Abstract
A kind of construction process of compound autoclave aerated concrete building block body of wall, it is characterized in that, described compound autoclave aerated concrete building block body of wall is bonded by compound autoclave aerated concrete building block adhesive specially by compound autoclave aerated concrete building block, paraffin in the present invention inside moulding box melts and penetrates in concrete segment body in drying room, enhance building block entirety every wet water resistance, glass fibre is because initial setting up is in building block outside, position inside moulding box, thawing part along with paraffin is infiltrated in the middle of building block, part extends building block body, like this, when this building block is for building, submerge glass fibre another part of building block of part can submerge in the middle of the tackiness agent of blockhouse, strengthen the bond strength between building block body and tackiness agent further, thus enhance the bulk strength of the building that building block building becomes.
Description
Technical field
The present invention relates to a kind of preparation method of compound autoclave aerated concrete building block, belong to field of constructional engineering material.
Background technology
Compound autoclave aerated concrete building block is a kind of brand-new material of building field.It utilizes and adds aluminium powder in the batching of calcareous material (as cement, lime) and siliceous material (as sand, flyash, slag) and make air entraining agent, through the stirring that adds water, casting, expansion of getting angry, precuring cutting, then form porous silicate building block through autoclave curing.Make it have sound insulation because of the porous material of this building block, quality is light, and the features such as resistance to pressure is good, and heat retaining property is excellent, its processibility is also very good, even can carry out cutting processing as blockishness saw.Therefore, this material is at present in the favorable substitutes of the widely used solid fragment of brick of building field.
In recent years, spirit that the General Office of the State Council has issued " about advancing materials for wall innovation further and promoting the notice of energy saving building " (Office of the State Council is sent out [2005] No. 33), National Development and Reform Commission, Ministry of Land and Resources, the Ministry of Construction, the Ministry of Agriculture dispatch a joint document " prohibitting the use solid clay brick to claim the notice of city list in limited time about announcement second batch " (send out and change No. [2005] 2656, ring money).Country is in the regulation of " progressively prohibitting the use solid clay brick in limited time in dwelling construction ".The market outlook of this product are huge, have great economic worth.
But although this compound autoclave aerated concrete building block has above-mentioned excellent technical feature and economic worth, this product still exists many defects urgently to be improved.Because its porosity and looseness causes its water absorbability and water-absorbent strong all in the extreme, when this concrete segment is in long-term alternation of wetting and drying, this concrete segment is easy to occur cracking, the phenomenon come off.The water absorbability of concrete segment also by the moisture absorption in the middle of outside air, and slowly can penetrate into indoor, increases indoor humidity, brings very large difficulty to air-conditioning system dehumidifying.With regard in this meaning, although compound autoclave aerated concrete building block has excellent heat insulation performance, its water-resistant capacity, all bad every wet ability, this greatly limits the range of application of this type material.
In addition, occurred in the middle of prior art much in concrete segment, adding filamentary material to form the improvement project of matrix material.But these schemes all have ignored for building body, the part that its intensity is the weakest is the bond site between building block, no matter how firm building block is, if the combining site undertighten of blockhouse, still intensity is very poor for the building body of its entirety.If to add matrix material to block interiors be unusual poor efficiency and uneconomic, a large amount of expensive filamentary material can be wasted.
Summary of the invention
Goal of the invention: the object of the present invention is to provide a kind of water-resistant capacity strong, every the compound autoclave aerated concrete building block that wet ability is strong.
Technical scheme: the preparation method of compound autoclave aerated concrete building block of the present invention, this compound autoclave aerated concrete building block comprises the component of following parts by weight: described compound autoclave aerated concrete building block is made up of following raw material: 60 ~ 72 parts, flyash, 10 ~ 15 parts, lime, 5 ~ 9 parts, gypsum, cement 5 ~ 7 parts, aluminium powder 0.1 ~ 1 part, 3 ~ 7 parts, paraffin, and glass fibre 0.1 ~ 5 part of preparation process is as follows:
(1) raw material except paraffin and glass fibre is added the water grinding of 80 ~ 100 parts of parts by weight, after stirring, make equal chylema;
(2) fully stirring adding glass fibre after paraffin melting, being then coated to the internal surface of moulding box, for subsequent use after paraffin;
(3) equal chylema step (1) prepared leaves standstill 10 ~ 20 minutes, is poured in the moulding box that step (2) obtains after supernatant liquid to be removed;
(4) moulding box of (3) in step is sent in drying room; Adjustment drying room temperature, makes drying room keep precuring temperature 52 ~ 70 degrees Celsius 1 ~ 3 hour, namely obtains building block embryo after precuring terminates;
(5) after building block embryo surface parches, described compound autoclave aerated concrete building block is namely obtained.
Further, the component of described compound autoclave aerated concrete building block also comprises the suds-stabilizing agent of parts by weight 1.5 ~ 4 parts.
Further, ridge design is provided with inside described moulding box.
The present invention compared with prior art, its beneficial effect is: the paraffin inside moulding box melts and penetrates in concrete segment body in drying room, enhance building block entirety every wet water resistance, glass fibre is because initial setting up is in building block outside, position inside moulding box, thawing part along with paraffin is infiltrated in the middle of building block, part extends building block body, like this, when this building block is for building, submerge glass fibre another part of building block of part can submerge in the middle of the tackiness agent of blockhouse, strengthen the bond strength between building block body and tackiness agent further, thus enhance the bulk strength of the building that building block building becomes.
