Abstract
The invention relates to a roadbed stability material of desulfurized fly ash, lime and fly ash, and its preparation method. The material comprises by weight: 24-30 parts of calcium hydroxide, 60-70 parts of fly ash, 5-15 parts of desulfurized fly ash and 20-26 parts of water. The preparation method consists of: mixing calcium hydroxide, fly ash, desulfurized fly ash and water, thus obtaining the material. In the roadbed stability material of the invention, desulfurized fly ash is employed to partially substitute lime or fly ash, and the performances of lime and fly ash are guaranteed uninfluenced after the mixing of desulfurized fly ash. And even the strength of the material provided in the invention is enhanced to some extent. With simple operation, the method provided in the invention effectively controls the cost of raw materials and has substantial economic benefits, thus boasting broad application prospects.
Description
Technical field
The invention belongs to highway engineering stable material and preparation field thereof, particularly relate to a kind of desulphurize fly ash, lime, flyash subgrade stability material and preparation method thereof.
Background technology
Along with developing rapidly of modern industry; Industrial waste also day by day increases; Though the flyash in ground granulated blast furnace slag and the power station flue has day by day obtained rationally and widely utilizing; But the desulphurize fly ash that is all industrial waste but still is difficult to the chance that is reused; This has not only wasted the part resource, and the accumulation of industrial waste has simultaneously also brought certain pressure to environment.
How from environment and economic angle, the development and use desulphurize fly ash is the important topic of pendulum in face of ours.Can desulphurize fly ash be fully utilized preferably, plays a part very importantly to the utilization of flue gas desulfurization with promoting, and the long-term stability operation and the environment protection of coal-burning power plant also had decisive influence.
Traditional highway engineering stabilized with inorganic binder material mainly contains cement stabilized soil, lime stabilized soil, and lime-fly-ash stabilization soil (being two-ash soil) etc.The desulfurization ash composition is similar in appearance to flyash, and its active instability is lower than flyash simultaneously.
Summary of the invention
Technical problem to be solved by this invention provides a kind of desulphurize fly ash, lime, flyash subgrade stability material and preparation method thereof; Come replacing lime or flyash with the desulphurize fly ash of volume in this subgrade stability material; And it is unaffected to guarantee to mix after the desulphurize fly ash performance of two ashes, even aspect intensity, a certain amount of raising can be arranged; This preparation method is simple to operate, has controlled raw-material cost effectively, and remarkable economic efficiency is arranged, and has a extensive future.
A kind of desulphurize fly ash of the present invention, lime, flyash subgrade stability material, its component comprises:
Slaked lime (main component Ca (OH)
2) 24～30 weight parts, flyash 60～70 weight parts, desulphurize fly ash 5～15 weight parts, water 20～26 weight parts.
Above-mentioned slaked lime is an III level slaked lime, and flyash is III level flyash.
Above-mentioned a kind of desulphurize fly ash, lime, flyash subgrade stability material, its component is: slaked lime 27 weight parts, III level flyash 61 weight parts, desulphurize fly ash 12 weight parts, water 26 weight parts.
Above-mentioned a kind of desulphurize fly ash, lime, flyash subgrade stability material, its component is: III level slaked lime 25 weight parts, flyash 65 weight parts, desulphurize fly ash 10 weight parts, water 24 weight parts mix and form.
Above-mentioned a kind of desulphurize fly ash, lime, flyash subgrade stability material, its component is: III level slaked lime 24 weight parts, III level flyash 61 weight parts, desulphurize fly ash 15 weight parts, water 23 weight parts mix and form.
A kind of desulphurize fly ash of the present invention, lime, flyash subgrade stability preparation methods; Comprise: with slaked lime 24～30 weight parts; Flyash 60～70 weight parts; Desulphurize fly ash 5～15 weight parts; Water 20～26 weight parts mix and form; Its medium-slaking lime is an III level slaked lime, and flyash is III level flyash.
In view of the desulfurization ash composition similar in appearance to flyash, the active unstable characteristics that are lower than flyash simultaneously, the present invention mainly is that to be applied to two grey stable materials with desulphurize fly ash be main contents.
In the present invention, dry combustion method connection desulphurize fly ash with certain volume replacing lime or flyash, guaranteeing even improving on the basis of its quality, also will be improved certain economic benefits, the while is also with the theory of our national refuse reclamation of practical action active response.
Beneficial effect
(1) come part replacing lime or flyash with desulphurize fly ash among the present invention, and it is unaffected to guarantee to mix after the desulphurize fly ash performance of two ashes, even aspect intensity, a certain amount of raising can be arranged;
(2) preparation method of the present invention is simple to operate, has controlled raw-material cost effectively, and remarkable economic efficiency is arranged, and has a extensive future.
