Description
Technical field
The present invention relates to a kind of clinker and preparation method thereof, belong to clinker production technical field.
Background technology
In recent years, the exploitation of marine resources is all attached great importance in countries in the world, China harbour, seawall, coast protection, over strait big
The marine engineering such as bridge, refueling at-sea station development is quickly.It is well known that ocean engineering concrete structures are for a long time by salt in seawater
Chemical attack, particularly Cl- corrosion, also by alluvion etc., environment very severe, therefore the endurance issues of extra large work concrete get over
It is taken seriously to get over.Current China mainly uses ordinary cement and a small amount of sulfate resistance in harbour, harbour, ocean engineering
Cement.The impermeability of this kind of cement, wearability are poor, and its resistant to sea water corrodes, sea water resistance washes away can not expire completely with freeze-thaw resistance
The particular/special requirement of sufficient ocean engineering, so that causing that construction quality is high, service life is shorter, brings larger to national economy
Loss.
In the prior art, such as Publication No. CN101343150, CN101659535, CN101445351 patents of invention are public
The cement for construction in sea opened, mainly based on portland cement, high additive slag and flyash, though it is high to possess later strength, corrosion resistant
The characteristics of corrosion is good, but have the disadvantage that early strength is low, although later stage research is by the granular technology using composition material and again
Conjunction technology, inside mixes specific inorganic coagulation material, excites " lateral reactivity " in gelating material, overcomes high additive cement in early days
The shortcoming of low intensity, retains that later strength is high, good corrosion resistance advantage, but current extra large work portland cement resisting chloride ion penetration
Permeability and sulphate-corrosion resistance, are still unable to reach the requirement for using for a long time.
Such as Publication No. CN101224968, the patent of invention of entitled " marine durable cement concrete ", patent is disclosed
Concrete formed with Binder Materials, aggregate, water reducer, additive mix by water, the additive includes rosin or paraffin
More than one, and corrosion inhibitor and colophonium pyrolytic polymer, wherein the volume of rosin, paraffin or its mixture is with the Binder Materials
Gross weight meter is 2~8%, and corrosion inhibitor is 1~5%, and colophonium pyrolytic polymer is 0.01~0.04%.The Binder Materials is by cement and mixes
Close material composition, wherein admixture includes miberal powder and flyash, the volume of cement with the gross weight meter of the Binder Materials as 25~
35%, miberal powder is 45~55%, and flyash is 15~20%.
And for example Publication No. CN102584044A, the invention of entitled " sulphoaluminate maritime work cement and preparation method thereof " is special
Profit, cement disclosed in the patent include 50~80 parts of clinker, 8.0~20 parts of anhydrite, 0~30 part of lime stone, slag 0~
30 parts, 0.1~0.5 part of water reducer, 0.001~0.005 part of air entraining agent, 0.1~0.5 part of retarder, 2~5 parts of silica flour.
The patent is the cement for construction in sea based on sulfoaluminate clinker, and its setting time is fast, it is necessary to by a large amount of additional
Agent solves the problems, such as the compatibility with extra material, increased extra cost.
The content of the invention
Present invention seek to address that in the prior art cement for construction in sea exist production cost is high, resistance of chloride ion penetration and sulfate resistance
Not good, highly doped enough the mixing material of aggressivity solves some corrosion resistances, but gel material content is few, poor durability, causes maintenance
A kind of technical problem such as cost is high, there is provided new clinker, is particularly suited for the clinker of ocean engineering, by raw material
Selection and the specific proportion design of raw material, substantially reduce the production cost of clinker, improve making for ocean clinker
Use performance.
In order to realize foregoing invention purpose, technical scheme is as follows：
Clinker, it is characterised in that：Including following raw material by mass percentage：Calcareous material 30~60%, siliceous material
0~25%, aluminum material 10~40%, ferrous material 0~10%, gypsum material 5~20%；The mineral composition of clinker is C4AS:
10%~40%, C2S：25%~40%, C4AF：10%~30%.
In order to the present invention is better achieved, the calcareous material is lime stone.
At least one in the siliceous material low-grade limestone, low-grade bauxite, sandstone, shale, the low product
Silicon content >=3%, silicon content >=17% in the low-grade bauxite in the lime stone of position.
At least one in the aluminium material material position low-grade bauxite, aluminium making residue, aluminium mine tailing, flyash.
The ferrous material is the one kind in high ferro bauxite, scum, slag, sulfate slag.
The gypsum material is at least one in dihydrate gypsum, anhydrite, desulfurated plaster, ardealite, desulfurization ash.
It is a further object to provide the preparation method of clinker, it is characterised in that：Including dispensing and calcining
Two steps, the dispensing refers to, by each raw material is broken, after grinding, to be mixed；It is described calcining refer to will mix raw material in
At a temperature of 1100~1350 DEG C, 10~90min is calcined, the clinker is obtained after cooling.
Beneficial effects of the present invention：
（1）The calcareous material that the present invention passes through selection, siliceous material, aluminum material, ferrous material, gypsum material is raw material,
And special ratios are designed, obtained clinker has following mineral composition：C4AS:10%~40%, C2S：25%~40%, C4AF：10%
~30%, strong mineral calcium sulphoaluminate of a certain amount of morning is wherein contained in the clinker, tricalcium aluminate is not contained, cement can be greatly reduced
Contraction；And entringite can be formed in hydration process, early strength is not only produced, but also hydration process can be made up
The drying shrinkage phenomenon caused after middle overall volume expansion and the hardening of Portland cement system, clinker of the invention is losing layer
Between lower shrinkage is presented after water, to engineer applied without destructiveness；The dicalcium silicate containing higher amount, makes stable long-term strength simultaneously
Increase, aquation slurry is fine and close, it is impervious good；Compared to other clinkers, iron content is low, increased its resistant to sea water erosiveness.
