Description
Technical field
The present invention relates to baking-free building blocks and manufacture method thereof that a kind of building waste is made, belong to environmental protection technical field.
Background technology
Existing building has various ways with building block, traditional building block is formed through firing by clay, the defective one of this building block is the destruction that is easy to cause land resources, the 2nd, need sintering, waste energy, and be easy to pollute environment, the 3rd, because the external and internal compositions of this building block is identical, often surface ratio is more coarse, influences attractive in appearancely, and surface strength is also restricted.
On the other hand, a large amount of rubbish have been produced in the construction and decoration process and in the process of demolition of buildings based on inorganic mineral, these rubbish can be called building waste, the inorganics based on inorganic oxide and inorganic salt wherein can be called mineral materials, according to existing regulation, these rubbish should focus on special disposal field and handle, and common processing mode has two kinds, and a kind of is to be deposited into the rubbish stockyard; Another kind is the bed course as interim construction road, still will be scavenged into the rubbish stockyard at last.Because the non-degradable of building waste, the accumulation of building waste will take a large amount of places, and can bring problem such as sand, realize the recycle of mineral wealth, be the major issue of pendulum in face of ours.
Summary of the invention
For overcoming the defective of prior art, the invention provides a kind of baking-free building blocks of building waste manufacturing and the manufacture method of this building block thereof, that adopts that the present invention can be a large amount of utilizes building waste as raw material, has realized turning waste into wealth, and helps the recycle of physical resources.
The present invention realizes that the technical scheme of above-mentioned purpose is: the baking-free building blocks that a kind of building waste is made, its raw material mainly comprises mineral materials, low-water cement and the glass fibre that comes from building waste.
A kind of manufacture method of baking-free building blocks comprises the steps:
(1) from building waste, selects mineral materials;
(2) batching: take by weighing required mineral materials, shale, glass fibre, cement and other raw materials in proportion;
(3) grinding: the fineness that oversize material is milled down to requirement;
(4) grinding is good material and leftover materials add water mixing stirring, form slip;
(5) block forming;
(6) natural curing forms product.
Because the mineral materials that will come from building waste not only helps reducing the final quantity discharged of building waste as the main raw material of making building block, has protected environment, but also has saved clay, has avoided the destruction to land resources; This building block utilizes the strong rubber knot ability of low-water cement, and has added the glass fibre that helps improving the integral coherence energy, and the good product quality of producing does not need to carry out sintering, and saved the energy, has avoided smoke pollution; This in addition building block helps reducing the production cost of building block, has improved economic benefit.
Description of drawings
Fig. 1 is the schematic flow sheet of the inventive method.
Embodiment
Referring to Fig. 1, the invention provides the baking-free building blocks that a kind of building waste is made, its raw material comprises mineral materials, low-water cement, flyash, glass fibre and the cement water reducing agent that comes from building waste, and weight ratio is: mineral materials is that 100 parts, low-water cement are 100-120 part, flyash 25-30 part, glass fibre 10-20 part, cement water reducing agent 0.5-1.5.
Described low-water cement can adopt 425# or 525# low-water cement.
Described glass fibre also can adopt other natural plant fibres with certain intensity or regenerated fiber to substitute.
Described unclassified stores can be various other mineral particles or its combinations such as flyash, metallurgical tailings sand; under the situation of above-mentioned material proportion; the addition of described flyash can be 0-30 part; because flyash has certain hydraulicity and binding property; not only play filling effect; and with respect to the mineral materials that comes from building waste, it also has certain effect to intensity.
The described preparation method who comes from the mineral materials of building waste is: its to the urban architecture material sort successively, magnetic separation, primary fragmentation and gravitational segregation, building waste is separated into heavy material, light material and mineral materials.
Described letter sorting can be adopted artificial or mechanical system, other materials such as the reinforcing bar of some large or bulks in the building waste, plank are sorted out from mineral materials, because the kind of material is few in the building waste, and the volume or the length of the other materials outside the mineral materials are bigger, after letter sorting, remaining rubbish material all is mineral materials basically.The other materials that sorts out mainly comprises organic materialss such as metallic substance, wood materials, plastics, and these materials can carry out recycling according to character separately.
Can carry out magnetic separation after the letter sorting, described magnetic separation generally can be adopted outstanding suction formula magnetic separator, recycles so that the iron block that does not sort out in the rubbish sucked out, and avoids the detrimentally affect of iron block to follow-up equipment simultaneously.
Described primary fragmentation can adopt jaw crusher, this crusher in crushing is more even than the raw meal particle size after big, simple in structure, the fragmentation, and simple in structure, the working cost and the maintenance cost of equipment itself are relatively large, are suitable for the material fragmentation of this composition of building waste and character complexity.
Can will be divided into for two steps in the primary fragmentation in case of necessity, the first step adopts above-mentioned jaw crusher fragmentation, and bulk crushing is become fritter, the second step roll crushing crusher machine, be suitable for the bigger material of hardness in broken and in small, broken bits.
Described gravitational segregation can be multistage jigging sorting or other suitable sorting technologies, rubbish material is divided into than the heavy material based on metal of mineral materials weight, than mineral materials light light material and described mineral materials based on organic materials, and described heavy material and light material all can carry out resource utilization according to character separately and recycle.
As required, can carry out the secondary magnetic separation to mineral materials behind the gravitational segregation, isolate iron material wherein.
The secondary breaking of described mineral materials can be adopted roller crusher or ball mill.
Described mineral materials can carry out three magnetic separation through after the secondary breaking, further to isolate the iron material that remains in the mineral materials.
In grinding, the material of all bulks should be sent into the pulverizer grinding, described pulverizer is generally ball mill, unclassified stores together can also be sent into pulverizer and carry out grinding, realizes the thorough mixing of various materials in the process of grinding.When the fineness of various materials all meets the requirements, also can cancel the grinding step.When various materials are all sent into the pulverizer grinding, mix again with regard to not needing behind the grinding, directly add the water stirring pulping and get final product.
Below, provide the embodiment of several material proportions, unlisted hardening accelerator and water reducer in these prescriptions, the user can be according to actual needs and the prior art that relates to hardening accelerator and water reducer freely select for use.
