Description
Technical field
The invention belongs to building material technical field, especially relate to a kind of Binder Materials with flyash as raw material and
Preparation method.
Background technology
Architectural engineering needs substantial amounts of Binder Materials, wherein consumption maximum for all kinds of cement.The production of cement to disappear
Consume the substantial amounts of energy and the non-renewable resources such as lime stone, clay, discharge a large amount of greenhouse gases simultaneously and pollute environment.Utilize industry
Discarded object is primary raw material, develops energy consumption and depletion of non-renewable resources is few, effect on environment is little, can substitute or part substitutes
The Binder Materials of cement has important economy, resource and environmental protection and is worth.Flyash is mainly to be discharged by thermal power plant
The solid waste gone out, the flyash that power plant's dry method is discharged in recent years is utilized by building and building material industry the most,
But still having the flyash of a large amount of wet method discharge over the years, owing to its general granularity is relatively thick, phosphorus content is higher, its physical property and reaction
Activity can not meet the requirement as cement mixture and concrete admixture, it is impossible to is directly applied to cement and coagulation in large quantities
In soil, therefore stored up for a long time and fail effectively to utilize.These flyash store up land occupation, pollute surrounding environment, it would be highly desirable to
Dispose.Utilize flyash to prepare Binder Materials for primary raw material, can save non-renewable resources, and energy-saving and environmental protection.But it is existing
Useful coal ash for manufacturing exists for the technology of Binder Materials that flyash consumption is few, quality of fly ash requiring, height and properties of product are poor
Problem.
Summary of the invention
The present invention is directed to the deficiencies in the prior art, it is provided that a kind of Binder Materials with flyash as raw material and preparation side thereof
Method, this Binder Materials can be with rapid solidification, long-term strength height.
The present invention is by the following technical solutions:
A kind of Binder Materials with flyash as raw material, including the grog 92 of weight portion meter～95 parts, gypsum 5～8 parts and
Retarder 0.2～1.5 parts；The raw material of described grog includes flyash 62～78 parts, lime 22～38 parts of weight portion meter, swashs
Send out agent 0.5～2 parts and water 150～250 parts.
As preferably, described exciting agent is alkali metal hydroxide or alkali carbonate.
As preferably, described gypsum is at least one in dihydrate gypsum, semi-hydrated gypsum, anhydrous gypsum.
As preferably, described retarder is at least in sodium phosphate, sodium pyrophosphate, sodium tripolyphosphate, sodium gluconate
Kind.
The Binder Materials of the present invention, with flyash as raw material, reduces environmental pollution, and to the quality requirements of flyash not
Height, takes full advantage of scrap feed material, energy-conserving and environment-protective.
The preparation method of the above-mentioned Binder Materials with flyash as raw material, comprises the following steps:
The first step: weigh each raw material, by flyash, lime, exciting agent mixing, grinding tails over to 80 μm square hole screens and is less than
5%, obtain batch；
Second step: described batch is mixed with water, stirs, obtain raw slurry；
3rd step: described raw slurry is heat-treated 8～16h at 90～98 DEG C of Water Unders, obtains Hydrothermal Synthesis slip；
4th step: described Hydrothermal Synthesis slip filter press is dehydrated, obtains Hydrothermal Synthesis material block；
5th step: after described Hydrothermal Synthesis material block is calcined 30～120min under the conditions of 750～950 DEG C, blow air cold
But grog is obtained；
6th step: take grog 92～95 parts mix with gypsum 5～8 parts, retarder 0.2～1.5 parts, grinding is to 80 μm square holes
Tail over less than 4%, obtain Binder Materials.
The hydro-thermal of the 3rd step processes and carries out in hydro-thermal reaction tank.
The present invention is to obtain after material block prepared to flyash, lime, exciting agent and water or pellet hydrothermal treatment and calcining
To grog, then grog, gypsum and retarder are mixed and made into Binder Materials.Its principle be by hydro-thermal process make lime with
In flyash, active silica and active oxidation reactive aluminum form hydrated calcium silicate and drated calcium aluminate, calcine at a lower temperature
Rear formation dicalcium silicate and seven aluminium ten dicalcium.Wherein seven aluminium ten dicalcium have the highest hydration activity, and dicalcium silicate is due to relatively low
At a temperature of formed, there is a large amount of fault of construction, the most also there is the highest hydration activity, easily reacting formation with water has height
The hydrated product of gelling.
In the present invention, exciting agent can destroy vitreum network structure with the alumina silicate glass precursor reactant in flyash,
Reduce the extent of polymerization of vitreum network structure, be greatly improved reaction rate and the aquation of wherein silica and aluminum oxide and lime
Calcium silicates and the formation rate of drated calcium aluminate, and then improve dicalcium silicate and the content of seven aluminium ten dicalcium in inorganic coagulation material,
Improve the gelling of Binder Materials.
In the present invention, gypsum can react with seven aluminium ten dicalcium and water and form the trithiophenol salt type aquation sulphur aluminic acid that gelling is the highest
Calcium, retarder can regulate seven aluminium ten dicalcium reaction rate so that setting time of Binder Materials of Binder Materials unlikely
In the shortest and affect construction.
The invention has the beneficial effects as follows:
(1) calcination process of Binder Materials grog of the present invention is possible not only to the rigid dicalcium silicate of synthetic water and seven aluminium 12
Calcium, and can be therefore raw material with the low-quality flyash that phosphorus content is high, such as wet method with the residual carbon in burn off flyash
The flyash etc. of discharge, utilization of fly ash rate is big, it is also possible to reduce the flyash pollution to environment；
(2) present invention uses exciting agent to accelerate in hydrothermal treatment process slip the reaction between each component, promotes adding of reaction
Speed and being properly completed, reduces hydro-thermal and processes heat consumption, thus shorten hydrothermal conditions, improve productivity effect and equipment uses effect
Rate；
(3) preparation method of Binder Materials of the present invention is simple, low for equipment requirements, it is not necessary to large-scale equipment, calcining heat
Low, greenhouse gas emissions are few；
(4) characteristic that Binder Materials of the present invention has quick setting and rapid hardening, long-term strength sulfate aggressivity high, resistance to is good, especially
Be applicable to tunnel, under water, saline and alkaline area and coastal area engineering.
