Description
Technical field
The invention belongs to field of mortar, specifically disclose a kind of geo-polymer mending mortar and its system with rust prevention function
Standby and application method.
Background technique
Geo-polymer refers to the cementitious material formed using the activated silica aluminum former material of low calcium by alkali-activated carbonatite, is swashing
Under the action of sending out agent, Si-O, Al-O key in activated silica aluminum raw material are broken, and form [SiO4]4-、[AlO4]5-Tetrahedron,
The inorganic polymer of O-Si-O-Al-O network-like structure is formed using polycondensation, has fast solidifying, early strength high, resistance to
The advantages that high temperature, acid-alkali-corrosive-resisting.Mending mortar refers to a kind of mortar for concrete structural surface defect mending or reinforcing,
Compression strength, caking property, crack resistance and waterproofness with higher.Geo-polymer mending mortar belongs to inorganic mineral polymerization
Object mending mortar, the performance indicators such as compression strength, adhesive strength, waterproof performance are superior to general cement base mending mortar,
But there are problems that setting time is short, poor fluidity and be not easy to construction operation, while asking at present there is also preparation cost is high
Topic.In addition, mending mortar in actual use, the structure or position for needing to repair be frequently present of reinforcing bar directly it is exposed or
The concrete or the serious inadequate phenomenon of screed thickness of reinforcing bar are wrapped up, this requires mending mortars there should be certain resistance rust function
Energy.
However, there is no attention this point in existing technology, and such as: the patent application of Publication No. CN107935520A
Technology discloses a kind of high-performance polymer mending mortar, which does not crack after having hardening, do not shrink, by force
The advantages that degree is high, freeze-thaw resistance is good, anti-fluorine ion permeability is strong, but its anticorrosion performance, composition material are not referred in technology
In be free of corrosion inhibitor；The patent application technology of Publication No. CN104844078A discloses a kind of polymer mending mortar and its system
Preparation Method, the polymer mending mortar comprehensive performance is also very excellent, but corrosion inhibitor is also free of in its composition material.
It is being that can generate a certain amount of high alkaline waste liquor containing aluminium in the production process to process raw material with aluminium alloy, it should
The main component of waste liquid is sodium metaaluminate and sodium hydroxide.The waste liquid generally require first be neutralized it is up to standard after could arrange
It puts, not only consumes acid neutralizating medicine agent, while the aluminium contained in waste liquid does not recycle the waste for be easy to causeing resource, so useless to this
The high-efficiency resource recycling of liquid is also a urgent problem to be solved.
Summary of the invention
It is former to alleviate the problem of current geo-polymer mending mortar preparation cost is high, without rust prevention function and aluminium alloy
The high efficient Utilizing question of alkaline mixed waste liquor containing aluminium generated in material process, the present invention provides one kind to have resistance rust function
