Description
Technical field
The invention belongs to technical field of concrete production, be specifically related to a kind of concrete utilizing tower mountain mine tailing to produce.
Background technology
The countries that at present many industry are flourishing have developed the fresh target as mine development, tail using mining waste
The comprehensive utilization in ore deposit and the degree of improvement are as weighing a national science and technology level and the mark of economic development level.
Abroad carrying out Tailings utilization research relatively early, state's tailings glass technology such as the U.S., Russia, Canada is the most ripe,
Tailings glass rate is higher, and the recycling of iron mine tailings has caused the attention of every country, the iron mine tail of some developed countries
Slag recovery utilization rate has reached more than 60%, has even accomplished to stack mine without mine tailing.External practice have shown that, by ore deposit the most for many years
Mountain mine tailing carries out whole development utilization as complex mineral raw material, is just becoming economical and practical new mineral resources.It not only can make
Originally the mine of resource exhaustion or inadequate resource becomes the recovery of new resources base again and extension produces, and can open up green wood
The sciemtifec and technical sphere of material, promotes scientific and technological progress, can also solve environmental pollution simultaneously, improves the ecological environment and renovate territory.At present
Domestic iron ore mine output capacity averagely up to more than 70%, according to statistics, within 2000-2009 years, iron mine tailings is discharged in the whole nation altogether
28.32 hundred million tons, account for the 45% of all metal tailings.Iron tailings comprehensive utilization ratio is only 14%, and the utilization rate of iron tailings is the most more
Low.
In the tower mountain village of Linfen, Shanxi Province, in the past due to a large amount of exploitated ores, a large amount of discarded mine tailing building stones heaps
Amassing in gully, pile up like a mountain, dug dead meal mountain under for it with private due to neighbouring villager later, cause mine tailing stone due to
Load-bearing is unbalance, there occurs building stones landslide accident, causes and just works under mountain and movable over one hundred people death, but also makes to work as
The governor in the Meng of former Shanxi vice-governor is punished by relevant department, and this accident causes the most serious shadow socially
Ring.Owing to tower mountain mine tailing stone containing substantial amounts of mineralogical composition, the performance of concrete there is improvement greatly.The present invention is just
More preferable to twice laid and production performance concrete is proposed.
Summary of the invention
It is an object of the invention to provide a kind of concrete utilizing tower mountain mine tailing to produce.The present invention not only increases mixed
The erosion of the sulfate resistance of solidifying soil, improves the durability of concrete, and improves the performance of concrete mix, improve
The intensity of concrete, energy-conserving and environment-protective.
The technical solution used in the present invention: utilize the concrete that tower mountain mine tailing produces, it is characterised in that by following weight
