；
It should be noted that its design of formula with innovation formula of above-mentioned first fiber concrete layer, in addition to using coal
Spoil powder, Emathlite, land plaster, cement, quartz sand powder, the formula such as alkali-resistant glass fibre that is chopped (pay attention to the alkaline-resisting glass that is chopped
Glass fiber can also pass through steel fibre or carbon fiber or chrysotile asbestos fibre, green stone cotton fiber, iron-stone cotton fiber, alkali resistant glass fibers
Carbon fibers such as dimension and alkali resistant mineral wool etc. are replaced), additionally using urban inorganic garbage powder, it clearly enhances construction material
Environmental-protection function；It also added brand-new design formula as nano-mineral modified mixed powder simultaneously, this is nano-mineral modified mixed
Can significantly the first fiber concrete layer progress performances such as intensity and anti-impact force, stress performance be improved by closing powder；It is above-mentioned
First fiber concrete layer shock resistance is good, and has many advantages, such as sound insulation, heat preservation, waterproof；Meanwhile aluminium hydroxide plays centainly
The fire retardation of degree.
It needs to be emphasized that urban inorganic garbage refers to the waste of inorganic constituents in domestic waste.This is useless
Gurry further includes some lightweight slag, clinkers etc. essentially from bottle, jar and other old metal and cullet for being packed for.City
City's inorganic refuse powder is then the floury structure substance being manufactured by the inorganic rubbish in city.Emathlite is also known as natural bleaching soil, i.e.,
The inherently carclazyte with bleachability of natural output is with montmorillonite, albite, quartz for the white, white of key component
Gray clay is bentonitic one kind.Emathlite is mainly the product after nature of glass volcanic rock decomposes, it is not swollen after absorbing water
It is swollen, find that the structural formulation as fiber concrete layer has the technique effect for being obviously improved water resistance by research.
The bubble concrete layer specific formula of the third layer composite layer is as follows：
The bubble concrete layer is mixed evenly by cementitious material, water and water-reducing agent, foaming agent；The gelling
Material is made of portland cement and fine coal ashes；Wherein each component ratio range is as follows：Portland cement 300-500kg/
m3；Fine coal ashes 100-150kg/m3；Water 150-210kg/m3；Water-reducing agent 2-4kg/m3；The water-reducing agent is polycarboxylic-acid solid
High efficiency water reducing agent；The foaming agent is specially the hydrogen peroxide solution of a concentration of 35-45%；The fine coal ashes is I grades of fine coal of F classes
Ash；
It should be noted that the second layer composite layer specifically includes defoaming agent carrier 21 (i.e. with the 4th layer of composite layer)；
The defoaming agent carrier 21 is netted (referring to Fig. 4)；
It should be noted that antifoaming agent good dispersion, defoaming in cement mortar system is rapid；It can effectively control water
Foam generates in silt particle slurry system, and alloing the finer and close light of concrete layer, (i.e. antifoaming agent changes foam surface tension and makes
Bubbles burst, to achieve the purpose that defoaming).It pours into a mould in the forming process after concrete grout, and impregnated in shaping mold cavity
The bubble overwhelming majority that the defoaming agent carrier of antifoaming agent is in direct contact is eliminated, and concrete grout is close at left and right sides of defoaming agent carrier
It spends larger, has been here formed as the fine and close hard thin layer with some strength, i.e. surface dense layer.Due near defoaming agent carrier
A part of bubble be also eliminated, therefore the density of concrete grout is also opposite improves.
Because being provided with defoaming agent carrier in concrete layer, and defoam agent carrier be it is netted (i.e. its substantially be exactly a piece of
Reticular structure), effect is adherency antifoaming agent；It will be fixed in shaping mold cavity, defoam immersed with the defoaming agent carrier of antifoaming agent
Agent can change foam surface tension and make bubbles burst, to achieve the purpose that defoaming.Then when concrete layer is molded
The both sides bubble overwhelming majority of defoaming agent carrier is eliminated and forms a thin layer of, the higher surface dense layer of intensity.
It when making, will be fixed in shaping mold cavity immersed with the defoaming agent carrier of antifoaming agent, after pouring into a mould concrete grout
In forming process, the bubble overwhelming majority being in direct contact with the defoaming agent carrier for impregnating antifoaming agent is eliminated, therefore is defoamed
The both sides of agent carrier just form the fine and close hard thin layer with some strength, i.e. surface dense layer.(in this way in foam concrete plate
It when moulding by casting, is eliminated with the bubble overwhelming majority for the forming panel face layer contacts for smearing antifoaming agent, the gas near the layer of face
A bubble part is eliminated, and has then just been formed about compacted zone on the surface of foam concrete.) therefore antifoaming agent combination antifoaming agent
The design of carrier will significantly play the role of defoaming, significantly promote the compactness of concrete layer, and it is strong to promote concrete layer
Spend index and quick-drying index.
