Abstract
The invention discloses a modified building residue baking-free brick. The modified building residue baking-free brick is prepared from, by mass, 65 to 75% of building residue, 10 to 15% of sand, 5 to 15% of cement, and 2 to 5% of industrial lime. The modified building residue baking-free brick is prepared via following steps: 1) building residue generated in subway construction processes is subjected to simple ball milling so as to obtain building residue powder; 2) the ingredients above are weighed according to the ratio above, and water-solid ratio is controlled to be 0.20 to 0.24; 3) cement, lime, gypsum, and sand are uniformly mixed with the building residue powder, water is added for uniform mixing, an obtained mixed material is subjected to extrusion forming, and curing under natural conditions for 3 to 7 days, is delivered into a drying oven, and is dried to be constant in weight at 40 to 60 DEG C so as to obtain the modified building residue baking-free brick. The modified building residue baking-free brick is cheap; a large amount of building residue can be recycled; environmental pollution and soil waste are reduced; compressive strength is high; water resistance is excellent; the modified building residue baking-free brick is capable of satisfying performance requirements of building bricks, and can be used for replacing sintering clay bricks.
Description
Technical field
The invention belongs to building material field, particularly a kind of modification dregs is non-burning brick.
Background technology
Along with the continuous propelling of urbanization process, urban track traffic is the vehicles such as subway, light rail especially, because its facility, safety, traffic capacity are subject to greatly the favor of people.But, along with the construction process of subway, light rail, a large amount of dregs can be produced; According to measuring and calculating, the general subway building total length 30 kilometers, approximately produce dregs more than 450 incomparably, these dregs can fill up about 4 national the Water Cubes.A large amount of dregs can cause a lot of problem in stand-by period: such as, the storage location problem of dregs, and a large amount of dregs needs a lot of spaces, and point selection of dissolving in the past, in suburb, is not only destroyed arable land, also impacted local environment.Also have in addition, air pollution problems inherent, the dust in dregs enters air with the wind, affects urban air-quality.If these dregs adopt, heap is abandoned, landfill or the mode as road foundation filler are discongested, then or contaminate environment, occupy a large amount of soil, or utilization ratio and added value low.
Summary of the invention
In order to improve dregs comprehensive utilization ratio and added value further, it is non-burning brick that the present inventor with dregs is that main raw material is prepared into, and what this brick can be used for that alternate country expressly bans fires clay brick.
The object of this invention is to provide the technology of preparing that a kind of modification dregs is non-burning brick.
The technology of the present invention is realized by following scheme:
The mass percent of each component is: dregs: 65%-75%; Sand: 10%-15%; Cement: 5%-15%; Commercial lime: 2%-5%, water-solid ratio: 0.20-0.24.
In addition, according to different purposes needs, the desulfurated plaster that also can add total amount 0 ~ 5% in such scheme is prepared into non-burning brick.
Described dregs refers to metro shield dregs out, and its essential mineral is quartz, alumina and aluminosilicate mineral, and through ball mill ball milling 30 minutes, specific surface area was 18000m
2/ kg-19000m
2/ kg;
Described cement refers to the general purpose portland cement of 42.5 or 52.5 strength grades;
Described gypsum can be desulfurated plaster; Described lime can be commercial lime.
Modification dregs of the present invention is non-burning brick to be prepared in accordance with the following methods, comprises step:
1) get the dregs produced in subway construction process, make into dregs powder through simple ball milling;
2) each component is got in described ratio, water-solid ratio: 0.20-0.24;
3) cement, lime, gypsum, sand are mixed in dregs, then add water and be mixed evenly; Then, by the material extrusion molding mixed, under field conditions (factors) after maintenance 3-7 days, be placed on and dry to constant weight in 40-60 DEG C of baking oven, to obtain final product.
Advantage and disadvantage of the present invention:
1, the technology of the present invention can utilize more, the solid waste of contaminate environment of dissolving, turn waste into wealth; These solid waste not only contaminate environment, generally also can take large-area soil.
2. can produce certain economic benefit, the interest of promoting enterprise and power when solving problem of environmental pollution, further promoting process and the recycling of solid waste.
3. modification dregs of the present invention is non-burning brick has the good feature of environmental protection.Modification dregs of the present invention non-burning brick preparation process energy consumption is low, and can not produce secondary pollution.
4. high, the water-tolerant of the non-burning brick ultimate compression strength of the present invention, can meet building brick performance requirement, can alternate country policy expressly banned fire clay brick.After the non-burning brick oven dry of modification dregs of the present invention, ultimate compression strength can reach 6MPa-15MPa, and coefficient of softening reaches 0.60-0.90.
5. it is convenient that cost is low, starting material obtain.
Mechanism of the present invention:
The main chemical compositions of dregs is silicon-dioxide, aluminum oxide and calcium oxide, belongs to sial resource.Mineralogical composition is quartz, alumina, aluminosilicate mineral mainly.
The dregs that the present invention utilizes metro shield to produce, be finely ground to after powder with the gelling material such as cement, lime, gypsum and water mixture manufacturing hydrated product etc. by a certain percentage, change pore texture and the cementing material of dregs, cementing from originally physical force each other being leaned on to be converted into mineral hydraulic.
