Description
Technical field
The invention belongs to building material technical field, and in particular to a kind of building clinker and preparation method thereof.
Background technology
The production of common brick and use, in existing more than the 3000 year history of China.Now, the wall used in construction project
In body material, common brick is still occupied an leading position.Although there is many deficiencies in common brick, due to cheap, work
Skill is simple, design and construction technique is ripe and the reason such as the use inertia of people, and common brick is when considerably long from now on
In, particularly in rural area, remain one of main materials for wall.
The existing certain intensity of sintered common clay brick, has preferably heat-insulated, sound insulation property again, and winter indoor wall will not
There is dew condensation phenomenon, and cheap.Although various new materials for walls continuously emerge, fired brick is in a period of time from now on
Interior, still can be used in masonry project as a kind of main material.
Clay be containing the grains of sand seldom, have the soil of stickiness, moisture is not easy to pass therethrough just with preferable plasticity.One
As clay all by being formed after silicate mineral at the earth's surface weathering.Typically in situ weathering, particle is larger to form tap closely
Stone originally, referred to as primary clay or primary clay.The composition of this clay is mainly silica and is glued with aluminum oxide
Typically contain in soil：Kaolinite (Al2O3·2SiO2·2H2O), mountain tallow (Al2[(OH)4Si2O5]·nH2O), allophane
(Al2O3·SiO2·2,5H2O) etc..
China is electrolytic manganese producing country maximum in the world at present, and electrolytic manganese yield accounts for the 98% of Gross World Product.I
The manganese resource of state is mainly the manganese spar based on manganese carbonate ore, produces manganese metal using electrolysis sulfuric acid preparation of manganese, is obtaining
Also substantial amounts of acid slag manganese slag is generated while obtaining manganese metal.Due to indiscriminate mining and serious waste in recent years to manganese resource, make
The increasingly reduction for having become manganese ore to sample, now often produces the manganese slag that 1 ton of manganese metal will produce 8～9 tons.Due to a lack of effectively sharp again
With technology, these substantial amounts of manganese slags mainly with stack or landfill in the form of processed, the industrial manganese slag that stacks year by year is to ring
Border causes severe contamination, be mainly shown as in manganese slag contain a large amount of ammonia nitrogens, sulfate, heavy metal ion for example cadmium, lead, arsenic,
Pollution and destruction that copper, zinc and manganese etc. are caused to air, earth's surface/underground water source, soil texture, ecological environment etc. near slag field,
Become the principal element of restriction China electrolytic manganese industry sustainable development.If added through certain process and other batch mixings
Plus, it is possible to achieve effective recovery of manganese slag is utilized with comprehensive resource, so as to reduce the pollution to environment, produces good economy
Benefit and environmental benefit.
Tongren district Guizhou Province area manganese resource enriches, and is one of main manganese ore production base in Guizhou Province, and its manganese ore mainly divides
In big dragon, Song Tao, Shiqian, Dejiang also have a small amount of distribution to cloth.In recent years, locality also brings a large amount of while manganese industry is developed
Manganese slag, causes the ecological severe contamination with environment.Currently, people have been carried out widely with recycling to the recovery of manganese slag
Research, such as extracts manganese metal from manganese slag, is used as cement retarder, production ash bricks and concrete, prepares Ceramic Tiles, make honeybee
Socket type coal fuel, production manganese fertilizer, production glaze or microcrystal glass material, it is used as building materials or roadbed material etc., these methods are
The comprehensive utilization of manganese slag opens new approaches.
According to the mineral composition analysis to electrolytic manganese residues, electrolytic manganese residues are mainly containing calcium sulphate dihydrate and quartz, its chemical group
Become then and be mainly Cao, MgO, Al2O3、SiO2Deng, therefore with produce ordinary fired brick clay as primary raw material, existing general
It is common to prepare that a certain proportion of trade waste electrolytic manganese residues or other raw materials is properly added in the green compact of logical clay brick
Clay brick is completely worth exploration and feasible, and this contributes to improving the performance structure of former common brick and expands industry
Manganese slag is in the new way of building material field application.
Content of the invention
In view of this, which is combined with clay, there is provided a kind of by the present invention for the problem of the reality harm of electrolytic manganese residues
Building clinker and preparation method thereof.
In order to solve above-mentioned technical problem, the invention discloses a kind of building clinker, according to mass percent by with
Lower raw material composition：Clay 80～90%, electrolytic manganese residues 5～15%, coal dust 5%, above each constituent mass percentage sum is
100%.
The preparation method of above-mentioned building clinker, specifically implements according to following steps：
Step 1, respectively manganese slag, clay, coal are smash etc. after coagula is smashed to pieces dry at 80～90 DEG C 24～26h remove former
Then Free water in material is crossed 120 mesh sieves and respectively obtains manganese ground-slag, clay powder, coal dust to constant weight after ball milling；
Step 2, weighs clay 80～90%, electrolytic manganese residues 5～15%, coal dust 5% by mass percentage respectively, above each
Constituent mass percentage sum is 100%；
Step 3, the clay that step 2 is weighed, electrolytic manganese residues and coal dust mixing after under 15～20MPa pressure pressurize 60s
Compressing, sintering is eventually passed, obtains building clinker.
Wherein, sintering is first warming up to 100 DEG C from 20 DEG C with the heating rate of 5 DEG C/min and is incubated 30min, then heats to
500 DEG C and be incubated 30min, be warming up to 800 DEG C again and be incubated 60min, then heat to 1060 DEG C and be incubated 180min, finally with
Stove is cooled down and obtains building clinker.
Compared with prior art, the present invention can be obtained including following technique effect：
(1) the raw materials used cheap, species of the present invention is few, and the present invention is raw materials used only three kinds, is respectively provided with cheap, easy buying
Advantage.
(2) primary raw material of the present invention is clay, and source is wide, and its early stage treatment process is few and simple, and utilization is big,
Mass fraction in formula is up to 80～90%.
(3) turn waste into wealth, resource reutilization.Electrolytic manganese residues are industrial residue, and discharge capacity is big, seriously polluted, makes to environment
Become high risks, the present invention as be properly added raw material be added in clay by a certain percentage and prepare unselected clay sintering
Brick, the resource that can achieve trade waste are recycled, and are that the recycling problem of electrolytic manganese residues provides a kind of new way
Footpath.
(4) building clinker of the present invention, by adding electrolytic manganese residues and coal dust so that the fired brick of preparation in clay
Intensity reach the fired brick national standard of MU25, can be applied in the building with certain resistance to compression, rupture strength requirement completely
Material Field.
Certainly, the arbitrary product for implementing the present invention is it is not absolutely required to while reaching all the above technique effect.
