Description
Technical field
The invention discloses a kind of preparation method of bi-component cement based mending mortar, belongs to building material technical field.
Background technology
Concrete repair, protection and to reinforce industry promoted by the degeneration of xoncrete structure, destruction and defect.The U.S.
The concrete for having more than 500,000,000 cubic yards every year is modified.And these concrete are mostly using local different quality former materials
Material is built.In addition, design lack of standardization and ignore for working to tight deadlines construction quality problem all be exist.So repair and just exist
Institute is unavoidable.Annual U.S. owner is for repairing, the cost in terms of protection and reinforcing is about between 120 hundred million to 180 hundred million dollars.
At present, the construction of many Large Infrastructure Projects of China is all completed in succession and is come into operation, in one period from now on
Interior China's building trade will complete by present based on newly-built foundation engineering facility to repairing and renovate these foundation engineerings and set
Strategic change based on applying.So the building trade of coming few decades China will face protection, reinforce and maintenance engineering facility
Immense pressure.At present, extremely urgent is very big one in the industry and civil buildings that builds before China eighties in 20th century
Part is in reinforcing and maintenance timing, and now in some the civilian and engineering workses that builds during construction and use
Concrete quality problem, such as voids and pits, cavity, large area damage etc. is frequently encountered, in terms of road and bridge, this phenomenon is more
Plus substantially, according to incompletely statistics, existing cement concrete pavement will have 20～30% to all suffer from repairing and improve.
At present, traditional method for repairing and mending be using normal concrete or mortar as patching material, but normal concrete or
Mortar all exist one common the characteristics of, i.e. fragility is big and toughness is not enough, is mainly shown as that comprcssive strength is high, tensile strength and glues
Knotting strength is low, and elastic modelling quantity is high and deformability is poor, if using it for concrete repair, easily cause interfacial adhesion loosely, open
The quality problems such as split and cause concrete to damage once again, be restricted in use.Polymer-modified cement mortar is in recent years
The class novel patching material for growing up, it are to mix a small amount of organic polymer in cement mortar, so as to improving cement bonded sand
The composite gelled material of slurry properties, compared with conventional cement mortar, its tensile strength is high, elastic modelling quantity is low, wear-resisting, corrosion resistant
Erosion, impervious, anti-freezing property are excellent, it is adaptable to which the concrete surface layer caused because of carbonization, cavitation erosion, freeze-thaw damage and chemical attack is opened
Split, the repairing of surface deterioration destruction, but in use, air content is difficult to control to, and to ring in production processes of polyalcohol
Border also results in pollution, and polymer is relatively costly, cause cannot large area use, another drawback is the compatibility with road surface
Difference.
Content of the invention
The invention mainly solves the technical problem of：Go out during preparation and use for conventional cement and mending mortar
Existing, with old concrete interface poor compatibility, bonding loosely, using the rear problem for causing concrete to damage once again easy to crack,
Provide a kind of preparation method of bi-component cement based mending mortar, the present invention first by corn straw smashing, then with second pond
Activated sludge, yellow sand etc. are mixed, and collect filter cake after anaerobic fermentation, then by filter cake and cement, Pulvis Talci and calcium chloride solution press than
Example is mixed to prepare component A, then rice husk fermentation is calcined under hot conditionss, by calcining after rice hull ash be dissolved in sodium hydroxide
In solution, after being filtered to remove impurity, concentrated by rotary evaporation is obtained B component, during use, component A is mixed in proportion with B component, is obtained final product
Bi-component cement based mending mortar.Gained mending mortar of the present invention is good with old concrete interface compatibility, is firmly bonded, can be abundant
