Abstract
The invention relates to a magnesium slag building block used for a construction material, which has the characteristics of high intensity and high stability. The technical proposal provided by the invention is prepared by the materials according to the weight percentage as follows: 35 to 60 percent of magnesium slag coagulating material, as well as 65 to 40 percent of furnace slag or mineral slag. The magnesium slag coagulating material comprises the materials of the weight percentages as follows: 70 percent of magnesium slag, 18 percent of clinker aggregate as well as 12 percent of gesso. The magnesium slag comprises 9 to 11 percent of MgO and 41 percent of CaO; the gesso comprises 10 to 12 percent of CaSO4 question mark 2H2O; and the clinker aggregate comprises 62 to 70 percent of CaO. The magnesium slag building block used for a construction material can be employed to improve the stability of a magnesium slag ash crystal structure, and effectively solves the difficulties of easy cracking and expanding of a common magnesium slag building block. The preparation method thereof is easy to be grasped and the formula is reasonable.
Description
Technical field
The invention belongs to building material field, be specifically related to a kind of high-strength magnesium slag building block that is used for material of construction.
Background technology
Can produce a large amount of magnesium slags in industry refining magnesium process, the magnesium slag is toppled over the destruction that can cause ecotope, and processing cost is very big, utilizes magnesium slag ash producing building material both can turn waste into wealth, and also can reduce the environmental pollution that waste discharge causes.Have the method with the brickmaking of magnesium slag in the market, but there are a lot of shortcomings in these methods, certain methods is directly to make material of construction with the magnesium slag, does not add other compositions; The other method is added compositions such as gypsum, for example application number is that 200610200648.9 Chinese invention patent discloses Mg-slag brick with high strength and preparation method thereof, by 60-80 parts of magnesium reduction slags, 10-25 parts of rubbles, gypsum is or/and 1-15 parts in lime, magnesium reduction slag is added water with other raw material with steamed after 1-3 hours again to be mixed, compression moulding, make after the drying, these methods are because the proportion of composing of added ingredients and magnesium slag is unreasonable, very easily cause the material of construction of production the big area explosion to occur, swelling has influenced the stability of Mg-slag brick greatly.Therefore, press for a kind of more stable magnesium slag building block for construction of magnesium slag ash crystalline structure of filling a prescription rationally, make.
Summary of the invention
Technical problem to be solved by this invention provides the magnesium slag building block for construction of a kind of high strength, high stability.
For solving the problems of the technologies described above, technical scheme provided by the invention is: a kind of magnesium slag building block for construction, make with the following weight proportion raw material: magnesium slag coagulating material 35%-60%, slag or slag 65%-40%.
As a kind of optimized technical scheme, described magnesium slag building block for construction is made with the following weight proportion raw material: magnesium slag coagulating material 60%, slag or slag 40%.
Described magnesium slag coagulating material is made up of the following weight proportion raw material: magnesium slag: 70%; Grog: 18%; Gypsum: 12%.Contain MgO:9%-11%, CaO:41% in the described magnesium slag; Contain CaSO in the gypsum
42H
2O:10%-12%; Contain CaO:62%-70% in the grog.
It is main raw material that the magnesium slag that produces in refining magnesium process is adopted in this invention, makes high-intensity magnesium slag building block for construction, adopts this invention also can reduce the pollution of industrial waste to environment, helps the utilization again of waste material, and its making method is easy to grasp, and prescription is reasonable.This invention has greatly improved the stability of magnesium slag ash crystalline structure, can effectively solve common building and be prone to explosion, an expansible difficult problem with the building block of magnesium slag.
