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 constructional materials, particularly a kind of ardealite concrete aerated blocks.
Background technology
Ardealite 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 main with grey.Phosphate fertilizer plant's one ton of phosphate fertilizer of every production can produce five tons of ardealites.China's annual accumulative total casting ardealite is more than 1,000,000,000 tons, and the application of ardealite is a world-famous puzzle, and whole utilization rate is less than 10%.
Contain phosphate, sulfate, fluoride and heavy metal in the ardealite, also have a spot of radium.If ardealite does not utilize or stack not according to regulation, some hazardous substances wherein can be water-soluble and be discharged into surrounding environment, makes undergroundly to receive serious pollution with the face of land.If so a large amount of trade wastes is not sought application approach, will cause severe contamination and destruction to environment.The purposes of therefore inventing a kind of ardealite, turning waste into wealth is highly profitable.The present invention is used to make concrete aerated blocks with ardealite, recycles as constructional materials.In the prior art, adopt various industrial wastes many as the aerated blocks constructional materials, but the report that adopts ardealite to make aerated blocks does not have then.Because the technician of building material field generally thinks ardealite sulfur acid calcium than higher, and is siliceous few, be not suitable for as the aerated blocks constructional materials.
Summary of the invention
The present invention is exactly the defective to prior art, a kind of ardealite concrete aerated blocks and manufacturing approach thereof is provided, to remedy the deficiency of prior art.
For solving the problems of the technologies described above, the technical scheme that the present invention adopts is: it is mixed by following raw materials by weight:
Ardealite mineral matter 40-51%, silica quality percentage composition are higher than 80% mineral matter 15-25%, calcium oxide quality percentage composition and are higher than 50% limestone 15-25%, quicklime 16-18%, cement 2-5%.
The present invention's technical scheme preferably is: it is mixed by following raw materials by weight:
Ardealite mineral matter 40%, silica quality percentage composition are higher than 80% mineral matter 20%, calcium oxide quality percentage composition and are higher than 50% limestone 20%, quicklime 17.3%, cement 2.7%.
The better technical scheme of the present invention is: be added with aluminium powder in the described ardealite concrete aerated blocks, wherein contain aluminium powder 500 grams in every cubic metre the ardealite concrete aerated blocks.Add aluminium powder and can produce good foaming effect, reduce the density of ardealite concrete aerated blocks.Described ardealite mineral matter is that phosphate fertilizer plant produces the ardealite waste material that phosphate fertilizer produces.
Production method of the present invention is: mixed by following raw materials by weight: ardealite mineral matter 40-51%, silica quality percentage composition are higher than 80% mineral matter 15-25%, calcium oxide quality percentage composition and are higher than 50% limestone 15-25%, quicklime 16-18%, cement 2-5%, and it may further comprise the steps:
(1), ardealite mineral matter, silica quality percentage composition are higher than 80% mineral matter, calcium oxide quality percentage composition are higher than 50% limestone 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), quicklime 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 the steam-cured 8-9 of steam hour.Back intensity >=2.8 are frozen in product compressive strength >=3.5 that produce with this understanding.
The present invention's production method preferably is: it is mixed by following raw materials by weight: ardealite mineral matter 40%, silica quality percentage composition are higher than 80% mineral matter 20%, calcium oxide quality percentage composition and are higher than 50% limestone 20%, quicklime 17.3%, cement 2.7%.
The present invention processes energy saving building material through ardealite is carried out physical modification, has not only reduced the industrial residue pollution on the environment, and has practiced thrift mineral resources effectively, has improved resource utilization.The frost resistance and the intensity of the ardealite concrete aerated blocks that the inventive method is produced are higher than standard GB 11968-2006 [Autoclaved aerated concrete blocks] far away.
