Abstract
The invention relates to a construction material, in particular to an ardealite concrete aerated block. The aerated block is prepared by mixing the following raw materials in percentage by weight: 40 to 51 percent of ardealite minerals, 15 to 25 percent of minerals with mass percentage of silicon dioxide of over 80 percent, 15 to 25 percent of limestone with mass percentage of calcium oxide of over 50 percent, 16 to 18 percent of quicklime, and 2 to 5 percent of cement. The ardealite is physically modified to prepare an energy-saving construction material, so that pollution of industrial solid wastes to the environment is reduced, mineral resources are effectively saved, and resource utilization is improved.
Description
Technical field
The present invention relates to a kind of material of construction, particularly a kind of phosphogypsum concrete aerated blocks.
Background technology
Phosphogypsum is that a kind of free water content is moist powder or the slurry of 10%-20%, and the pH value is 1.9-5.3, and color is based on grey.Phosphate fertilizer plant's one ton of phosphate fertilizer of every production can produce five tons of phosphogypsums.China's annual accumulative total casting phosphogypsum is more than 1,000,000,000 tons, and the application of phosphogypsum is a world-famous puzzle, and whole utilization ratio is less than 10%.
Contain phosphoric acid salt, vitriol, fluorochemical and heavy metal in the phosphogypsum, also have a spot of radium.If phosphogypsum does not utilize or do not stack in accordance with regulations, some objectionable impurities wherein can be water-soluble and be discharged into surrounding environment, makes underground and the face of land is subjected to serious pollution.If so a large amount of trade wastes is not sought application approach, will cause severe contamination and destruction to environment.So the purposes of inventing a kind of phosphogypsum, turning waste into wealth is highly profitable.The present invention is used to make concrete aerated blocks with phosphogypsum, recycles as material of construction.In the prior art, adopt various industrial wastes many as the aerated blocks material of construction, but the report that adopts phosphogypsum to make aerated blocks does not have then.Because the technician of building material field generally thinks phosphogypsum sulfur acid calcium than higher, and is siliceous few, be not suitable as the aerated blocks material of construction.
Summary of the invention
The present invention is exactly the defective at prior art, provides a kind of phosphogypsum concrete aerated blocks and manufacture method thereof, to remedy the deficiencies in the prior art.
For solving the problems of the technologies described above, the technical solution used in the present invention is: it is mixed by following raw materials by weight:
Phosphogypsum mineral substance 40-51%, silicon-dioxide quality percentage composition are higher than 80% mineral substance 15-25%, calcium oxide quality percentage composition and are higher than 50% Wingdale 15-25%, unslaked lime 16-18%, cement 2-5%.
The present invention's technical scheme preferably is: it is mixed by following raw materials by weight:

The better technical scheme of the present invention is: be added with aluminium powder in the described phosphogypsum concrete aerated blocks, wherein contain aluminium powder 500 grams in every cubic metre the phosphogypsum concrete aerated blocks.Add aluminium powder and can produce good foaming effect, reduce the density of phosphogypsum concrete aerated blocks.Described phosphogypsum mineral substance is that phosphate fertilizer plant produces the phosphogypsum waste material that phosphate fertilizer produces.
Production method of the present invention is: mixed by following raw materials by weight: phosphogypsum mineral substance 40-51%, silicon-dioxide quality percentage composition are higher than 80% mineral substance 15-25%, calcium oxide quality percentage composition and are higher than 50% Wingdale 15-25%, unslaked lime 16-18%, cement 2-5%, and it may further comprise the steps:
(1), phosphogypsum mineral substance, silicon-dioxide quality percentage composition are higher than 80% mineral substance, calcium oxide quality percentage composition are higher than 50% Wingdale and add the water mixing and stirring, obtain mineral mixture;
(2), cement is injected mineral mixture and obtain the mineral water sludge mixed material;
(3), unslaked lime injected the mineral water sludge mixed material stirred 3-5 minute, the aluminium powder that reinjects stirs 30-40 second, heats up in the time of stirring, pours into a mould at 38-45 °; Too high or too low for temperature, the intensity of product does not reach requirement.
(4), carry out after pouring quietly stopping, cutting;
(5), cut the back in steam-cured still under 180 ℃, the pressure of 1.3MPa, with steam steam-cured 8-9 hour.Back intensity 〉=2.8 are frozen in product ultimate compression strength 〉=3.5 of Sheng Chaning with this understanding.
The present invention's production method preferably is: it is mixed by following raw materials by weight: phosphogypsum mineral substance 40%, silicon-dioxide quality percentage composition are higher than 80% mineral substance 20%, calcium oxide quality percentage composition and are higher than 50% Wingdale 20%, unslaked lime 17.3%, cement 2.7%.
The present invention makes energy saving building material by phosphogypsum is carried out physical modification, has not only reduced the industrial residue pollution on the environment, and has saved Mineral resources effectively, has improved resource utilization.The frost resistance and the intensity of the phosphogypsum concrete aerated blocks that the inventive method is produced are higher than standard GB 11968-2006[autoclave aerated concrete building block far away].
