Abstract
A Mg-slag brick with high strength is prepared proportionally from reduced Mg slags, broken stone, gypsum, lime and water through mixing, adding water, stirring, natural stacking, die pressing, steam curing and natural drying.
Description
Technical field
The present invention relates to a kind of Mg-slag brick and preparation method thereof, belong to building material field.
Background technology
Can produce a large amount of magnesium reduction slags in industry refining magnesium process, what these slags can not be careless topples over, and it destroys the ecotope and the eubiosis, and processing cost is quite big.At present, be in the method for main raw material brickmaking with industrial residue now, be to be main raw material with flyash basically.Though the method for also useful magnesium slag brickmaking, because the defective of making method self, the brickmaking effect is unsatisfactory.
Summary of the invention
The objective of the invention is to: a kind of Mg-slag brick and preparation method thereof is provided.It is main raw material that this method adopts the magnesium reduction slag that produces in the refining magnesium process, makes high-intensity building brick, and its making method will be easy to grasp, and prescription rationally reduces the pollution of industrial waste to environment, helps the utilization again of waste material.
Technical scheme of the present invention: a kind of Mg-slag brick, it is to make with the water of following weight proportion raw material and raw material total amount 10%～40%;
60～80 parts of magnesium reduction slags, 15～25 parts of rubbles,
1～15 part in gypsum, 3～15 parts in lime.
Above-mentioned Mg-slag brick, it is to make with the water of following weight proportion raw material and raw material total amount 10%～40%;
70～80 parts of magnesium reduction slags, 17～23 parts of rubbles,
5～13 parts in gypsum, 5～13 parts in lime.
In the aforesaid Mg-slag brick, rubble is natural rock or the industrial residue that particle diameter is no more than 10mm.
In the aforesaid Mg-slag brick, rubble is Wingdale, blast-furnace slag or the phosphorus slag that particle diameter is no more than 7mm better.
In the aforesaid Mg-slag brick, gypsum is the plaster of paris, phosphogypsum or industry byproduct desulfurated plaster preferably.
In the aforesaid Mg-slag brick, lime is the unslaked lime or the carbide slag that can generate calcium hydroxide.
The preparation method of aforesaid Mg-slag brick makes by following step;
A, water is added in the magnesium reduction slag, mixing is stacked more than 12 hours, again with rubble, gypsum and lime mixing naturally; Or water added in the mixed raw material, mixing is stacked more than 12 hours naturally; Get the A product;
B, the A product are pressed into adobe, after the seasoning finished product.
Among the above-mentioned Mg-slag brick preparation method, its step b is, the A product are pressed into adobe, vapor cure 1-12 hour, after the seasoning finished product.
Compared with prior art, the invention provides a kind of Mg-slag brick and preparation method thereof.The present invention is a main raw material with a large amount of magnesium reduction slags that produce in the refining magnesium process, adds suitably batching, and adopts suitable preparation method, makes building brick, has both alleviated the pollution of industrial residue to environment, has increased novel material for construction work again.The present invention fills a prescription rationally, making method rationally and be easy to grasp, the brick intensity of making very high (can reach more than the 25MPa) reaches the standard of national building brick.Have be easy to produce, with short production cycle, production cost is low, the characteristics of good product effect.
Embodiment
Embodiment 1.Make Mg-slag brick by following step.
A, get the water of 200Kg, add the magnesium reduction slag of 700Kg, mixing, stacking is 2 days naturally, again with the rubble of 200Kg, the gypsum of 100Kg and the lime mixing of 100Kg; Or earlier the magnesium reduction slag of 700Kg, the rubble of 200Kg, the gypsum of 100Kg and the lime of 100Kg are mixed, adding the water of 200Kg again, mixing was stacked 2 days naturally; Get the A product;
The magnesium reduction slag that magnesium reduction slag can obtain with the magnesium reduction slag that produces in the production of magnesium by pidgeonprocess process or other method.Rubble is Wingdale, blast-furnace slag or the phosphorus slag that is no more than 7mm with particle diameter as aggregate better, also available other natural rock or industrial residue.Gypsum can be used phosphogypsum, the plaster of paris or industry byproduct desulfurated plaster.The lime available energy generates the unslaked lime or the carbide slag of calcium hydroxide.
B, the A product are pressed into adobe, after the seasoning finished product.
Embodiment 2.Make Mg-slag brick by following step.
A, get the water of 250Kg, add the magnesium reduction slag of 750Kg, mixing, stacking is 3 days naturally, again with the rubble of 120Kg, phosphogypsum and the 130Kg lime mixing of 120Kg; Or earlier the magnesium reduction slag of 750Kg, the rubble of 120Kg, the phosphogypsum of 120Kg and the lime of 130Kg are mixed, adding the water of 250Kg again, mixing was stacked 3 days naturally; Get the A product;
B, the A product are pressed into adobe, vapor cure 4～6 hours, after the seasoning finished product.
Can suitably improve the intensity of brick and shorten the production time with vapor cure.
