Abstract
The invention discloses a kind of method that use red mud prepares unburned lightweight aggregate, it is related to technical field of resource utilization of solid waste.Its step is：Red mud, cement, fine sand are pressed 5：2：3 ratio, which adds water, to stir, water-solid ratio 0.22：1,5 10mm ball is then made of ball press, maintenance indoors can dispatch from the factory for three days.The present invention is simple and easy to apply, improves the resource utilization degree of industrial waste, cost is low, energy-conserving and environment-protective, it is easy to promote the use of.
Description
Technical field
The present invention relates to technical field of resource utilization of solid waste, and in particular to one kind is prepared unburned using red mud
The method of lightweight aggregate.
Background technology
Red mud is the industrial waste of alumina producer discharge, and a large amount of store up of these solid waste occupies a large amount of soils, dirty
Underground water source and atmospheric environment have been contaminated, and serious threat is caused to periphery people's property and life security.According to analysis, red mud (burns
Connection) CaO content be up to more than 40%, can be with and containing substantial amounts of cement active ingredient --- the hydraulic material such as calcium silicates
Substituting lime, cement is used for construction material.The extensive comprehensive utilization of resources of red mud meets the industrial policy of country, can not only
A large amount of valuable land resources are saved, preserves the ecological environment, while also generating huge economic benefit, realizes economy and environment
Doulbe-sides' victory development.Based on this, the method that a kind of use red mud of design prepares unburned lightweight aggregate is particularly necessary.
The content of the invention
In view of the shortcomings of the prior art, the present invention seeks to be to provide one kind to prepare unburned light bone using red mud
The method of material, it is simple and easy to apply, the resource utilization degree of industrial waste is improved, cost is low, energy-conserving and environment-protective, it is easy to which popularization makes
With.
To achieve these goals, the present invention is to realize by the following technical solutions：One kind is prepared using red mud to be exempted from
The method of lightweight aggregate is burnt, its step is：Red mud, cement, fine sand are pressed 5：2：3 ratio, which adds water, to stir, water-solid ratio 0.22：
1,5-10mm ball is then made of ball press, maintenance indoors can dispatch from the factory for three days.
Preferably, described red mud is the industrial waste produced by production aluminum oxide, cement uses the common silicic acid of C425
Salt cement；Fine sand is the less river sand of shale content.
Beneficial effects of the present invention：Preparation method is simple and easy to apply, improves the resource of the industrial waste of alumina producer discharge
Change producing level, scientific disposal makes its minimizing, innoxious, recycling and stabilisation, and cost is low, and energy-conserving and environment-protective.
Embodiment
To be easy to understand the technical means, the inventive features, the objects and the advantages of the present invention, with reference to
Embodiment, is expanded on further the present invention.
Present embodiment uses following technical scheme：A kind of method that use red mud prepares unburned lightweight aggregate, it is walked
Suddenly it is：Red mud, cement, fine sand are pressed 5：2：3 ratio, which adds water, to stir, water-solid ratio 0.22：1, then it is made of ball press
5-10mm ball, indoors maintenance can dispatch from the factory for three days.
Red mud described in present embodiment produces the industrial waste produced using alumina producer, and sodium oxide content is high,
It is alkaline big；Cement uses C425 Portland cements；Fine sand is the less river sand of shale content.
Present embodiment is simple and easy to apply, improves the resource utilization degree of the industrial waste of alumina producer discharge,
Efficiently solve red mud largely to store up land occupation, pollute the problem of underground water source and atmospheric environment, protect periphery people's wealth
Production and life security, meet the industrial policy direction of country, save a large amount of valuable land resources, preserve the ecological environment, with huge
Big economic benefit, possesses wide market application foreground.
The general principle and principal character and advantages of the present invention of the present invention has been shown and described above.The technology of the industry
Personnel are it should be appreciated that the present invention is not limited to the above embodiments, and the simply explanation described in above-described embodiment and specification is originally
The principle of invention, without departing from the spirit and scope of the present invention, various changes and modifications of the present invention are possible, these changes
Change and improvement all fall within the protetion scope of the claimed invention.The claimed scope of the invention by appended claims and its
Equivalent thereof.
