Description
Technical field
The present invention relates to a kind of for building component and the proportioning of the packing material of filled wall or floor, particularly packing material.
Background technology
Building infilled wall and floor are the enclosed structures of buildings, measure the performances such as large and wide, its sound insulation, heat insulation, intensity, fire prevention, protection against the tide, waterproof, use properties and safety performance that directly impact is built.Along with the progress in epoch and the requirement of environmental protection, the epoch of Qin brick and Han tile finish already, and new wall material is constantly released, and at present, aerated concrete building block is more as infilled wall, and hollow steel framework at center cement metal mesh interior partition wall is also widely adopted.
But above-mentioned infilled wall is also deposited also in following problem: first, along with the shortage of China's manpower, labour cost is multiplied, and logistics cost improves constantly, corresponding the having a more substantial increase of cost of infilled wall; Secondly, traditional floor is generally the reinforced concrete thin plate of 80～100mm, its soundproof effect is not good, energy-efficient performance is bad, can not be thereon partition wall arbitrarily, thereby limited the handiness of using; Also have, the intensity of aerated concrete building block infilled wall is lower be unfavorable for security and whitewash, its deadweight improves agent structure cost compared with conference, the poor structural seismic that is unfavorable for of globality, and the complicated construction technique of hollow steel framework at center cement metal mesh interior partition wall makes the duration corresponding longer.Especially, the materials of above-mentioned filled wall, no matter be cement concrete or other material, the cost of its stopping composition as body of wall or floor own is all very high, adds concrete setting time longer, necessary improvement.
In sum, the packing material cost that traditional infilled wall is used is high, and labour cost is high, and the construction period is long, and wall performance controllability (being handiness) is poor.Therefore, a kind of building infilled wall of necessary research and development, its filling materials for wall body Costco Wholesale is low, applied widely, and easy construction is simple, and body of wall overall quality is good.Along with deepening continuously of Sustainable development idea; industrial waste, as the comprehensive utilization of phosphogypsum, desulfurated plaster, fluorgypsum, building waste etc. starts to come into one's own, because this class materials'use cost is extremely low, is conducive to again protection of the environment; can turn waste into wealth, meet the values of Sustainable development.In addition; if packing material utilizes native industry waste material and rubbish to suit measures to local conditions to concentrate mass-producing preparation; site operation mechanized operation; so, can expect and reach the object that a large amount of savings are artificial, reduce logistics, reduction of erection time, reduction cost, raising performance, protection of the environment, Sustainable development.
Phosphogypsum or desulfurated plaster, as the byproduct of Chemical Manufacture, normally according to offal treatment, do not have to make full use of its value.And the main component of phosphogypsum or desulfurated plaster is exactly dihydrate gypsum, dihydrate gypsum (CaSO
42H
2o) be called again plaster stone, through calcining, the levigate beta-type semi-hydrated gypsum (CaSO that obtains
41/2H
2o), plaster of Paris, claims again the plaster of Paris, plaster.Semi-hydrated gypsum, as conventional material of construction, is characterized in having good activity, fast solidifying, and plasticity-is good, and intensity is high, is good gelling material.But semi-hydrated gypsum but has larger defect as the packing material of infilled wall, major cause is that it solidifies comparatively fast, conventionally at 3～5 minutes, just solidify, the short like this time is impossible for a large amount of, large-area construction because material also not casting complete just solidified.Although can add synthetic retardant slack time, the price of retardant own is just very high, configure also cumbersome, if a large amount of uses, the inevitable significantly rising of cost.
By above-mentioned analysis, know, semi-hydrated gypsum is good Filled-wall material, and its use cost has great advantage, if can take it as gelling base-material, adds suitable auxiliary material and improves its setting time, and this packing material has very high promotional value so.
