Description
Technical field
The present invention relates to a kind of recycling of building waste, specifically a kind of gelling material that building waste processes and preparation method thereof of utilizing belongs to the material of construction preparing technical field.
Background technology
Building waste is the solid waste that produces in the construction, maintenance, demolishing process at buildings; Comprise waste material, various wrapping material and other wastes etc. that the mortar that is scattered in waste concrete piece, useless fragment of brick, bituminous concrete piece, the construction process and concrete, brickbat slag, metal, bamboo timber, decorations produce, its staple is main with concrete and sintering common brick.
In Europe, developed country such as U.S.A, day, the recycling of building waste has become the hot issue of present research.To the building waste of different sources and composition, processing mode is different, like the CYCLEAN company of the U.S. building waste to road excavation, adopts microwave technology, reclaims the old asphalt pavement material, and its quality is with newly to mix asphalt road surface material identical, and cost can reduce by 1/3.And the building waste that building demolition is obtained, Singapore is then building waste recycling be processed into iron, timber, leatheroid etc.To pretreated building waste, handle according to its composition, to material of construction such as concrete, sand, stones,, produce recycled cement and regeneration aggregate through certain means preparation material of construction of regenerating.And to flammable building waste, the destructive distillation combustion refuse treatment process of Siemens exploitation can make the various recyclable materials in the rubbish very separate neatly, is recycled, and the combustion gas that produces in the treating processes then is used for generating.Generally speaking, the recycling of building waste has all been obtained substantial progress from theoretical and actual two aspects abroad.
In China, the recycling of building waste has also caused numerous investigators' attention and has carried out big quantity research.In general, its basic ideas are carries out sorting with building waste, thereby carries out classified use, different according to investigator's research object, has obtained a large amount of theoretical property conclusions.As with blue bricks or common brick particle as light-weight aggregate, be aided with less fine aggregate of density or powder again, can make cement products such as better road brick of light in structure aggregate concrete member, ventilation property with load-bearing, heat insulation function and ornamental slab for paving the floor.As with sorting after the waste and old concrete fragmentation, modification is as regeneration aggregate; Waste and old mortar is pulverized the back be used as dry-mixed mortar etc.In the application facet of reality, real mass-producing utilizes the report of building waste, and is at present domestic less.
Analyzing China's building waste treatment technology can find; Although China's building waste is handled thinking and external basically identical; But on concrete technology and implement scale, still be in the junior stage, also do not having sophisticated mass-producing and the complete technological line that utilizes for the urban architecture rubbish of a large amount of complicated components.
At present, the quantity of China's building waste has accounted for 40%～50% of municipal wastes total amount.And most building wastes are handled with the mode of air storage or landfill, consume a large amount of soils, bury great potential safety hazard also for people's living environment.Therefore, building waste being recycled, turned waste into wealth, is to solve the building waste optimal path, also is simultaneously the effective way that economizes on resources, protects existing fragile ecological environment.Because the chemical constitution and the mineralogical character of building castoff are developed its recycle utilization at building field, can finally solve the handling problem of building waste.Amount of literature data shows, utilizes building waste to produce the adulterant of non-burning brick, roadbase, the steady layer of water, regeneration aggregate, dry-mixed mortar, manufacture of cement, is the focus of studying at present.
Say from the meaning of Eco-economy System; Waste is " resource that has misplaced the position "; It is recycled to produce building material, is decontamination, makes one of main method of its resource utilization; Not only can alleviate the pressure of China's urban environment load, also can realize Sustainable development economic and society.
Comprehensive existing document can be found out: aspect building waste production gelling material, mainly be in the form adding grog with adulterant, compare with the cement of producing equal label, reduce the grog parameter; Simultaneously, because its grindability is practiced thrift power consumption.Therefore, can reduce the manufacture of cement cost, reach the purpose of energy-saving and emission-reduction.It is gelling material with cement mainly that building waste is produced non-burning brick, is aided with other industrial slag, under natural or steam-cured condition, produces non-burning brick.When producing road basement material with building waste, building waste mainly is that its gelling material then adopts cement, lime, flyash etc. as aggregate.With the building waste is main raw, and through high-temperature activation, mechanical activation and chemical activation, preparation has the gelling material of the hydraulicity, does not appear in the newspapers yet and leads.
