Description
Technical field
The invention belongs to field of material technology, it is related to a kind of preparation method of belite-calcium sulphoaluminate-sulphur calcium silicate cement
And its product, and in particular to the method and its product of a kind of easy fired belite-calcium sulphoaluminate-sulphur calcium silicate cement.
Background technology
The world today develops rapidly, and people become more concerned with us and rely while material life is improved
The earth of existence, as construction material-cement that consumption is maximum, plays important to progress of human society and socio-economic development
While effect, the energy high and resource consumption and greenhouse gas emission, usual normal portland cement, calcium oxide are also generated
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.The ore deposit
Thing is containing calcium oxide up to 73.7%, CaCO3Power consumption accounts for clinker theory heat consumption 46% or so is decomposed, causes common portland cement ripe
The high energy consumption that material burns till；Belite mineral, i.e. dicalcium silicate, temperature can be formed quickly higher than at 1250 DEG C, therefore can be relatively low
Kiln temperature under formed, additionally, belite containing CaO be 65.1%, the CaO content less than in alite 73.7% is then required
Lime stone amount is reduced, and the energy ezpenditure and carbon emission for causing therefrom are also accordingly reduced, and early hydration speed is low；Anhydrous sulphur aluminic acid
Calcium mineral (3CaO3SiO2·CaSO4), CaO content low (36.8%) and formation temperature are 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, aquation have " two is small, in
Between it is big " feature, 0~6h of aquation initial stage, hydration reaction is slower, and AFt contents are low, and mid-term 6h~3d, hydration rate is most fast, big absolutely
Partial hydration reaction all concentrates on stage completion, and 3~28d of latter stage, calcium sulphoaluminate continues to react, but speed significantly subtracts
Slow, sulphur calcium silicates, also known as special western nit, is considered as always inert material, but actually a kind of active material, generally 950
~1200 DEG C can form, aquation second day just can rapid aquation generation entringite, in order in reducing cement production process
Energy resource consumption and carbon dioxide are discharged, the research started both at home and abroad to low aluminium or silicon sulphate aluminium cement high.
The existing method for preparing sulphur calcium silicates, such as Chinese patent application of Application No. 201510066039.8, it is open
A kind of sulphate aluminium cement, it need to carry out secondary clacining according to the calcining heat and soaking time of setting；Application No.
201510066040.0 Chinese patent application, discloses a kind of preparation method of sulphur calcium silicates, and calcining heat is 1100~
1250 DEG C, it is incubated 2~8h.There is aforesaid way following deficiency (1) need to carry out secondary clacining, and program is complicated, and calcines temperature first
Degree is high；(2) soaking time is long needed for, and energy resource consumption is big.A kind of water containing sulphur calcium silicates of low temperature synthesis can be developed
Mud, can not only overcome the shortcomings of above-mentioned complex process of the prior art, high energy consumption, and can realize effective place of waste residue
Reason, is the problem for being worth this area research.
The content of the invention
Goal of the invention：Sulfur-bearing calcium silicate cement complex process, the deficiency of high energy consumption are prepared for existing, can in order to meet
The requirement of sustainable development, the invention provides a kind of method of easy fired belite-calcium sulphoaluminate-sulphur calcium silicate cement
And its product, the method only need to calcine once, and soaking time is short, and calcining heat is low, and realizes the comprehensive utilization of discarded object
Technical scheme：The method of easy fired belite-calcium sulphoaluminate-sulphur calcium silicate cement of the present invention,
Comprise the following steps：
Step a, industrial residue is mixed with industrial gypsum, is added water mixing for 0.3~0.41 by the ratio of mud, and grinding 15~
Slurry is poured into mould after 60min, the demoulding after shaping obtains sample.
Step b, by said sample thermostatic curing, curing temperature is 60~150 DEG C, and curing time is 3~9h；It is preferred that conserving
80~130 DEG C of temperature, curing time is 3~4h.
Step c, then at 60~120min is calcined at 750~1150 DEG C, the sample after calcining is taken out from high temperature furnace,
Rapid cooling；Product is obtained after grinding.Preferred calcination temperature 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 mixes with waste material containing hydrated product, is added water mixing by 0.1~0.2, is well mixed shaping, obtains 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, aluminum raw material, calcareous raw material；Wherein sa raw material is increasing calcium liquid
State slag, gangue；Aluminum raw material is mine tailing bauxite；Calcareous raw material is carbide slag, sugared filter mud or lime dewatered sludge.
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 the raw material in above-mentioned steps is：Sa raw material or silicon calcareous raw material：Aluminum raw material：Work
Industry gypsum：Calcareous raw material=10.77~54.12%：5.67~30.97%：5.95~15.28%：18.73~61.26%.
Grinding in above-mentioned steps, is milled to specific surface area for 350~420m2/kg。
Found in research, hydro-thermal presoma of the present invention is larger to the Effect on Mechanical Properties of cement products, this hair
Bright described hydro-thermal reaction is that the sample after the demoulding is carried out into thermostatic curing, and optimal curing condition is：Curing temperature 80~130
DEG C, curing time is 3~4h.Optimal calcination condition is：Calcining heat is 1050 DEG C, calcination time 120min.
The product prepared using herein described preparation method, C is contained in the product2S：33~62%；
30~42%；8~25%.
Beneficial effect：The method of easy fired belite-aluminium sulfate-sulphur calcium silicate cement of the invention is by closing
