Description
Technical field
The present invention relates to building block, a kind of beneficiation tailing being made using discarded mine tailing, abandoned mine for main material is referred in particular to
Concrete segment is made.
Background technology
China is 1,300,000,000 populous nations, and soil qualifications and record of service source is deficient.And China's clay solid brick still accounts for materials for wall total yield at present
Nearly the 80% of amount, high energy consumption, ruins that the problems such as field, pollution is extremely serious, and field is ruined in the clay resource of each 2,200,000,000 tons of consumption, brickmaking
About 120,000 mu, consume energy 82,000,000 tons of mark coals, while discharging substantial amounts of dust and carbon dioxide.Therefore, Development of Novel wall material
Material is related to the implementation of China's strategy of sustainable development, while being also related to the sound development of building materials industry.
With the fast development of national economy and deeply implementing for national industrial policies, building materials industry is also faced with a great knot
Structure is adjusted, and implements the reform of building energy conservation and materials for wall, some old, small scales, seriously polluted, high energy consumption, resource wave
The building materials enterprise of expense type subsequently enters ranks that are superseded, closing.This is national from protection soil, environmental protection, the saving energy
Fundamental state policy is set out, the Implement of sustainable development strategy, promotes the important measure of modernization construction, there is very important reality meaning
Adopted and far-reaching historic significance.
China is a mineral resources production and consumption big country.But the characteristics of due to Mineral Resources in China be single large ore deposit it is few,
Association and poor mine disaster ore dressing is more, the natural grade of ore is more low altogether, adds the reasons such as selecting and purchasing technology, process technology and equipment backwardness,
Mineral resource recovery rate is low, the discarded object yield of unit mineral products is big, the problems such as causing China's available inadequate resource, institute
Seem very necessary and urgent with the utilization of resource of tailings.
Mine tailing is that mining firm discharges " discarded object " under certain condition of technology and economy, but is again simultaneously potential secondary resource,
It is that can carry out effective exploitation again completely when technology, economic condition allow.The long-term stacking of mill tailings：Take big
Measure soil；Have a strong impact on ecological environment；Tailings Dam extremely easily produces potential safety hazard, and granularity attenuates after ore is handled through ore dressing,
Surface area increases, leakage of easily flowing and collapse when storing up, and causes the natural calamities such as vegetation deterioration, especially rainy season or earthquake easily to cause
Landslide or mud-rock flow, bring about great losses.In the recent period, with the progress of science and technology, mine tailing is as a kind of resource gradually by people
Receive, and greater advance has been obtained to the comprehensive utilization of mine tailing, particularly utilized in the mass efficient of building material industry in recent years
As a kind of trend.As can be seen here, comprehensively utilize mill tailings, can effectively mitigate tailings discharging pollution on the environment and
Harm.
The content of the invention
The purpose of the present invention is to be improved and innovated for shortcoming present in background technology and problem effectively to utilize there is provided a kind of
Concrete segment is made in the beneficiation tailing that mine discarded tailing is made.
The present invention is made from the following raw materials in parts by weight：
40-60 parts of iron rejects, 40-60 parts of iron debris, 8-15 parts of cement, 15-30 parts of coarse sand granule, appropriate amount of water.
The preparation method of building block of the present invention comprises the following steps：
1st, minus 200 mesh iron rejects is prepared, it is standby.
2nd, by iron debris crusher in crushing into 9mm or so material, it is standby.
3rd, the material and cement, coarse sand granule got 1,2 steps ready add appropriate water by mixing plant is put into after institute's expense metering
Mixing and stirring.
4th, solid block is made finally by former die cast, and through natural curing, stacking, semi-finished product stacking, surface layer
Polishing deep processing, finished product stack, examine and dispatch from the factory.
The optimum amount parts by weight of each raw material of building block of the present invention are：
50 parts of iron rejects, 50 parts of iron debris, 10 parts of cement, 25 parts of coarse sand granule, appropriate amount of water.
Preparation process of the present invention is carried out at normal temperatures substantially.
Die cast process temperature control of the present invention is at 20-30 DEG C.
Advantages of the present invention and beneficial effect：
Major ingredient of the present invention uses mine tailing iron rejects and iron debris, realizes twice laid, solves discarded tailing pollution.
Also solve destruction of original common brick to land resource and environment simultaneously.The present invention is that national construction industry prohibits the use of conventional clay
In the case of, the novel wall construction material arisen at the historic moment.Have the advantages that it is high from heavy and light, intensity, production and using mine tailing mix
Solidifying earth building blocks can accomplish energy-conservation, save land, economize on water, profit it is useless, build effective usable floor area increase, the tradition such as construction period shortens
The incomparable superiority of clay brick, becomes the preferred material for replacing solid clay brick comprehensively, by national industrial policies
Support energetically.Possess that lightweight, thermal and insulating performance is good, intensity is high by the mill tailings building block product produced of the present invention,
Anti-seismic performance is good, good processability, with certain heat-resisting quantity, sound insulation value is good, be conducive to the premium properties such as mechanized construction.
