Abstract

The invention discloses a magnesium slag aerated concrete block and a preparation method thereof, which takes the raw materials at the weight ratio of: magnesium-reduced slag of 50-87 portions, cement of 5-30 portions, gypsum of 3-10 portions, coal cinder of 5-25 portions and gas former of 0.05-0.15 portions, and then the product is obtained by adding water of 20-60 percent at the weight proportion of all the dry materials. The product is obtained according to the methods as follows: magnesium-reduced slag, coal cinder, cement, gypsum, water and gas former are mixed evenly at certain proportion and then are treated with standing and maintaining, inverting and incising, autoclaving and conserving. The invention adopts the magnesium slag generated from the magnesium-smelting process as the main raw material to produce 4MPa building aerated concrete block to be conducive to the reuse of the waste, thereby the enterprise not only is free from the expense of waste treatment, but also has new economic benefit, thus avoiding the occupation of land.

Description

Add the preparation method of the magnesium-slag aerated concrete block of cinder
Technical field
The present invention relates to a kind of preparation method who adds the magnesium-slag aerated concrete block of cinder, belong to building material field.
Background technology
In the vacuum metling process of reduction method magnesium, can produce a large amount of magnesium reduction waste residue and cinder.These waste residues are usually as waste disposal, particularly these magnesium reduction waste residues are powder shapes, waste residue is met wind and is easy to produce airborne dust during stacking, can cause serious pollution to the environment of periphery, transportation of waste residue simultaneously and the expense of setting up the stockyard will increase the cost of business processes waste residue, and the land occupation resource.
Summary of the invention
The objective of the invention is to: a kind of preparation method who adds the magnesium-slag aerated concrete block of cinder is provided.With the magnesium reduction waste residue that produces in the refining magnesium process and the cinder of coal-fired furnace kiln is main raw material, the build concrete building block of making or the magnesium-slag aerated concrete finished product of other shape, help the utilization again of waste material,, also avoided taking land resources for enterprise has created new economic benefit.
Technical scheme of the present invention: add the preparation method of the magnesium-slag aerated concrete block of cinder, it is characterized in that: it is to use the following weight proportion raw material, and the water that adds raw material gross weight 20-60% is again made:
50~87 parts of magnesium reduction slags, 5~30 parts of cement,
3~10 parts in gypsum, 5~20 parts of cinders,
0.05~0.15 part of foaming agent.
Among the preparation method of the magnesium-slag aerated concrete block of above-mentioned interpolation cinder, preferably use the following weight proportion raw material, the water that adds raw material gross weight 30-50% is again made:
50~70 parts of magnesium reduction slags, 15~25 parts of cement,
4~7 parts in gypsum, 10~20 parts of cinders,
0.08~0.12 part of foaming agent.
Among the preparation method of the magnesium-slag aerated concrete block of aforesaid interpolation cinder, described magnesium reduction slag and cinder are the cinders that produces with magnesium reduction waste residue that produces in the reduction method vacuum refining magnesium process and coal-fired furnace kiln, or the magnesium reduction slag and the cinder of other method acquisition.
Among the preparation method of the magnesium-slag aerated concrete block of aforesaid interpolation cinder, described gypsum is the plaster of paris, phosphogypsum or the industrially desulfurized gypsum of sulfur acid calcium.
Among the preparation method of the magnesium-slag aerated concrete block of aforesaid interpolation cinder, described foaming agent is meant aluminium powder, aluminium powder cream, hydrogen peroxide, carbide of calcium or chlorinated lime class foaming agent.
The preparation method of the magnesium-slag aerated concrete block of aforesaid interpolation cinder makes by following step;
A, elder generation add the water mixing in proportion with magnesium reduction slag, cinder, cement, gypsum, add the foaming agent mixing again, get the A product;
B, the A product are injected the mould cast molding, stop precuring, upset cutting, steam press maintenance and get finished product through quiet.
Among the preparation method of the magnesium-slag aerated concrete block of above-mentioned interpolation cinder, described mould can be made into difform model according to actual needs, after the injection moulding, obtains the build concrete building block of difform concrete segment or other shape.
Compared with prior art, the invention provides a kind of preparation method who adds the magnesium-slag aerated concrete block of cinder.The present invention is a main raw material with the cinder that a large amount of magnesium reduction waste residues that produce in the refining magnesium process and coal furnace will produce, add suitably batching, and the suitable preparation method of employing, make air-entrained concrete building block finished product for building, make magnesium slag and cinder form material of construction commonly used, both alleviated the pollution of industrial residue, increased novel material for construction work again environment.The present invention fills a prescription rationally, making method rationally and be easy to grasp, the air-entrained concrete building block intensity height of making (can reach more than the 4MPa) can reach the standard of national build concrete building block.Have be easy to produce, with short production cycle, production cost is low, the characteristics of good product effect.
