Description
Technical field
The present invention relates to air entrained concrete technical fields, and in particular to a kind of physical blowing porcelain powder air entrained concrete and its life
Production. art.
Background technique
Air entrained concrete is to be with siliceous material (sand, flyash and containing silicon tailings etc.) and calcareous material (lime, cement)
Primary raw material adds foaming agent (aluminium powder), by ingredient, stirs, pours, precuring, cutting, steam pressure, the technical process system such as maintenance
At light porous silicate product.Air entrained concrete has that bulk density is light, thermal insulation property is high, sound-absorbing effect is good, has certain
The advantages that intensity and machinability is that China promotes and applies earliest, one of most popular light wall material.
Traditional process for producing aerated concrete is used frequently with the production technology of " chemical blowing " air entrained concrete
Raw material in contain aluminium powder, water, cement, gypsum, lime, fine coal or sand-lime;The production technology of traditional air entrained concrete produces
Though air entrained concrete can meet the requirement of building, have many advantages, such as sound-absorbing, heat-insulated, fire prevention, from heavy and light, built in current frame
It being widely used in building structure, but it uses aluminium powder to foam in process of production, there are security risks for itself, and
Mineral resources are more and more shorter in recent years, and environmental protection policy is increasingly stringenter, and influence maximum former material to product quality in the industry
Expect that " lime " source of goods is more and more nervous, the exploitation of stone for producing lime is limited, and firing, the live dust pollution of grinding are serious, faces
It shuts down, various reasons lead to lime quality worse and worse, and price increasingly increases, and coal-burning boiler is halted in environmental protection in addition, day
Right gas is at high price, so that many enterprises can't bear the heavy load, face and stop doing business.
Summary of the invention
The object of the present invention is to provide a kind of safe and environment-friendly and in short supply without using " lime " this source of goods physical blowing porcelain
Powder air entrained concrete and its production technology.And in the past few years as the cancellation of environmental requirement steam power plant is shut down, flyash is also at a
This industry commodity in short supply." porcelain powder " is found in finding material, is polished in production for Building Ceramics Industry, is cut workshop section
Generated industrial residue, dioxide-containing silica are greater than 70%, traditional flyash or silicon can be replaced completely husky.
A kind of physical blowing porcelain powder air entrained concrete, the raw material including following weight parts: 45-55 parts of water, cement 110-150
Part, 250-350 parts of porcelain powder, 0.8-1.2 parts of foaming agent, 2-4 parts of external additive.
Further, the physical blowing porcelain powder air entrained concrete, the raw material including following weight parts: 46-50 parts of water, water

Further, the foaming agent is foam concrete foamer.
Foam concrete foamer can exactly make its aqueous solution in the case where mechanicals efforts introduce air, generate a large amount of
One substance of foam, this substance are exactly surfactant or surface reactive material, the former is such as anion surface active
Agent, nonionic surfactant etc., the latter such as animal protein, vegetable protein, spent pulping liquor etc., foam concrete foamer, again
Name cement blowing agent, foam concrete foamer, which refers to, can reduce surface tension of liquid, generate a large amount of uniform and stable bubbles
Foam, to produce the additive of foam concrete.Foam concrete foamer used in the present invention can be with are as follows: anionic surface
Active agent formulation foaming agent, nonionic surfactant type foaming agent, protein active object type foaming agent etc..
Further, the external additive is made of following raw materials: diethylene glycol (DEG), malt sugar, glycerine, triethanolamine, anhydrous
Sodium sulfite, water.
Further, the external additive is made of the raw material of following weight parts: 8-15 parts of diethylene glycol (DEG), 15-20 parts of malt sugar,
12-15 parts of glycerine, 6-9 parts of triethanolamine, 18-25 parts of anhydrous sodium sulfite, 25-35 parts of water.
The addition of external additive has been catalyzed the coagulation of cement and aggregate, shortens the time of maintenance, enhances product
Intensity.
It is calcareous that a kind of physical blowing porcelain powder air entrained concrete of the present invention eliminates " lime ", " gypsum " in raw material
Material (resource of these calcareous materials is increasingly in short supply, and quality gradually declines), with cement for main cementitious material, and at this
It invents added with external additive in a kind of physical blowing porcelain powder air entrained concrete, external additive here functions as catalyst
Effect, can accelerate the condensation of cement Yu remaining aggregate, and then enhance the intensity of product, and can be shortened curing time, saving at
This.
In addition, in a kind of physical blowing porcelain powder air entrained concrete of the present invention added with foaming agent using foaming machine to its into
Traditional technique that aluminium powder foaming is added has been abandoned in row foaming, safer in the production process.
A kind of production technology of the physical blowing porcelain powder air entrained concrete, comprising the following steps:

(3) steam curing is carried out to slurry and obtains the physical blowing porcelain powder air entrained concrete.
Foaming machine also known as foam maker are a kind of foaming agent is reached foam made of certain density aqueous solution to set
Standby, foaming agent itself is cannot to automatically become foam, it is necessary to could become foam by the mechanism of foaming machine.Its work is former
Reason are as follows: introduce air into the solution of foaming agent.
Further, in step (2), the speed of the mixing is 100-120r/min, and the time of mixing is
10-15min, static 3-5min obtains slurry after to be mixed.
Further, in step (3), the steam curing are as follows: in the condition that temperature is 75-110 DEG C, pressure is normal pressure
Under, steam curing 5-9h.
The invention has the benefit that it is main that a kind of physical blowing porcelain powder air entrained concrete of the present invention, which uses cement,
Cementitious material eliminates " lime " in short supply, " gypsum " calcareous material, and lime, gypsum can generate largely in process of production
Dust, the processing technology of air entrained concrete of the present invention reduces environmental pollution, saves cost.
Added with external additive in a kind of physical blowing porcelain powder air entrained concrete of the present invention, the addition of external additive is played
The effect of catalysis, accelerates the coagulation of cement Yu remaining aggregate, and then enhances the intensity of product, and when can be shortened maintenance
Between, save cost;In addition, maintenance method of the present invention is steam curing, relative to traditional steam press maintenance (steam pressure
The temperature of maintenance is 190 DEG C, pressure 1.3MPa, and the time for needing to conserve is 10h), this maintenance method is greatly saved naturally
