Abstract
The invention provides an autoclaved aerated concrete. Ingredients for the concrete comprise, by mass, 100 parts of lime, 10 to 30 parts of cement, 160 to 350 parts of fly ash, 0.06 to 0.6 part of aluminum powder and 0.2 to 0.8 part of EPS polyphenyl granules. The autoclaved aerated concrete provided in the invention improves compressive strength of aerated concrete, reduces the shrink rate of materials and effectively overcomes the problem of cracking besides maintaining original performance of aerated concrete.
Description
Technical field
The present invention relates to a kind of New Building Materials, a kind of specifically steam-pressing aero-concrete.
Background technology
At present, along with country about policy guidances such as " low-carbon (LC) ", " four joint one environmental protection ", carrying forward vigorously the wallboard innovation and promoting energy saving building has become inexorable trend.Building trade has been emerged in large numbers a large amount of non-clay goods materials for walls in banning use of the implementation process of clay brick, be exactly a kind of extraordinary clay substitute like gas concrete, but good working ability and heat insulation and insulated capacity are not only arranged, also environmental protection.But see that according to the existing market practical situations existing gas concrete is exactly that the gas concrete shrinking percentage is bigger because its composition material and production technique exist intrinsic deficiency, ultimate compression strength is low, is easy to generate cracking, influences wall performance.
Summary of the invention
Ultimate compression strength to above-mentioned existing concrete is lower, the material contracts rate is sent to, the deficiency of easy of crack; It is a kind of when guaranteeing the original performance of gas concrete that the present invention provides, and increases ultimate compression strength and reduce the material contracts rate, effectively solve the steam-pressing aero-concrete of cracking problem.
For realizing above-mentioned purpose, the technical scheme that the present invention adopts is:
A kind of steam-pressing aero-concrete, said concrete batching comprises lime, cement, flyash and aluminium powder, and said concrete batching also comprises the EPS granular polystyrene, and the ratio of quality and the number of copies of five kinds of components is: 100 parts in lime; 10 ~ 30 parts of cement; 160 ~ 350 parts in flyash; 0.06 ~ 0.6 part of aluminium powder; 0.2 ~ 0.8 part of EPS granular polystyrene.
Further, the ratio of quality and the number of copies of said five kinds of components is: 100 parts in lime; 20 ~ 25 parts of cement; 200 ~ 260 parts in flyash; 0.1 ~ 0.4 part of aluminium powder; 0.3 ~ 0.5 part of EPS granular polystyrene.
Further, said EPS granular polystyrene is the pellet that former germinal vesicle forms, the diameter≤5mm of said pellet, density 4 ~ 6kg/m
3
Technical conceive of the present invention is: prepare burden at traditional gas concrete: in lime, cement, flyash, the aluminium powder, as required, add a certain proportion of EPS granular polystyrene.Say that wherein the EPS granular polystyrene that adds is the pellet that former germinal vesicle forms, diameter≤5mm, density 4 ~ 6kg/m
3
In the existing gas concrete, aluminium powder produces great amount of bubbles as foam material, be evenly distributed in the concrete, but the concrete voidage after the moulding is big, and shrinking percentage is high, and ultimate compression strength is little, easy of crack.For this reason, the EPS granular polystyrene that is added just in time replaces the original space of part.On the basis of guaranteeing equal volume density, material contracts rate, ultimate compression strength aspect all obtain bigger change.But, if the EPS granular polystyrene that adds can influence concrete workability and volume density, and be less than 0.2 part of ultimate compression strength that directly influences finished product more than 0.8 part.
Compared with prior art; The beneficial effect that this invention brings is: this invention is increasing under the prerequisite that cost seldom drops into, and when guaranteeing the original performance of gas concrete, increases ultimate compression strength and reduces the material contracts rate; Solved gas concrete intensity low and shrink big, the deficiency of easy of crack.Applied widely, have good value for applications.
