Abstract

The invention discloses a light aggregate building block prepared from a waste aerated concrete building block and a manufacturing method thereof. The light aggregate building block comprises the following components in parts by weight: 15-20 parts of waste aerated block particles, 33-39 parts of slag, 25-30 parts of liquid slag, 4-7 parts of fly ash, 13-18 parts of cement and 4-6 parts of water. The preparation method comprises the following major process steps of: mixing raw materials; press molding; maintaining; watering; standing; and drying. The light aggregate building block has the beneficial effects that: on the premise of meeting a compression resistance standard, the volume weight is effectively lowered, wastes are utilized effectively, and production cost is low.

Description

Light-weight aggregate building block that the useless air-entrained concrete building block of a kind of usefulness is processed and preparation method thereof
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 light-weight aggregate building block that the useless air-entrained concrete building block of a kind of usefulness processes and preparation method thereof.
Background technology:
Development along with the high stratification of urban architecture; The light block that is used for filled wall has obtained development rapidly; Since light block many with haydite, slag, slag for gathering materials, these raw-material demands significantly increase, and make the also rising gradually of production cost of manufacturer.While is along with the quickening of urban construction and urban renewal; Air-entrained concrete building block as a kind of light-weight materials for wall by a large amount of production and use; But in the process of producing and using; Produced a large amount of waste materials and unacceptable product, around the floor during these waste materials are deposited in plant area and build, the environment around not only having taken a large amount of soils but also having polluted.
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 light-weight aggregate building block that the useless air-entrained concrete building block of a kind of usefulness processes and preparation method thereof.
The technical scheme that the present invention adopts is:
The invention provides the light-weight aggregate building block that the useless air-entrained concrete building block of a kind of usefulness is processed, the parts by weight of its feed composition and each component are: useless air-entrained concrete building block: 15~20 parts; Slag: 33~39 parts; Liquid slag: 25~30 parts; Flyash: 4~7 parts; Cement: 13~18 parts; Water: 4~6 parts.
Preferably, in the above-mentioned light-weight aggregate building block raw material, said useless air-entrained concrete building block is that unit weight is 600Kg/m 3~700Kg/m 3, particle diameter is the useless air-entrained concrete building block of 2~5mm.
Preferably, in the above-mentioned light-weight aggregate building block raw material, said slag for meet " GB/T17431.1-98 ", particle diameter is the slag 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 is for meeting 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.
The preparation method of the light-weight aggregate building block that the useless air-entrained concrete building block of a kind of usefulness is processed, 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.
The beneficial effect that the present invention had:
1, the light-weight aggregate building block that utilizes useless air-entrained concrete building block, slag, liquid slag to produce, unit weight can drop to 700-770kg/m 3About, each item performance index all can reach standard GB/T15229-2002 requirement simultaneously.
2, the light-weight aggregate building block that utilizes useless air-entrained concrete building block, slag, liquid slag to produce; Because the holllow building block that volume to weight ratio is general is low, thus the part freight charges can be saved, and can effectively alleviate the deadweight of buildings; Reduce basis and structure and knock down, improved the shock resistance of buildings.
3, gather materials on the spot, sharp useless environmental protection, meet the energy-conservation industry policy of national environmental protection, pollution-free, the production zero release of this invention, trade waste capable of using, can enjoy government's relevant policies preferential with subsidize.
4, the mode of production is simple flexibly, and is easy to implement.
