Abstract
The invention discloses autoclaved aerated concrete which comprises the following components in parts by mass 100-150 parts of quartz sand, 70-100 parts of lime, 10-30 parts of cement, 0.06-0.6 part of aluminite powder, and 0.1-3 parts of silane coupling agent. The autoclaved aerated concrete, provided by the invention has the advantages of increasing the compressive strength and reducing the material shrinkage rate when ensuring the original performance of the aerated concrete, and effectively solving the crack problem.
Description
Technical field
The present invention relates to a kind of New Building Materials, specifically a kind of 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 such as 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 larger because its composition material and production technique exist intrinsic deficiency, ultimate compression strength is low, produces easily cracking, affects wall performance.
Summary of the invention
Ultimate compression strength for above-mentioned existing concrete is lower, material contracts rate deficiency large, that ftracture easily, the invention provides a kind ofly when guaranteeing the original performance of gas concrete, increase ultimate compression strength and reduce the material contracts rate, effectively solve the steam-pressing aero-concrete of problem of Cracking.
For achieving the above object, the technical solution used in the present invention is:
A kind of steam-pressing aero-concrete, described concrete batching comprises quartz sand, lime, cement and aluminium powder, and described concrete batching also comprises silane coupling agent, and the ratio of quality and the number of copies of each component is: quartz sand: 100 ~ 150 parts; Lime: 70 ~ 100 parts; Cement: 10 ~ 30 parts; 0.06 ~ 0.6 part of aluminium powder; Silane coupling agent: 0.1 ~ 3 part.
Further, described silane coupling agent is that the ratio of quality and the number of copies of described each component of solution is: silane: 100 parts take water and the pure solution that is mixed with as solvent; Alcohol: 500 ~ 800 parts; Water: 30 ~ 200 parts.
Technical conceive of the present invention is: at traditional aeroconcrete proportioning: in quartz sand, lime, cement, the aluminium powder, as required, add the silane coupling agent of preset proportion.
In the existing gas concrete, aluminium powder produces a large amount of bubbles as foam material, be evenly distributed in the concrete, but the concrete voidage after the moulding is large, and shrinking percentage is high, and ultimate compression strength is little, easily cracking.For this reason, the silane coupling agent that adds can remedy defects.On the basis of guaranteeing equal volume density, material contracts rate, ultimate compression strength aspect all obtain larger change.
Compared with prior art, the beneficial effect that this invention brings is: this invention is increasing under the prerequisite that seldom cost 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 large, the easy deficiency of cracking.Applied widely, have good value for applications.
