Abstract
The present invention is light red mud brick and its making process. The red mud brick is made with red mud 15-50 weight portions, fly ash 35-70 weight portions, lime 8-12 weight portions and silica sand 4-6 weight portions, and through making adobe and steam curing. The making process is simple and environment friendly, and the product has low cost, light weight and high strength.
Description
Technical field
The present invention relates to a kind of wall body building material and preparation method thereof, particularly relate to a kind of light wall brick with industrial waste red mud and fly-ash Preparation.
Background technology
Red mud is the waste that aluminium manufacturer produces the aluminum oxide discharging, and flyash is the waste of fuel-burning power plant discharging, and these wastes of aluminium manufacturer and power plant emission not only need land occupation to stack, and also environment are polluted.Therefore how to utilize these wastes, when reducing pollution, increase the resources of production, just become the problem that people pay close attention to.At present, utilize flyash more, so the processing of flyash is better relatively as the technical scheme of raw material making building brick.And less, and be to use sintering method basically with the technical scheme of red mud making building brick; Though the utilization that these schemes can make red mud obtain, but in the process of firing, inevitably can produce a large amount of sulfurous gas obnoxious flavoures, this the pollution of aluminium manufacturer's waste to environment just occurred having reduced on the one hand, on the other hand the obnoxious flavour that produces in the process of baking bricks situation that environment is polluted once more; In addition, sintering process brickmaking, cost is also big.
Summary of the invention
The objective of the invention is to, a kind of light red mud brick and preparation method thereof is provided.It is main raw material that this method adopts the waste red mud of aluminium manufacturer's discharging and the waste flyash of power station discharging, makes light red mud brick with the method for baking-free.Both utilized waste material, expanded resource, avoided pollution once more again environment.
Technical scheme of the present invention: light red mud brick is characterized in: it is to add water with the following weight proportion raw material to make;
15～50 parts of red muds, 35～70 parts in flyash,
8～12 parts in lime, 4～6 parts of silica sands.
Above-mentioned light red mud brick is to add water with the following weight proportion raw material to make better;
15～30 parts of red muds, 55～70 parts in flyash,
10 parts in lime, 5 parts of silica sands.
In the aforesaid light red mud brick, also include the phosphorus slag of 4～6 parts of pulverizing in the raw material.
The preparation method of aforementioned light red mud brick, characteristics are, by following step preparation;
A, raw material is added the water mixing, is pressed into adobe, the A product;
B, with the A product after with vapor cure finished product.
Among the preparation method of above-mentioned light red mud brick, step b is that the A product are got finished product with steamed after 7～9 hours.
Compared with prior art, the present invention is that the waste flyash that adopts the waste red mud of aluminium manufacturer's discharging and power station to discharge is main raw material, adds lime, silica sand and/or phosphorus slag and does batching, makes light red mud brick with the method for baking-free.Among the present invention, the selection of each raw material, the formation of prescription, employing vapor cure and curing time are determined, all are the results that the applicant obtains by a large amount of experiments.Facts have proved that the present invention fills a prescription rationally, the preparation method is simple, effective.Main raw material among the present invention is red mud and flyash, and the raw material silica sand consumption of resource is less; Both improved the utilization ratio of waste, also reduced simultaneously, and greatly reduced preparation cost, and in preparation process, do not have obnoxious flavour to produce, and can not cause secondary pollution environment to the taking of resource.The present invention has waste utilization rate height, and the preparation method is easy to grasp, and production cost is low, and product weight is light, advantages of high strength; The every technical indicator of product all satisfies standard (national building material industry standard JC239-2001, strength grade MU15, actual measurement ultimate compression strength 14.6Mpa-19.3Mpa, the folding strength 5.3Mpa-5.9Mpa) of national building brick.The present invention has good society, environmental protection and economic benefit.
