Description

A kind of ferronickel slag magnesium phosphate cement mortar and its application
Technical field
The invention belongs to building material technical field, it is related to a kind of cement-based material, specially using trade waste nickel The ferronickel slag magnesium phosphate cement mortar that scum and flyash are prepared, and the cement mortar application.
Background technology
Dry-mixed mortar has the quality of production stable and secure, workability is more with superior, product category and can root The features such as according to engine request flexible design, saving non-renewable resources, site operation airborne dust less, progressively obtains in China big city Popularization and application, replace Site mortar.
Magnesium phosphate cement has that fast hard, early strong, adhesion strength is high, the dry-shrinkage deformed premium properties such as small, it is adaptable to early stage Intensity has the component of high request, salvaging etc..But one of the component that magnesium phosphate cement is used dead burned magnesia is highly energy-consuming Product, is obtained by magnesite through 1700 DEG C or so high-temperature calcinations, not only needs to consume non-renewable magnesite resource, and production High cost.
The characteristics of ferronickel slag is content of MgO high, is the fourth-largest trade waste after scum, slag, red mud.China is every About 30,000,000 tons of the ferronickel slag that year produces, but its utilization rate is extremely low, and the overwhelming majority is simply stored up in outdoor mode, does not only take up treasured Expensive land resource, and underground water pollution and dust pollution can be brought.
In summary, production magnesium phosphate cement needs to consume a large amount of non-renewable resources and the energy, and production cost is high；It is high The ferronickel slag of content of MgO needs to obtain harmless treatment；Modern building technology progress and the enhancing of Environment Protection Responsibility, it is desirable to use less Or do not use Site mortar.
The content of the invention
The technical problem of solution：In order to overcome the defect of prior art, this class solid waste of solution ferronickel slag is harmless Change is processed, and reduces magnesium phosphate cement sill production cost, with reference to the advantage of dry-mixed mortar, is set in existing magnesium phosphate cement component On meter, the dead burned magnesia in magnesium phosphate cement is substituted with ferronickel ground-slag part, replace what is commonly used in mortar with ferronickel slag aggregate Siliceous aggregate, it is calcareous gather materials, prepare the fine and close ferronickel slag phosphorus of high-early-strength, high bond strength, dry-shrinkage deformed small, internal structure Sour magnesium cement mortar.
Technical scheme：A kind of ferronickel slag magnesium phosphate cement mortar, by weight, the cement mortar includes ferronickel slag collection 25~50 parts of material, 4~8 parts of ferronickel ground-slag, 6~15 parts of flyash, 10~20 parts of dead burned magnesia, 3~10 parts of phosphate, slow setting 1~7 part of agent.
Preferably, in the cement mortar moisture content of each component below 1%.
Preferably, the modulus of fineness of the ferronickel slag aggregate is 0.7~3.0, and wherein content of MgO is more than 20%.
Preferably, the specific surface area of the ferronickel ground-slag is 200~300m2/ kg, wherein content of MgO are more than 20%.
Preferably, the flyash is II grade and above Class F fly ash.
Preferably, the specific surface area of the dead burned magnesia is 200~300m2/ kg, wherein content of MgO more than 90%.
Preferably, the phosphate is at least one in potassium dihydrogen phosphate, ammonium di-hydrogen phosphate, sodium dihydrogen phosphate；It is described Phosphatic specific surface area is 200~300m2/kg。
Preferably, the retarder is at least one in borax, boric acid, sodium tripolyphosphate；The ratio table of the retarder Area is 300m2/ more than kg.
Ferronickel slag magnesium phosphate cement method for preparing mortar of the present invention is：Desired each component material meter will be met Amount, will be homogenized in ferronickel ground-slag, flyash, dead burned magnesia input mixer first, stir 1~2min；Again by phosphate, slow It is homogenized in solidifying agent input mixer, stirs 1~2min；Fully mixed with previous material during ferronickel slag aggregate finally is put into mixer Close uniform, stir 1~2min, kept dry.
Any described ferronickel slag magnesium phosphate cement mortar is in structural member, the salvaging that there is high intensity requirement early age Application.
Application of any described ferronickel slag magnesium phosphate cement mortar in wall coating, tile bonding.
Principle of the invention is：(1) generally slurry-aggregate Interface transition region be mortar, defect in concrete be enriched with, and The weak area affected the mechanical properties with endurance quality, and with ferronickel slag aggregate replace natural sand stone, ferronickel slag aggregate surface with There is hydration reaction between slurry, interfacial transition zone been significantly enhanced；(2) ferronickel ground-slag is not only involved in hydration reaction, while Dense packing effect effect is also acted as, thus, mortar internal structure is finer and close, and porosity is low.Thus, using nickel of the present invention Scum magnesium phosphate cement causes that the mechanical property comprising tensile strength is significantly improved, and including including water resistance Durability is improved significantly.
Beneficial effect：(1) there is ferronickel slag magnesium phosphate cement mortar of the present invention fast hard, early strong, high-strength, drying shrinkage to become The small advantage of shape；(2) ferronickel slag magnesium phosphate cement mortar of the present invention can improve the mechanical property of slurry-aggregate Interface and resistance to Long property；(3) ferronickel slag magnesium phosphate cement mortar of the present invention is capable of the hole of dense packing effect slurry-aggregate Interface, promotes in it Portion's structure is finer and close；(4) height contains during ferronickel slag magnesium phosphate cement mortar of the present invention fully efficiently make use of ferronickel slag The MgO of amount, so as to reduce the consumption of dead burned magnesia in magnesium phosphate cement sill, reduces energy consumption and non-renewable resources Consumption；(5) present invention replaces non-renewable natural sand stone resource using ferronickel slag aggregate, not only contributes to building material industry Sustainable development and ecological protection, also larger amount of ferronickel slag this bulk solid waste of consuming.
