Abstract
The invention provides a lightweight aggregate block made from waste clay bricks and a preparation method thereof. The lightweight aggregate block comprises the following components in part by weight: 40 to 45 parts of waste clay bricks, 30 to 35 parts of liquid slag, 7 to 12 parts of fly ash, 13 to 18 parts of cement and 5 to 7 parts of water. The preparation method mainly comprises the following process steps of: raw material mixing, compression molding, curing, watering and airing. The preparation method has the advantages of effectively reducing volume weight on the premise of reaching a pressure strength standard, effectively utilizing waste and reducing production cost.
Description
Technical field
The invention belongs to building materials field, particularly relate to a kind of method of utilizing building waste to produce the light-weight aggregate building block, be specifically related to a kind of light-weight aggregate building block of processing with refuse clay brick and preparation method thereof.
Background technology
Existing building block is to be raw material commonly used with slag, coal gangue mostly, but along with the increasing substantially of demand, these supplies of raw material are more and more nervous, and the production cost of manufacturer also raises gradually.Simultaneously slag, coal gangue are insufficient because of burning sometimes, and carbon content is high, have according to the statistics made by the departments concerned up to 36.03%, generally all exist with the form of coke, therefore, water-intake rate is bigger, resistivity against fire is poor.In addition, along with the quickening of urban construction and urban renewal, the building back of removing produces a large amount of building waste and refuse clay brick, not only takes up an area of in a large number, contaminate environment, but also will spend considerable processing costs.
Summary of the invention
The object of the invention is to overcome the deficiency of prior art, and a kind of method of utilizing building waste to produce the light-weight aggregate building block is provided, and is specifically related to a kind of light-weight aggregate building block of processing with refuse clay brick and preparation method thereof.
Technical scheme of the present invention is:
The invention provides a kind of light-weight aggregate building block of processing with refuse clay brick, the parts by weight of its feed composition and each component are: refuse clay brick: 40～45 parts; Liquid slag: 30～35 parts; Flyash: 7～12 parts; Cement: 13～18 parts; Water: 5～7 parts.
Preferably, in the above-mentioned light-weight aggregate building block raw material, said refuse clay brick is that unit weight is 900Kg/m
3～1000Kg/m
3, particle diameter is the refuse clay brick of 4～8mm.。
Preferably, in the above-mentioned light-weight aggregate building block raw material, said liquid slag is that particle diameter is the liquid slag of 2～4mm.
Preferably, in the above-mentioned light-weight aggregate building block raw material, said flyash should meet the II level flyash in " flyash that is used for cement and concrete ".
Preferably, in the above-mentioned light-weight aggregate building block raw material, said cement is the cement of strength grade 32.5
A kind of preparation method of light-weight aggregate building block of processing with refuse clay brick, the light-weight aggregate building block prepares by following step:
(1) takes by weighing each component according to light-weight aggregate building block composition of raw materials, mix, obtain mixture;
(2) adopt the vibration pressurization, mixture is prepared moulding;
(3) natural curing or vapor cure are carried out in the building block of compression moulding;
(4) after the building block that maintenance finishes, in building block, water;
(5) static the drying of building block that finishes of watering promptly makes the building block of finished product light-weight aggregate.
Preferably, among the above-mentioned light-weight aggregate building block preparation method, natural curing 28 days, or vapor cure is no less than 5 hours.
Preferably, among the above-mentioned light-weight aggregate building block preparation method, watering time is 7 days.
Preferably, among the above-mentioned light-weight aggregate building block preparation method, the processing condition of watering were watered once for every day first three day, watered every other day by the 7th day in the 4th day.
Advantage and positively effect that the present invention has are:
1, the present invention is being used as coarse aggregate through the later refuse clay brick of processing; The industrial residue liquid slag is as fine aggregate, and flyash adopts many particle diameters of thickness proportioning as stopping composition; The block structure of producing is tight, and each item performance index all meet the GB/T15229-2002 standard-required.
2, production technique is simple, and three-waste free discharge meets national energy-saving and emission-reduction, development low-carbon economy and circular economy policy, is a kind of energy-conservation, material-saving, sharp useless New Building Materials.
3, in this invention, the volume of waste resource reaches more than 80%, has solved the unmanageable problem of refuse clay brick, has not only protected environment but also practiced thrift the soil, and the comprehensive utilization ratio of refuse clay brick and liquid slag has been reached more than 96%.
