Abstract
The invention discloses a magnesium slag aerated concrete block and a preparation method thereof. The block is made from the following materials with the weight portions of 60-90 portions of magnesium-reduced slag, 5-30 portions of cement, 3-10 portions of gypsum, 0.05-0.15 portions of gas former and 40-70 percent of water of the total weight of the driers. The materials should be added in the following order during the preparation: the magnesium-reduced slag, the water, the cement and the gypsum and the gas former, which are evenly mixed. And a product is obtained after the static arrangement for the pre-nourishing, the inverting cleavage and the autoclave curing. The invention uses the reduced slag produced in the Mg-smelting process as the main raw material to make building used concrete blocks with high strength of 5MPa above, which is beneficial to the reutilization of waste materials. Enterprises do not have to pay for the slag treatment, creates new economic benefits and avoids the occupation on land resources.
Description
Technical field
The present invention relates to a kind of magnesium-slag aerated concrete block and preparation method thereof, 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 residues.These waste residues are usually as waste disposal, but these magnesium reduction waste residues are pulverulent, be difficult for condensing, usually need just can condense slowly more than 28 days, therefore before the powdered waste residue does not condense, the waste residue of stacking is met wind and is easy to produce airborne dust, serious environment pollution has very strong contaminative, be can not be careless topple over, they can destroy the ecotope and the eubiosis, therefore stack again after also needing waste residue handled, need special stockyards to stack, also need trucking costs and set up the expense in stockyard and stack these waste residues, increased 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 magnesium-slag aerated concrete block and preparation method thereof is provided.To refine the magnesium reduction waste residue that produces in the magnesium process is main raw material, make the finished product of build concrete building block or other shape, help the utilization again of waste material, enterprise does not only need to pay the expense of handling waste residue, and, also avoided taking to land resources for enterprise has created new economic benefit.
Technical scheme of the present invention: a kind of magnesium-slag aerated concrete block is characterized in that: it is to use the following weight proportion raw material, and the water that adds siccative gross weight 40～70% is again made;
60～90 parts of magnesium reduction slags, 5～30 parts of cement,
3～10 parts in gypsum, 0.05～0.15 part of foaming agent.
Above-mentioned magnesium-slag aerated concrete block, the most handy following weight proportion raw material, the water that adds siccative gross weight 50～60% is again made;
70～80 parts of magnesium reduction slags, 15～25 parts of cement,
4～7 parts in gypsum, 0.09～0.12 part of foaming agent.
In the aforesaid magnesium-slag aerated concrete block, described magnesium reduction slag is the magnesium reduction waste residue that produces with in the reduction method vacuum refining magnesium process, or the magnesium reduction slag of other method acquisition.
In the aforesaid magnesium-slag aerated concrete block, described gypsum is the plaster of paris, phosphogypsum or the industry byproduct desulfurated plaster of sulfur acid calcium.
In the aforesaid magnesium-slag aerated concrete block, described foaming agent is meant aluminium powder or aluminium powder cream.
Aforesaid magnesium-slag aerated concrete block is made by following step;
A, elder generation add the water mixing with magnesium reduction slag, add cement and gypsum mixing again, add the foaming agent mixing at last and make slurry, get the A product;
B, pour the A product in mould cast molding, stop precuring, upset cutting, steam press maintenance and get finished product through quiet.
Compared with prior art, the invention provides a kind of magnesium-slag aerated concrete block and preparation method thereof.The present invention is a main raw material with a large amount of magnesium reduction waste residues that produce in the refining magnesium process, add suitably batching, and the suitable preparation method of employing, make build concrete building block finished product, make the magnesium slag 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 concrete segment intensity height of making (can reach more than the 5MPa) 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.
