Abstract
The invention discloses a kind of adulterant that is used for building materials and preparation method thereof, it is by most building solid castoff, by the physics homogenizing, and a kind of green building material that forms through the special producing processes.Building solid castoff in this adulterant is the chief component of urban architecture rubbish; promptly build or during demolition of buildings; the flood tide solid waste that produces; through recycling, can use in a large number in commerical ready-mixed concrete, commodity mortar, cement and the building materials field such as concrete prefabricated, equivalent replaces existing flyash or breeze or part cement; save cost; protected environment effectively, met national recycling economy, the refuse reclamation policy.
Description
One, technical field
The present invention relates to a kind of adulterant and preparation method, this adulterant is applicable in commerical ready-mixed concrete, commodity mortar, cement and the building materials field such as concrete prefabricated.
Two, background technology
Chinese Urbanization is built the quickening of process, and all will produce a large amount of urban architecture rubbish every year, and building solid castoff then is the chief component of urban architecture rubbish, accounts for 60%～70%.Building or during demolition of buildings, can produce the solid waste of flood tide, comprising waste material that the mortar that is scattered in waste concrete piece, the construction process and concrete, brickbat slag, metal, timber, decorations produce and other waste etc.
Though China has just issued " treatment of Municipal Solid Waste method " as far back as nineteen ninety, for the building waste processing provides foundation.But treating method is single, promptly arrives given place landfill or backfill, so not only takies a large amount of soil space resources, goes back serious environment pollution, causes the wasting of resources, is unfavorable for Sustainable development.In recent years, domestic and international researchist utilized technical at building waste, generally the stone in the waste concrete was reclaimed, and used in the concrete as regeneration aggregate and natural aggregate mixing.But because regeneration aggregate adheres to the mortar of inequality, cause physical index instabilities such as the crush index of such regeneration aggregate and water-intake rate, have a strong impact on the physics and the mechanical property of institute's concrete batching.
Three, summary of the invention
Technical problem to be solved by this invention provides a kind of adulterant; this adulterant can be as flyash or breeze; be spiked in commerical ready-mixed concrete, commodity mortar, cement and the field such as concrete prefabricated; and concrete physics and the mechanical property of being prepared do not had any detrimentally affect; not only made full use of building solid castoff; protect environment, and greatly reduced cost.In addition, the present invention also provides the preparation method of this adulterant.
A kind of adulterant that is used for building materials is characterized in that the component of adulterant and weight percent are: loss on ignition 6.15%, SiO
238.67%, CaO 24.86%, and MgO 5.68%, Fe

In addition, the present invention also provides the preparation method of above-mentioned adulterant: at first collect building waste, again by foreign material such as the metal in artificial or the machinery rejecting building waste, timber, plastics, waste concrete piece, clay brick or tile etc. are mixed by 80%～90% weight ratio waste concrete and 10～20% weight ratio clay bricks or tile, be crushed to the particle that maximum particle diameter is no more than 20mm earlier, mill, the material surface area of milling out is controlled at 400m
2/ kg～450m
2/ kg.
The present invention compared with prior art has following characteristics:
(1) the most starting material in the building solid castoff have been fully utilized, compare with the stone in reclaiming discarded concrete, it is simple to have technology, advantage such as easy to operate, and a large amount of land resourcess have been saved, reduce environmental pollution, protected ecotope, helped the Sustainable development of country;
(2) technical indicator of adulterant near in addition surpass the technical indicator of flyash, so can substitute flyash fully, the alternative breeze of part is applied in the building field, and can any detrimentally affect not arranged to finished product.
In the laboratory, foreign material such as metal, timber, plastics in the artificial rejecting building waste, waste concrete piece, clay brick, tile, useless ceramic tile, wall decoration material are mixed according to the above ratio, be crushed to the particle that maximum particle diameter is no more than 20mm earlier, mill, the material fineness of milling out is controlled at 400cm again
2/ g～450cm
2About/g.Its Material Physics index sees Table 1, by table 1 as seen, its performance near or surpass the breeze technical indicator.
Table 1 S95 breeze and adulterant technical indicator comparison sheet of the present invention
Carry out the concrete performance simultaneous test with the material of milling at last, the results are shown in Table 2.By table 2 result as seen, its equivalent replaces flyash or breeze, does not influence concrete physics and mechanical property substantially.
Table 2 concrete performance contrast table
Annotate: 1, strength grade of concrete is C30;
2, C-Green Dragon mountain, Nanjing P.042.5;
3, the precious S95 breeze of KF-Nanjing plum;
4, FA-Huaneng Group, the Nanjing II of power plant level ash;
5, S-medium coarse sand (natural), FM=2.6;
6, G-5 ~ 31.5mm rubble (natural);
7, Ad-retardation water reducing agent;
8、SP＝42％；
9、W/B＝0.44；
10, concrete appearance solid colour after the form removal.
Above-mentioned testing data is made under the more satisfactory situation in laboratory, from practical situation a certain distance is arranged still, especially homogeneity, the stability of material of milling out is crucial, but this can overcome the deficiency of this respect by the adjustment of production technique and production formula fully.
