Mud mortar fluidity assay method》(GB/T 2419) determines slurry fluidity, and the slurry ratio of mud is fixed as 0.5.
Under be specific embodiment：
Embodiment 1
Table 1 is that synthetic zeolite (molecular sieve) and a kind of natural foresite (sodalite) go out to alkali-activated carbonatite Binder Materials alkali soluble
Influence.Powder is made up of the slag powders of 80% mine tailing+20% in Binder Materials, and waterglass quality is powder quality 5% (with Na2O
Meter, accounts for the mass percent of mine tailing and slag powders；2.2) modulus is.Zeolite mixes what is be made up of 80% mine tailing and 20% slag powders
In powder, volume is 1%, 3%, 5%.Sample curing condition be standard curing, i.e. 95 ± 5%RH, 20 ± 2 DEG C.
Table 1
From result, unmodified zeolite is due to being inherently rich in sodium ion, therefore it exchanges alkali-activated carbonatite Binder Materials solution
In sodium ion it is limited in one's ability.According to existing result of study, the ion-exchange capacity of zeolite could be released effectively in heated solution
Put.Therefore, to go out rejection ability to the alkali soluble of alkali-activated carbonatite Binder Materials at normal temperatures extremely limited for unmodified zeolite.On the other hand,
The interface weakening region of many zeolite/gels is introduced due to the incorporation of zeolite granular, therefore when zeolite volume is (3%, 5%) higher
Shi Qiangdu declines obvious.
It is pointed out that finding that molecular sieve, foresite have thickening power when the experiment of the present embodiment is carried out.Due to
Molecular sieve has strong water sorption, and a large amount of water are adsorbed by its inner passage after slurry mix, thus in sample solution quantity
Reduce.It is respectively used for infiltration mine tailing, the water of slag particle to tail off, slurry becomes dry thick, and its fluidity is decreased.Work as molecule
When reaching 5%, the fluidity of slurry is reduced to 140mm, have dropped 70mm for sieve, foresite volume, so low fluidity into
Type is caused and had a strong impact on.When volume is more than 5%, slurry is changed into " loose sand shape ", it is impossible to be molded.Therefore evaluate zeolite sodium from
Its influence to slurry service behaviour (mobility) is had to take into account that during sub- exchange capacity, therefore its volume is unsuitable too high, is no more than
5% is advisable.
The above results show, unmodified zeolite is because causing that it is limited that its alkali soluble goes out rejection ability rich in sodium ion, and it is more
Hole and the characteristic that absorbs water can also make slurry fluidity and probe intensity reduction, therefore the treatment such as calcification, full water need to be carried out to it.
Embodiment 2
It can be seen from result according to embodiment 1, want to reach bonding alkali-activated carbonatite gelling material using the ion-exchange capacity of zeolite
The purpose of alkali metal ion in material, it is necessary to by Zeolite modifying be calcium type.
The method of modifying of zeolite is in 25%NH4Ammonium type zeolite is modified as in the boiling solution of Cl, with the zeolite in 2mol/
LCaCl2Ammonium calcium exchange is carried out in hot solution (90 DEG C), ca-form zeolite, dry for standby is finally obtained.
Table 2 is effect of the calcification zeolite to alkali-activated carbonatite Binder Materials alkali leaching retention.Binder Materials proportioning is Binder Materials
Middle powder is made up of the slag powders of 70% mine tailing+30%, and waterglass quality is powder quality 4% (with Na2O is counted, and accounts for mine tailing and ore deposit
The mass percent of ground-slag；2.2) modulus is.Calcification zeolite is mixed in the powder being made up of 70% mine tailing and 30% slag powders, is mixed
Measure is 1%, 3%, 5%.Sample curing condition be standard curing, i.e. 95 ± 5%RH, 20 ± 2 DEG C.
Table 2
It is ca-form zeolite by Zeolite modifying from result, it goes out suppression to the alkali soluble of alkali-activated carbonatite Binder Materials at normal temperatures
Certain effect is formed with, but it is not notable to reduce degree.Its reason is very slow for the speed that zeolite generation calcium sodium under normal temperature is exchanged, moreover
Zeolite is incorporated into the diffusion that residing environment after slurry is not complete liquid phase environment, i.e. ion and receives greatly limitation.
According to above-mentioned experimental result, should also properly increase curing temperature in the condition for mixing modified zeolite with accelerate calcium sodium from
Son is exchanged, so that the alkali soluble for reducing alkali-activated carbonatite Binder Materials to a greater extent goes out.
Embodiment 3
In order to avoid zeolite loose structure water suction to alkali-activated carbonatite Binder Materials intensity, the influence of service behaviour, can in advance by
Its full water.The mode of full water process is：Mode one, will contain scolecite and be placed in 95%RH, and in 20 DEG C of environment, standing time is 8
Hour；Mode two, according to 1g zeolites：Water, the process point 3 completions in 1 hour are shone in the ratio spray of 1g water.Full water zeolite is in tail
Added when ore deposit, slag powders mix with the aqueous solution of exciting agent, slurry is obtained after being sufficiently stirred for, obtained after slurry shaping, maintenance
Sample.
Through the zeolite of water process of satiating, the effect of interior sealing compound can be not only played, and it is also possible to solve alkali-activated carbonatite glue
Strength retraction problem of the gel material in dry environment.Early-stage Study result shows that alkali-activated carbonatite Binder Materials is in maintenance processes
It is extremely sensitive to air humidity.Under the conditions of dry air (≤40%RH), sample can be very because of drying shrinkage caused by water evaporation
Substantially, this will cause the notable retraction of intensity.For example, it is clearly visible small to open wide 28 days surfaces of sample of maintenance in air indoors
Crackle, these crackles are the main causes for causing sample later strength to be reduced to below 40MPa.However, after mixing full water zeolite
Situation is different.
To mix full hydrone sieve sample, curing strength supports intensity to table 3 with sample mark is not mixed in air, standard conditions indoors
Contrast and slurry fluidity contrast.Room air maintenance condition be 30-60%RH, 17-23 DEG C, mark support condition be 95 ±
5%RH, 20 ± 2 DEG C.Powder is made up of the slag powders of 70% mine tailing+30% in Binder Materials, and waterglass quality is powder quality
5% (with Na2O is counted, and accounts for the mass percent of mine tailing and slag powders；2.2) modulus is.Full water zeolite is in mine tailing, slag powders and swashs
The aqueous solution for sending out agent is mixed again when mixing, and incorporation is 3% (dry mass).
Table 3
By result it is recognized that while the early strength of air care sample supports the much lower of sample compared with mark, but air care is tried
The intensity of sample has no retraction, is even very close in the intensity in both later stages.In early stage, the relatively low original of air care probe intensity
Because：(1) the too fast evaporation of moisture, alkali-activated carbonatite reaction is significantly inhibited because of solution deficiency, and correspondingly early strength is relatively low；
(2) because molecular sieve is in water-saturated state, its ratio of mud that sample is undoubtedly increased to the moisture discharged in slurry so that sample is strong
Degree is reduced.But in the later stage, cause there is molten enough all the time in hardenite because water continuously discharges from molecular sieve channels
Liquid, this solution ensures that the components such as silicon, aluminium, calcium dissolve as reaction medium, and then causes that sial polymerisation is persistently carried out,
Correspondingly intensity keeps increasing.When Free water is depleted in the foster sample of mark, and now the moisture in molecular sieve constantly discharges,
Therefore mix molecular sieve sample and remain able to provide enough solution on the contrary, therefore sial polymerisation remains able to be easier to carry out, phase
Its 28 days compression strength of ground are answered to support sample comparable to mark.Above-mentioned this strength development is made just because of the interior sealing compound of molecular sieve
With.
Also known by result in table, be all under the conditions of mark supports, mixed each age strength of full hydrone sieve sample and do not mix
Sample it is almost completely the same；Slurry fluidity is had little to no effect after the full water of molecular sieve, is still up in 3% volume
More than 200cm.Additionally, both full water modes almost have suitable effect, sample not only has suitable fluidity, and
Each age strength is also suitable.
The above results illustrate that full water process can avoid zeolite to alkali-activated carbonatite Binder Materials intensity, the unfavorable shadow of service behaviour
Ring.
Embodiment 4
Because High Temperature Curing can promote sial polymerisation and be conducive to zeolite ion to exchange, according to embodiment 1,2,3
Result is intended taking and the alkali soluble that modified full water zeolite suppresses alkali-activated carbonatite Binder Materials is mixed under the conditions of High Temperature Curing goes out.
In the present embodiment, the volume of modified full water foresite is fixed as 3%.In Binder Materials powder by 80% mine tailing+
20% slag powders are constituted, and waterglass quality is powder quality 4% (with Na2O is counted, and accounts for the mass percent of mine tailing and slag powders；
2.2) modulus is.Modified full water zeolite is mixed again when mine tailing, slag powders mix with the aqueous solution of exciting agent.Sample curing condition
For elder generation in standard conditions (95 ± 5%RH, 20 ± 2 DEG C) maintenance 24 hours, then respectively under the conditions of 40 DEG C, 60 DEG C, 80 DEG C
Maintenance 24 hours, finally continues to conserve to setting age in standard conditions.
Table 4 be High Temperature Curing and mix full water calcification foresite alkali-activated carbonatite Binder Materials alkali soluble is gone out, the influence of intensity.
Table 4
From result, 3% calcification foresite is mixed under the conditions of High Temperature Curing to be had well to the alkali leaching retention of sample
Effect.Compared to the measure for only taking High Temperature Curing, alkali soluble output is lower after mixing zeolite, and this explanation is except High Temperature Curing pair
Outside the inhibitory action that alkali soluble goes out, calcium sodium exchanges the inhibitory action gone out to alkali soluble in also there is modified foresite.The two common
Effect causes the alkali soluble output of alkali-activated carbonatite Binder Materials (conserving for 28 days) to be reduced to 3% or so.Additionally, in High Temperature Curing condition
Under, mixing full water modified zeolite sample equally has early strong and high-strength feature.For example, under conditions of 3% modified full water zeolite,
60 DEG C of 3 days compression strength of maintenance sample can exceed 50MPa, and compression strength can exceed 70MPa within 28 days.
According to this experimental result, the material that is gelled to alkali-activated carbonatite is preferably realized under the conditions of High Temperature Curing using the full water zeolite of calcium type
The suppression that material alkali soluble goes out.
The result of integrated embodiment 1,2,3,4, it is contemplated that the solid caustic soda ability of zeolite, preferably uses containing scolecite, containing scolecite
Can be obtained by sodalite calcification；In view of the water sorption that zeolite is strong, it is preferably weakened to slurry work using the method for pre- full water
Make the adverse effect of performance；In view of calcium sodium replacement rate, preferably use High Temperature Curing condition to accelerate calcium sodium to replace；In view of boiling
The interface weakening region being likely to form between stone/gel, the volume of zeolite should be no more than 5%.
The not most part of the present patent application, those skilled in the art can on demand select according to existing knowledge, such as how will
Raw material mixes, and selects suitable curing condition etc., will not be repeated here.
Above example is only exemplary embodiment of the invention, is not used in the limitation present invention, protection scope of the present invention
It is defined by the claims.Those skilled in the art can make respectively in essence of the invention and protection domain to the present invention
