Be equivalent to the dibutyl maleate of powder body weight 1-2%, 1-2% chlorinated paraffin agitating uniform, dry, be ground into powder i.e.
?；
It should be noted that above-mentioned first its formula of fiber concrete layer has the design of innovation formula, except have employed coal
Spoil powder, Emathlite, Gypsum Fibrosum powder, cement, quartz sand powder, the formula such as chopped alkali-resistant glass fibre (notes the alkaline-resisting glass of this chopped
Glass fiber can also be by steel fibre or carbon fiber or chrysotile asbestos fibre, blue asbestos fiber, amosite fiber, alkali resistant glass fibers
The carbon fibers etc. such as dimension and alkali resistant mineral wool are replaced), it clearly enhances construction material to additionally use urban inorganic garbage powder
Environmental-protection function；It also added nano-mineral modified mixed powder such brand-new design formula simultaneously, and this is nano-mineral modified mixed
Conjunction powder significantly the first fiber concrete layer can be carried out intensity and the performance such as anti-impact force, stress performance improves；Above-mentioned
First fiber concrete layer shock resistance is good, and has sound insulation, insulation, the advantage such as waterproof；Meanwhile, aluminium hydroxide plays necessarily
The fire retardation of degree.
Need especially it is emphasized that urban inorganic garbage refers to the garbage of inorganic constituents in domestic waste.This gives up
Gurry, essentially from bottle, jar and other wrapping old metal and cullet, also includes some lightweight slag, slags etc..City
City's inorganic refuse powder is then the floury structure material being manufactured into by the inorganic rubbish in city.Emathlite is also known as natural bleaching soil, i.e.
The hargil inherently with bleachability of natural output, is with montmorillonite, albite, the quartz white as key component, white
Gray clay, is bentonitic one.Emathlite is mainly the product after nature of glass volcanic rock decomposes, the most swollen after its water suction
Swollen, find to have the technique effect being obviously improved water resistance as the structural formulation of fiber concrete layer through research.
The concrete formula of bubble concrete layer of described third layer composite bed is as follows:
Described bubble concrete layer is formed by Binder Materials, water and water reducer, foaming agent mixing and stirring；Described gelling
Material is made up of portland cement and fine coal ashes；The most each component ratio scope is as follows: portland cement 300-500kg/
m3；Fine coal ashes 100-150kg/m3；Water 150-210kg/m3；Water reducer 2-4kg/m3；Described water reducer is polycarboxylic-acid solid
High efficiency water reducing agent；Described foaming agent specially concentration is the hydrogen peroxide solution of 35-45%；Described fine coal ashes is F class I level fine coal
Ash；
It should be noted that described second layer composite bed (i.e. with the 4th layer of composite bed) specifically includes defoamer carrier 21；
Described defoamer carrier 21 is netted (seeing Fig. 4)；
It should be noted that defoamer good dispersion, froth breaking in cement mortar system is rapid；It can effectively control water
In cement mortar system, foam produces, and (i.e. defoamer can change foam surface tension force and make to make the finer and close light of concrete layer
Bubbles burst, thus reach the purpose of froth breaking).Shaping mold cavity is poured into a mould in the forming process after concrete grout, and soaked
The bubble overwhelming majority that the defoamer carrier of defoamer directly contacts is eliminated, and defoamer carrier left and right sides concrete grout is close
Degree is relatively big, has been here formed as the fine and close hard thin layer with some strength, i.e. surface compact layer.Due near defoamer carrier
A part of bubble be also eliminated, therefore the density of concrete grout improves the most relatively.
Because being provided with defoamer carrier in concrete layer, and defoamer carrier is that netted (i.e. its essence is exactly a piece of
Network structure), its effect is to adhere to defoamer；Defoamer carrier immersed with defoamer is fixed in shaping mold cavity, froth breaking
Agent can change foam surface tension force and make bubbles burst, thus reaches the purpose of froth breaking.Then when concrete layer molding
Surface compact layer that the both sides bubble overwhelming majority of defoamer carrier is eliminated and forms thin layer, that intensity is higher.
When making, the defoamer carrier immersed with defoamer is fixed in shaping mold cavity, after cast concrete grout
In forming process, the bubble overwhelming majority directly contacted with the defoamer carrier soaking defoamer is eliminated, therefore froth breaking
The both sides of agent carrier are formed for the fine and close hard thin layer with some strength, i.e. surface compact layer.(so at foam concrete plate
During moulding by casting, it is eliminated with the bubble overwhelming majority of the forming panel face layer contacts smearing defoamer, the gas near surface layer
A bubble part is eliminated, and the most just the near surface at foam concrete defines compacted zone.) therefore defoamer combine defoamer
The effect of froth breaking will be significantly played in the design of carrier, promotes the compactness of concrete layer significantly, promotes concrete layer strong
Degree index and quick-drying index.
The second concrete formula of fiber concrete layer of described layer 5 composite bed is as follows:
Described second fiber concrete layer is in terms of mass fraction: described second fiber concrete layer includes industrial aluminum sulphate 7-

Material, selecting waterglass or sodium carbonate is inorganic water reducer raw material；By above-mentioned raw materials weight ratio respectively according to organic water reducer: inorganic
Water reducer be 1～3: 1～3 proportioning carry out configuring and pass through ball milling mix homogeneously, prepare brand-new compound diminishing formula.
It should be noted that the second fiber concrete layer of above-mentioned layer 5 composite bed have employed brand-new formula design,
This second fiber concrete layer has obvious structure stress specific aim；Second fiber concrete layer of this layer 5 composite bed,
There is good anticracking ability, simultaneously few with water, reduce the wasting of resources, and good fluidity, deform little.The work of above-mentioned blast-furnace cinder
Weight capacity with the second fiber concrete layer that can further enhance layer 5 composite bed；So-called blast-furnace cinder, the most all
During the blast furnace process pig iron, be able to silicate and aluminosilicate are the fused mass of main component, after quenching granulating, are granulation
Blast-furnace cinder (hereinafter referred to as slag)；It is fine that second fiber concrete layer of above-mentioned layer 5 composite bed is also mixed with high-strength imitative steel wire
Dimension, siderite, the formula such as diatom ooze；The most high-strength imitative steel wire fibre and siderite can strengthen layer 5 composite bed further
The structural strength of the second fiber concrete layer；Wherein, diatom ooze can promote the cracking resistance degeneration energy of the second fiber concrete layer.
The main raw material(s) of diatom ooze be go through 1 years formed diatom mineral kieselguhr, diatom be one way of life in ocean,
