Abstract

The present invention relates to ultrahigh-strength quick-hardening sulfate cement formed by firing bauxite chamotte, gypsum, limestone and flyash, which belongs to the field of building materials. The present invention is manufactured from 45 to 60% of chamotte, 3 to 10% of gypsum and 31 to 45% of flyash (coal gangue, limestone) which are mixed, milled, calcined, cooled, digested, etc. The present invention has the advantages of high early strength, good leak and freeze resistance, quick hardening, etc.

Description

Super high strength quick hardening sulfaluminous cement
The present invention relates to a kind of superelevation quick hardening sulphoaluminate cement that is fired into by bauxitic clay grog, gypsum, Wingdale, flyash, belong to building material field.
CN1096504 discloses the patent application technology that name is called " ultralight, high temperature resistant, high-strength cement mortar ", it utilizes low calcium-aluminate refractory cements to be gelling material, float pearl and the microballon that add the flyash extract stir and form, have advantages such as high temperature resistant, light capacity, high strength, but in the cement early strength performance, still be weak.
The purpose of this invention is to provide a kind of characteristics such as early strong, high-strength, impervious and resisting erosion of sulfate that have, be applicable to the super high strength quick hardening sulfaluminous cement of subzero temperature construct, slurry anchor, bolting and shotcreting, assembly unit node, geology well cementation, repairing leak stopping.
The present invention has taked following technical scheme:
With anhydrous sulplo-aluminate is the modified sulphur hydrochlorate grog of major ingredient, is equipped with proper amount of gypsum, Wingdale and the flyash low hydraulic cementing materials of the levigate basicity that forms of admixture such as (coal gangues).Its component and content (in 100% weight ratio) are respectively modified sulphur hydrochlorate grog 45～60%, gypsum 3～10%, flyash (coal gangue, Wingdale) 31～45%.Modified sulphur hydrochlorate grog is formed through the broken calcining of proportion design by bauxitic clay, Wingdale, three kinds of raw material of gypsum.Wherein bauxitic clay should be suitable for Al 2O 3Content is at the mineral reserve than higher-grade more than 70%, Wingdale CaO 〉=52%, SiO 2≤ 1%, gypsum SO 3＞38%.
The proportion design of raw material:
The charge calculation formula of raw material comes out according to following release: suppose in the clinker burning process Al in the alumina 2O 3All form C 4A 3S, SlO 2All form β-C 2S, TiO 2Form CT, and Fe 2O 3Form C 2F, establish alumina 100 (butt) then this moment:
Figure 9710130700031
In the formula: Al 2O 3, SiO 2, Fe 2O 3, TiO 2Be percentage composition in the alumina.
CaO is a percentage composition in the Wingdale.
SO 2Be percentage composition in the gypsum.Above-mentioned three data are converted into percentage ratio promptly get raw-meal ingredient.Calculate according to raw-meal ingredient and give birth to, the Chemical Composition of grog and mineral composition are calculated as follows:
In the formula: SlO 2, Al 2O 3, Fe 2O 3, TlO 2Be percentage composition in the grog, can get the each component amount ranges of the invention described above thus.
Production process is for to measure three kinds of raw material respectively, mix and be crushed to less than 20cm, be milled to 0.08mm screening surplus less than 12% by ball mill, even by homogenizing storehouse homogenizing again, send into raw material silo, finish fs work, qualified raw material and kiln tail sedimentation compartment kiln ash are promoted to kiln tail storehouse behind the mixing in proportion and, unload to kiln, through the rotary kiln tilting rotary table by the spiral metering, slowly flow forward, after bituminous coal was dried by preheating in rotary kiln, grinding was blown into the rotary kiln burning to qualified through gas blower, like this, raw material drying, preheating, decompose, burn till, processes such as cooling form with C 4A 3S is the modified sulphur hydrochlorate grog of essential mineral, by fragmentation, finishes subordinate phase work.The modified sulphur hydrochlorate grog that the digestion cooling is good is carried into standby storehouse, with the gypsum that is crushed to certain particle size, Wingdale utilize microcomputer automatic gauge proportioning machine by modified sulphur hydrochlorate grog be 45～60%, after gypsum 3～10%, flyash (coal gangue, Wingdale) 31～45% weight percents carry out accurate proportioning, the input ball mill carry out grinding to specific surface greater than 3800cm 2/ g, the defeated appointment warehouse compartment of choosing, the manufacture of cement whole process is finished in the packing pack.
Advantage of the present invention is:
Early strength performance is higher, frost resistance, impervious good, has fast hard characteristics, is suitable for the building operation under the special environment condition and the needs of extraordinary construction work.
Embodiment:
Above-mentioned three kinds of compositions in weight percentage are respectively:
Modified sulphur hydrochlorate grog 50%, gypsum 7%, flyash (coal gangue, Wingdale) 43% adopt above-mentioned production process to produce can obtain super high strength quick hardening sulfaluminous cement.

Claims (2)

1, a kind of superstrength quick hardening sulphoaluminate cement, make by the hydraulic cementing materials that with the anhydrous sulfate is modified sulphur hydrochlorate grog, gypsum, Wingdale and the levigate low basicity that forms of admixture of major ingredient, it is characterized in that each component is respectively modified sulphur hydrochlorate grog 45～60% in the content of 100% weight ratio, gypsum 3～10%, flyash 31～45%.
2, superstrength quick hardening sulphoaluminate cement according to claim 1 is characterized in that each component weight percent proportioning is, modified sulphur hydrochlorate grog 50%, and gypsum 7%, flyash are 4.3%.
