Description
Technical field
The invention belongs to building material technical fields, and in particular to a kind of high-activity mineral blending material and preparation method thereof.
Background technique
Along with China's rapid economic development, metal smelt industry is flourishing, and metal smelt process will necessarily
Generate a large amount of melting waste slag.Ferronickel slag is the fourth-largest industrial residue in current China, and major part waste residue is mainly used for well at present
Lower filling, utilization rate are very low.In face of the bulk deposition of steel slag and ferronickel slag, government department is faced with severe environmental protection pressure, and
Smelting enterprise is then unable to get the development of continuous and effective.
Currently, granulated blast-furnace slag is widely used, ground granulated blast furnace slag gradually shows that supply falls short of demand, price
Also Continued.However granulated blast-furnace ferronickel slag is not still utilized effectively but, this is mainly due to granulated blast-furnace ferronickels
The 28d activity of slag is lower, is unable to satisfy application requirement.Currently, the 28d activity of ground granulated blast furnace slag reaches 95% or more, and grain
Change blast furnace ferronickel slag by improve granulated blast-furnace ferronickel slag mill efficiency and finished particle distribution after, 28d activity reach 85% with
On, but still it is lower than 95%.
The chemical component of granulated blast-furnace ferronickel slag and granulated blast-furnace slag is shown in Table 1.
1 chemical component table of table
It can be calculated from table 1, the alkaline coefficient of granulated blast-furnace ferronickel slag and granulated blast-furnace slag is respectively 0.68 and 0.96,
Quality coefficient is respectively 1.68 and 1.89, and the alkaline coefficient and quality coefficient of granulated blast-furnace ferronickel slag are below granulated blast-furnace mine
Slag, in addition the grindability of granulated blast-furnace ferronickel slag is also below granulated blast-furnace slag, and it is poly- that packet pelletizing is easily generated in grinding process
Phenomenon influences mill efficiency and finish fineness.In similar specific surface, the 28d activity of granulated blast-furnace ferronickel ground-slag less than
85%, and the 28d activity of ground granulated blast furnace slag reaches 100%, performance test results are as shown in table 2.
2 physical property testing result of table
Therefore, if can improve the 28d activity of granulated blast-furnace ferronickel ground-slag to 95% or more, it not only can satisfy construction
The market demand, while can largely consume granulated blast-furnace ferronickel slag, this by for the resource utilization of granulated blast-furnace ferronickel slag and its
It plays a positive role to appropriation of land and to the pollution of environment.
