Description
Technical field
The present invention relates to a kind of cement composition, foamed cement slurry, foam concrete to pour material and preparation method thereof, belongs to
In foam concrete technical field.
Background technique
Concrete is man-made structures' structural material that current application is most, use scope is most wide.Foam concrete is as mixed
A special kinds in solidifying soil have many advantages, such as that lightweight, heat preservation, heat-insulated, sound insulation, non-ignitable, antidetonation, benefit are useless, can expire well
The requirement of sufficient building energy conservation and building safety, thus foam concrete using more and more extensive.Foam concrete in the preparation,
Foam first is made in foaming agent generally by the method for mechanical system bubble, then foam is added in cement slurry again, forms foam
Slurry, building block or after pouring through conserving.And when using portland cement production foam concrete, due in foam slurry
It will appear lather collapse during the reasons such as the closure and poor toughness of bubble, air bubble liquid-membrane thickness is thin, building block or cast-in-place
And leads to newly to pour building body and collapse mould.For this problem, logical using fast hard rapid hardening special cement substitution portland cement in the prior art
Crossing shortening cementitious material condensation firm time prevents the mould that collapses, and this method setting rate is fast, admittedly bubble effect is good, but fast hard rapid hardening is special
Kind its distribution of cement is not wide, and at high cost, intensity is lower than ordinary portland cement.Another kind prevent from the collapsing method of mould is in foaming agent
Middle a large amount of carboxycellulose, gelatin etc. of adding viscosifies substance by improving foam viscosity to prevent the mould that collapses, and this method makes foam
Stability be improved, but since system viscosity improves, the foaming capacity of foaming agent is reduced with the addition of thickening substance.
Summary of the invention
It can prevent from foam concrete from pouring material the object of the present invention is to provide one kind to collapse the cement composition of mould, have
Advantage at low cost and good foam performance.
The present invention also provides a kind of foamed cement slurries using above-mentioned cement composition, can equally prevent foam coagulation
Soil pours material and collapses mould, and has the advantages that at low cost, foam performance is good.
The foam concrete collapsed the present invention also provides a kind of light and nothing pours material.
The present invention also provides the preparation methods that a kind of above-mentioned foam concrete of simple process pours material.
In order to achieve the goal above, technical solution used by cement composition of the invention is:
A kind of cement composition, the component including following parts by weight: 100 parts of portland cement, 0.5~3 part of foaming agent,
0.2~2 part of thixotropic agent, 0.5~2 part of tackifier, 3~5 parts of early strength agent.
Cement composition of the invention, composition is simple, at low cost, passes through addition thixotropic agent, tackifier and early strength agent and changes
Thixotropy, viscosity and the setting time of foam concrete improve the stability that foam concrete pours material, so that stirring system
Slurry process not only improves foaming agent foam, and can guarantee the stability that blistering is not easily broken, thus avoiding using silicate cement
The foam concrete of mud, which pours material and leads to the problem of, collapses mould simultaneously, guarantees that foam concrete has lower dry density.Using
When the cement slurry of cement composition of the invention is stirred, the bonding forces such as hydrogen bond, electrostatic attraction between thixotropy endowing agent are broken
Bad, thixotropic agent loses network structure, and the viscosity of concrete mortar is lower at this time, is conducive to foaming agent foam, will not make foaming agent
Foaming capacity is impaired.After stirring, thixotropy endowing agent re-forms network knot under the effect of the bonding forces such as hydrogen bond, electrostatic attraction
Structure, concrete mortar show higher viscosity, and the bubble in slurry can be stabilized, and are beneficial to prevent casting matrix and collapse mould；
Tackifier can make air bubble liquid-membrane adsorption value become larger, and surface tension becomes smaller, and Film strength increases, and drain age velocity becomes in foam
Slowly, gas-premeable declines, and foam stability enhancing is beneficial to prevent casting matrix and collapses mould；Early strength agent is adjustable concrete coagulation
And setting rate, shorten curing time, collapses mould to be beneficial to prevent and pour building body.Thixotropic agent benefit in cement composition of the invention
Foaming agent foam in concrete mortar is simultaneously stabilized bubble, and tackifier can make air bubble liquid-membrane intensity increase prevent gas
Bubble rupture, early strength agent can be shortened the concrete curing time, and three's synergistic effect is collapsed mould to prevent foam concrete from pouring building body.
Preferably, the tackifier are selected from one of hydroxyethyl cellulose, hydroxypropyl methyl cellulose, gelatin or any
Combination.
Preferably, the thixotropic agent is selected from organobentonite, montmorillonite, fumed silica, rilanit special, stearic acid
One of zinc, polyethylene wax or any combination.
Preferably, the early strength agent is lithiumation object early strength agent.Lithiumation object early strength agent can make the induction period of hydrated cementitious disappear
It loses, so that portland cement is directly entered aquation accelerated period after adding the water, further increase the stabilization that foam concrete pours material
Property.The lithiumation object early strength agent is selected from one or both of lithium carbonate, lithium chloride.
Preferably, the foaming agent is physical blowing agent.It, can be into one using physical blowing agent compared to chemical foaming agent
Step improves the stability of bubble.The physical blowing agent is selected from dodecyl benzene sulfonic acid, ethoxylated alkyl sulfate, α-alkenyl
One of sodium sulfonate or any combination.
