Abstract
The invention discloses a ferronickel slag magnesium phosphate binding material and application thereof. The binding material is prepared from 6-12 parts of ferronickel slag, 12-25 parts of dead burned magnesia, 3-12 parts of phosphate and 1-10 parts of retarder. The ferronickel slag magnesium phosphate binding material is used in structural members requiring high strength in early age period and rush-repair work. The ferronickel slag magnesium phosphate binding material has the advantages of achieving rapid hardening and early strengthening, and being high in strength and small in shrinkage deformation, the interior structure is more compact, the porosity is low, and the durability including water tolerance is improved. Moreover, according to the ferronickel slag magnesium phosphate binding material, innocent treatment of the ferronickel slag is achieved, high-efficiency resource utilization of industrial waste residues is promoted, and on the premise that the mechanical properties of the binding material is guaranteed, the consumption of dead burned magnesia is reduced, the consumption of a non-renewable resource, namely magnesite, and energy loss are reduced, the production cost of the magnesium phosphate binding material is decreased, and therefore, economic benefits and environmental benefits are remarkable.
Description
Technical field
The invention belongs to building material technical field, is related to a kind of Binder Materials, specially using trade waste ferronickel
The ferronickel slag magnesium phosphate cement that slag is prepared, and the application of the Binder Materials.
Background technology
Magnesium phosphate cement has that fast hard, early strong, adhesion strength is high, the dry-shrinkage deformed premium properties such as little, used as one kind
Novel gelled material is received more and more attention, it is adaptable to have component, salvaging of high request etc. to early strength.Phosphoric acid
One of the component that magnesium Binder Materials is used dead burned magnesia is obtained by 1700 DEG C or so high-temperature calcinations of magnesite Jing, due to forging
Burn temperature high, so, from production of construction materials technique, dead burned magnesia is carbon isotopes.
Ferronickel slag is to produce the Water Quenching Slag that ferronickel is discharged using pyrometallurgical smelting process, and liquidus temperature is up to during smelting ferronickel
More than 1700 DEG C.In China, ferronickel slag is the fourth-largest trade waste after scum, slag, red mud, annual generation at present
About 30,000,000 tons of ferronickel slag.But, the utilization rate of ferronickel slag is extremely low, and the overwhelming majority is simply stored up in outdoor mode, is not only taken up
Valuable land resource, and underground water pollution and dust pollution can be brought.The innocuity treatment problem of ferronickel slag is urgently to solve
One of environmental issue certainly.
The content of the invention
The technical problem of solution:In order to overcome the defect of prior art, trade waste ferronickel slag of dissolving realizes ferronickel slag
Resource application, reduce the consumption of dead burned magnesia in magnesium phosphate cement, and still ensure that the gelling material for preparing

Area is 300m2/ more than kg.
Arbitrary described ferronickel slag magnesium phosphate cement is in structural member, the salvaging that early age has high intensity to require
Application.
The present invention principle be:Active component in ferronickel ground-slag participates in hydration reaction, cementing properties water in increase system
Change product formation, it is ensured that the Binder Materials physical mechanics property;Additionally, ferronickel ground-slag also has filing effect, ensureing gelling
Internal structure compactness is improved while Material Physics mechanical property, porosity is reduced.
Beneficial effect:(1) ferronickel slag magnesium phosphate cement of the present invention has fast hard, early strong, high-strength, dry-shrinkage deformed
Little advantage;(2) ferronickel slag magnesium phosphate cement internal structure of the present invention is fine and close, and porosity is low, including resistance to water exists
