Description
Technical field
The present invention relates to building material technical field, in particular it relates to a kind of body of wall filling foam concrete and system thereof
Preparation Method.
Background technology
Cement based foam concrete is uniformly to be introduced in cement mortar by bubble, formed through molding and maintenance containing a large amount of gas
The lightweight concrete in hole.Owing to it has the advantage such as light weight, good, the A level not combustion of thermal and insulating performance, it is widely used in
The fields such as building heat preservation, wall barrier, Foundation treatment, bank protection process.Due to each field to the performance requirement of foam concrete not
With, actual production can be controlled the density of foam concrete by the addition changing bubble, and by adding different merits
Component can realize property.
Foam concrete is applied to materials for wall and is usually present some problems, and the foam as used normal silicate to prepare mixes
Solidifying soil is longer for setting time, the phenomenon such as mould, sinking of collapsing easily occurs；And use foam concrete prepared by sulphate aluminium cement by
Short setting time, aquation is fast, the problems such as the easy efflorescence in surface easily occurs.
Summary of the invention
The deficiency existed for prior art, the invention provides one and is difficult to collapse mould and sinking and surface is not pulverized easily
Body of wall filling foam concrete and preparation method thereof.
For solving above-mentioned technical problem, the present invention adopts the following technical scheme that
One, body of wall filling foam concrete, its raw material includes Binder Materials, mixing water, foaming agent, hydrophober, surely steeps
Agent, coagulant and water reducer；Wherein:
Binder Materials is the mixture of portland cement and aluminate cement, and aluminate cement quality is silicate cement shale
The 10%～20% of amount；Mixing water, foaming agent, hydrophober, foam stabilizer, coagulant, the quality of water reducer are respectively Binder Materials
The 38% of quality～45%, 0.5%～1%, 1.5%, 0.05%～0.2%, 1%～3%, 0.6%～0.8%.
Further, foaming agent is animal protein foaming agent.
Further, hydrophober is calcium stearate.
Further, foam stabilizer is methyl hydroxyethylcellulose ether.
Further, coagulant is sodium aluminate.
Further, water reducer is polycarboxylate water-reducer, white sugar and the mixture of 1-hydroxy ethylidene-1,1-diphosphonic acid (HEDP), its
In, the mass ratio of polycarboxylate water-reducer, white sugar and 1-hydroxy ethylidene-1,1-diphosphonic acid is 1:(0.1～0.2): (0.1～0.3), and diminishing
The solid content of agent is 12%～15%.
Two, the preparation method of above-mentioned body of wall filling foam concrete, including:
Foam after foaming agent and water are mixed, it is thus achieved that foam；
Epoxy glue gel material, hydrophober, foam stabilizer and coagulant obtain mixture, add water reducer and mix in mixture
Heshui, agitated acquisition slurry；
Mix-froth and slurry obtain foam concrete.
Further, in foaming after foaming agent and water being mixed, the mass ratio of foaming agent and water is 1:30.
In the present invention, Binder Materials is mixed in proportion by portland cement and aluminate cement and forms, and it reacts raw with water
Become there is the Behavior of Hardened Cement Paste of some strength, provide skeleton for foam concrete.Retarder in coagulant and water reducer is as condensation
Time adjusts component, can prevent slurry from occurring collapsing according to the setting time of ambient temperature adjustment foam concrete to suitable interval
The phenomenon such as mould and sinking.Water reducer is mainly used to reduce the water-cement ratio of foam concrete, while reducing the generation of bleeding passage,
Improve foam concrete intensity.Foaming agent is under mechanical external force effect, and formation hydrophobic group is outside, inside the stablizing of hydrophilic group
Foam.Foam stabilizer can increase slurry viscosity, the most also can strengthen foamy body, improves foam stability in slurry, enters one
Step reduces by lather collapse, excessive and collapse mould and the sinking of foam concrete that cause.Hydrophober not only can significantly reduce foam
The water absorption rate of concrete, moreover it is possible to the stability of strengthening foam, plays steady bubble effect.
Compared to the prior art, the invention have the advantages that and beneficial effect:
Foam concrete of the present invention has that lightweight, high intensity, setting time be short, low water absorption, lower shrinkage, the mould that is difficult to collapse,
Be difficult to, the feature that is not pulverized easily of surface.The dry density of gained foam concrete is 300～500kg/m3, intensity be 0.4～
1.5MPa, setting time is 2～5 hours, and within 24 hours, water absorption rate is less than 10%；Pour after molding after 7 days, any depression does not occurs
Phenomenon, through form removal sampling discovery body of wall upper and lower unit weight deviation less than 5%, fire-protection rating is A level, is the good of filling materials for wall body
Select.
