Description
Technical field
The present invention relates to steam-pressing aero-concrete production field more particularly to a kind of high-strength autoclaved aerated coagulations of low unit weight
The preparation method of earth building blocks.
Background technology
Autoclave aerated concrete building block is using calcareous material and siliceous material as base stock, is material of getting angry with aluminium powder,
The porous structure formed in such a way that chemical reaction is got angry forms adapt to market demands with certain specification after cutting, passes through steam pressure
Maintenance obtains the artificial stone material of lightweight of physical strength.
It is formed from Macroscopic physical, it has the air hole structure of a large amount of fine uniforms, illustrates that it belongs to celluar concrete one
Class, from the point of view of the hydration reaction and product between its basic composition material and these materials, it belongs to silicate concrete,
From the point of view of it obtains the method for intensity, it belongs to steam press maintenance product, and from the point of view of the method that its porous structure is formed, it belongs to material
Expect component between by chemical reaction generate gas, that is, so-called " aerating " rather than therefore additional foam is steam pressurized coagulation
Earth building blocks are also aerated bricks.
Currently, the autoclave aerated concrete building block of domestic volume production is B04~B07 grades, B02 grades of products are just to have risen in China
Step section, domestic there are no manufacturers to reach volume production ability.
In view of the foregoing, a kind of preparation method of low unit weight high-strength autoclaved aerated concrete building block is now developed.
Invention content
Purpose of the invention is to overcome the shortcomings in the prior art, and it is high-strength autoclaved aerated mixed to provide a kind of low unit weight
The preparation method of solidifying earth building blocks is researched and developed low A1.0B02 grades of products of unit weight autoclave aerated concrete building block using glass tailing, is filled up
Blank of the China in terms of low unit weight product increases Products popularity, occupation rate on the market.
The present invention to achieve the goals above, adopts the following technical scheme that：A kind of high-strength autoclaved aerated coagulation of low unit weight
The preparation method of earth building blocks, process flow steps are：Slurrying → grinding → cast → cutting → steam-cured；
Slurrying：Glass tailing and gypsum, water are stirred evenly in proportion, spare slurry is made；Glass tailing and gypsum
Weight percent is：Glass tailing：96~98%, gypsum：1.1~4.7%, the sum of the weight that assembles of glass tailing and gypsum is
100%, the ratio of the mixture and water of glass tailing and gypsum is：1:2.3~2.6；
Grinding：Lump lime is levigate, and fineness meets 0.08 square hole screen and tails over≤15%；
Cast：Spare slurry and powdery quick lime, cement are stirred evenly in proportion as mixed slurry, spare slurry with
Powdery quick lime, cement ratio be：1:0.45~0.55：0.7~0.8, and mixed slurry temperature is made to be increased to 38~42 °,
Being proportionally added into aluminum powder solution becomes the mixture of liquid phase shape, and the ratio of mixed slurry and aluminum powder solution is：1:0.06~0.09,
After stirring 25~35 seconds, inject mold, the mixture of liquid phase state passes through 25~35 minutes, aluminium powder under alkaline environment with
Medium water is reacted, and hydrogen is generated so that and liquid phase has air hole structure, meanwhile, quick lime is reacted with water, is released heat, is made liquid phase
Thickening, gradually forms green body；
Cutting：Green body is cut into the green body of specified specification on cutting machine；
It is steam-cured：Will well cutting green body organize into groups after be put into still kettle, through 10~12 hours, carry out hydrothermal exchange and anti-
It answers, forms silicate product, A1.0B02 grades of finished products are made after going out kettle.
The beneficial effects of the invention are as follows：Low A1.0B02 grades of unit weight autoclave aerated concrete building block is researched and developed using glass tailing
Product, lighter than existing B04~B07 grades of weight, every cube of weight is less than 225 kilograms, can do thermal insulation decorative material, from
Heat preservation thin plate pastes on constructional column, plays the role of heat-insulating sound-insulating, effectively prevent heat bridge phenomenon；The present invention has filled up China low
Blank in terms of unit weight product increases Products popularity, occupation rate on the market.
Specific implementation mode
With reference to embodiment, invention is further described in detail with specific implementation mode：
Embodiment 1
Slurrying：Glass tailing and gypsum, water are stirred evenly in proportion, spare slurry is made；Glass tailing and gypsum
Weight percent is：Glass tailing：97%, gypsum：3%, the sum of the weight that assembles of glass tailing and gypsum is 100%, glass
The ratio of the mixture and water of tailing and gypsum is：1:2.5；
Grinding：Lump lime is levigate, and fineness meets 0.08 square hole screen and tails over≤15%；
Cast：Spare slurry and powdery quick lime, cement are stirred evenly in proportion as mixed slurry, spare slurry with
Powdery quick lime, cement ratio be：1:0.47：0.7, and mixed slurry temperature is made to be increased to 40 °, it is molten to be proportionally added into aluminium powder
Liquid becomes the mixture of liquid phase shape, and the ratio of mixed slurry and aluminum powder solution is：1:0.08, after stirring 30 seconds, inject mold, liquid
