Abstract
The invention relates to stabilized macadam containing desulfurization ash, lime and fly ash, and a preparation method thereof. The stabilized macadam comprises the following components in part by weight: 6 to 8 parts of slaked lime, 14 to 19 parts of fly ash, 1 to 4 parts of desulfurization ash, and 73 to 80 parts of macadam, and 6 to 8 parts of water; and the preparation method comprises the following steps of: mixing slaked lime, fly ash, desulfurization ash, macadam, and water. The stabilized macadam with a small grain size can meet the requirement of highway engineering on the performance of an inorganic binding material, and is low in cost; and the preparation method is simple and environment-friendly, reduces cost, ensures that the application of industrial waste desulfurization ash is maximized, and has good economic and social benefits and wide application prospect, and new equipment is not needed.
Description
Technical field
The invention belongs to inorganic bond material of highway engineering and preparation field thereof, particularly relate to a kind of stabilization gravel that contains desulphurize fly ash, lime, flyash and preparation method thereof.
Background technology
Nearly two during the last ten years, and lime, flyash are more and more common as the stability material that makes an addition to various great soil groups and rubble, and in the special subgrade construction in road engineering, because the roadbed filling consumption is big, lime and flyash consumption be increase thereupon also.
Meanwhile; 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.
Summary of the invention
Technical problem to be solved by this invention provides a kind of stabilization gravel that contains desulphurize fly ash, lime, flyash and preparation method thereof, and this fine grain size rubble can satisfy the inorganic bond material performance demands of highway engineering; The preparation method is simple, and no new installation requirement has reduced cost, has a extensive future.
A kind of stabilization gravel that contains desulphurize fly ash, lime, flyash of the present invention, its component comprises:
Slaked lime (main component Ca (OH)
2) 6～8 weight parts, flyash 14～19 weight parts, desulphurize fly ash 1～4 weight part, rubble 73～80 weight parts, water 6～8 weight parts.
Said rubble is mainly 5mm～31.5mm graded broken stone and forms.
Described slaked lime is the III level, and flyash is the III level.
Above-mentioned a kind of stabilization gravel that contains desulphurize fly ash, lime, flyash, its component are III level slaked lime 6 weight parts, III level flyash 18 weight parts, desulphurize fly ash 1 weight part, rubble 75 weight parts, water 7 weight parts.
Above-mentioned a kind of stabilization gravel that contains desulphurize fly ash, lime, flyash, its component are slaked lime 7 weight parts, III level flyash 15 weight parts, desulphurize fly ash 3 weight parts, rubble 75 weight parts, water 7 weight parts.
Above-mentioned a kind of stabilization gravel that contains desulphurize fly ash, lime, flyash, its component are III level slaked lime 6 weight parts, flyash 14 weight parts, desulphurize fly ash 4 weight parts, rubble 76 weight parts, water 6 weight parts.
A kind of preparation method who contains the stabilization gravel of desulphurize fly ash, lime, flyash of the present invention comprises:
With slaked lime (main component Ca (OH)
2) 6～8 weight parts, flyash 14～19 weight parts, desulphurize fly ash 1～4 weight part, rubble 73～80 weight parts, water 6～8 weight parts mix and form.
In this invention; Industrial waste sintering dry desulphurization ash is added in the two-ash broken stones as a kind of novel adulterant; In order to lime in the two-ash broken stones of instead of part or flyash; On the basis that does not influence performances such as the original intensity of two-ash broken stones; Can significantly reduce cost, good economic benefit is arranged.This invention also will be opened a valid approach for the solution of industrial waste desulphurize fly ash, reduce the wasting of resources, obvious social benefit.
Beneficial effect
(1) stable fine grain size rubble of the present invention can satisfy the inorganic bond material performance demands of highway engineering, and cost is low;
(2) preparation method of the present invention is simple, and no new installation requirement reduces cost, and makes the application of industrial waste desulphurize fly ash to maximize, and the protection environment has good economic benefit and social benefit, has a extensive future.
