析发现,锰渣活性指数仅为70%～80%,活性偏低,必须对活性进行激发。研究表明,以石膏、石灰自制的激发剂为活性激发剂,并掺入磨细粉煤灰,可有效提高渣料的活性指数。通过试验确定了激发剂与基础配料的较优工艺条件,并通过分别粉磨制备了活性矿物细掺料—锰渣矿粉。

A great deal of water-granulation manganese slag and steel slag discharged by Guangxi metallurgy industry is studied to be used as fine mortar mixture.Through analysis of the basic properties of manganese slag and steel slag,it is found that activity index of manganese slag is only 70 %~80 %,lower than the standard,so it must be activated.It is shown from research that the activator prepared by gypsum and lime mixed with fine flyash can effectively improve activity index of slag.The optimum process condition of activator and basic mixture is determined through test.Activated mineral fine mixture,i.e.manganese slag is prepared by separately grinding.
