Abstract
The invention discloses a kind of method for burning till belite aluminium sulfate sulphur ferrous aluminate sulphur calcium silicate cement clinker, comprise the following steps：Step a, industrial residue is mixed with industrial gypsum, is 0.3~0.5 to add water mixing by the ratio of mud, is poured into slurry in mould after 15~60min of grinding, the demoulding, obtains sample after shaping.Step b, by said sample thermostatic curing, curing temperature is 60~150 DEG C, and curing time is 3~9h；80~130 DEG C of curing temperature in the step b, curing time is 3~6h.Step c, then at 60~120min is calcined at 800~1150 DEG C, the sample after calcining is taken out from high temperature furnace, rapid cooling；Product is obtained after grinding.Calcination condition is preferred：Calcining heat is 1050 DEG C, calcination time 120min.The present invention will not produce substantial amounts of carbon dioxide without using lime stone, increase environmental pressure, another aspect calcining heat is low, and then energy consumption is low.Therefore the present invention is a kind of low-carbon, the preparation method of green.
Description
Technical field
The invention belongs to field of material technology, and in particular to a kind of easy fired belite-aluminium sulfate-sulphur iron aluminium
The preparation method and its product of hydrochlorate-sulphur calcium silicate cement clinker.
Background technology
The world today is developed rapidly, and people become more concerned with us and rely while material life is improved
The earth of existence, as construction material --- the cement that consumption is maximum, rises emphatically to progress of human society and socio-economic development
While acting on, the high energy and resource consumption and greenhouse gas emission, usual normal portland cement, oxidation are also generated
Calcium content is about 66%, and about 1450 DEG C of the formation temperature of 50~70% alite mineral, i.e. tricalcium silicate is accounted in clinker.Should
Mineral contain calcium oxide up to 73.7%, CaCO3Power consumption accounts for the theoretical heat consumption of clinker 46% or so is decomposed, causes common portland cement
The high energy consumption of sinter leaching；Belite mineral, i.e. dicalcium silicate, temperature be higher than 1250 DEG C at can quickly be formed, therefore can compared with
Formed under low kiln temperature, in addition, belite is 65.1% containing CaO, the CaO content less than in alite 73.7%, then institute
Lime stone amount is needed to reduce, caused energy expenditure and carbon emission are also accordingly reduced therefrom, and early hydration speed is low；Anhydrous sulphur aluminium
Hydrochlorate mineral (3CaO3SiO2·CaSO4), CaO content low (36.8%) and to form temperature low (1300 DEG C) in composition, and with
C2S-sample has energy-conservation and low CO2The characteristics of discharge, and the mineral have the characteristics of improving early strong, due toCrystal structure
In there are multiple ducts, mineral have larger solid solution capacity, and aluminium can be replaced to form sulphur ferrous aluminate by iron, it is possible to decrease aluminum-containing mineral
Usage amount, in order to reduce energy resource consumption in cement production process and carbon dioxide discharge, start both at home and abroad
Research to low aluminium or high silicon sulphate aluminium cement.
In recent years, people have studied calcium ion in calcium sulphoaluminate and be replaced by barium and strontium ion, and what aluminium was replaced by iron ion
Research is very few, and the formation of sulphur calcium aluminoferrite is general more than 1200 DEG C.The existing method for preparing sulphur calcium silicates, such as application number
For 201510066039.8 Chinese patent application, a kind of sulphate aluminium cement is disclosed, its calcining heat and guarantor according to setting
The warm time need to carry out secondary clacining；The Chinese patent application of Application No. 201510066040.0, discloses a kind of sulphur calcium silicates
Preparation method, calcining heat be 1100~1250 DEG C, be incubated 2~8h.It is secondary that there is aforesaid way following not enough (1) need to carry out
Calcining, program is complicated, and calcining heat is high first；(2) soaking time is long needed for, and energy resource consumption is big.One kind can be developed once
The cement containing sulphur calcium silicates and sulphur ferrous aluminate of low temperature synthesis, can not only overcome above-mentioned technique of the prior art to answer
Miscellaneous, high energy consumption deficiency, and effective processing of waste residue can be realized, it is to be worth the problem of this area research.
The content of the invention
Goal of the invention：Easy fired belite-aluminium sulfate-sulphur iron aluminic acid-sulphur the calcium silicate cement of the present invention is ripe
Material, solves the environmental problem that the high energy consumption in existing cement production process and industrial residue accumulation are caused.
Technical scheme：It is of the present invention to burn till belite-aluminium sulfate-sulphur ferrous aluminate-sulphur calcium silicate cement clinker
Method, comprise the following steps：
Step a, industrial residue is mixed with industrial gypsum, is 0.3~0.5 to add water mixing by the ratio of mud, grind 15~
Slurry is poured into mould after 60min, is stripped after shaping, obtains sample.
Step b, by said sample thermostatic curing, curing temperature is 60~150 DEG C, and curing time is 3~9h；The step
80~130 DEG C of curing temperature in b, curing time is 3~6h.
Step c, then at 60~120min is calcined at 800~1150 DEG C, the sample after calcining is taken out from high temperature furnace,
Rapid cooling；Product is obtained after grinding.Calcination condition is preferred：Calcining heat is 1050 DEG C, calcination time 120min.
The present invention also has a kind of alternative solution, is：Described step a, step b are replaced with：By industrial residue, industry
Gypsum is mixed with waste material containing hydrated product, is added water mixing by 0.1~0.2, is well mixed shaping, is obtained sample, then subsequent steps
c。
Specifically, for above two scheme, described industrial gypsum is desulfurated plaster or ardealite.
Described industrial residue includes sa raw material, calcareous raw material, ferriferous raw material, iron aluminum raw material；Wherein sa
Raw material is gangue；Aluminum raw material is mine tailing bauxite；Calcareous raw material is carbide slag, lime dewatered sludge；Ferriferous raw material is sulphur
Iron ore slag；Iron aluminum raw material is red mud.
Described waste material containing hydrated product is silico-calcium aluminum raw material, such as residual slurry of tubular pile and discarded concrete fines.
More specifically, the proportioning of raw material is in above-mentioned steps：Sa raw material or silicon calcareous raw material：Iron aluminum raw material：Aluminium
Matter raw material：Industrial gypsum：Calcareous raw material=9.74~20.69%：4.35~4.99%：27.88~41.77%：9.43~
