Description
Technical field
The invention belongs to building charging technical field, particularly relate to a kind of High-performance cast-in-place foam concrete.
Background technology
Cast-in-place foamed concrete refers to physical method foaming agent water solution be prepared as foam, then foam is joined by
Cement, gather materials, in slurry that admixture, additive and water etc. are made, lightweight cellular concrete.There is heat insulating ability, light
Matter, globality, low bullet damping property, sound-proofing, crushing resistance, resistance to water, durability, the feature of environmental protection and economy.Due to cast-in-place bubble
Foam concrete has high-strength light, can improve the advantage of project progress and construction quality, has replaced in terms of building and road and bridge
For traditional construction way and material, detailed applications is as follows: as retaining wall；Build sports ground and track and field runway；Lean coagulation
Soil packing course；Roofing side slope；The support of storage tank footing；The application of the technical fields such as cast-in-situ wall.
High performance cast-in-place product and high performance cellular concrete product are few, the defect existed: in secondary stirring
During, dry density is the lowest, and foam is more difficult to uniformly, to cause foam aperture size and skewness, intensity with the mixing of slurry
Low, heat conductivility declines；During secondary stirring, along with the loss of foam, slurry can be increasingly diluted, thus causes gathering materials
Sedimentation, it is impossible to be evenly distributed in slurry, make construction and intensity be difficult to be guaranteed；Intensity and heat conductivity conflict, if thinking
Reduce heat conductivity, it is necessary to improve the content of foam, the i.e. porosity in foam concrete, thus cause the reduction of intensity；Bubble
In foam concrete, air vent wall structural constituent is unreasonable, is formed and non-fully closes hole, causes water absorption rate to increase, under heat conductivility
Fall；Portland cement is long for setting time, and foam defoaming process is fast, the generation of the mould phenomenon that causes collapsing；Sulphate aluminium cement
Mix, along with external environment changes, through certain time, efflorescence can occur.
Flyash contains the vitreous body of more than 70%,.Gelation activity is will become apparent under highly basic excitation.Mix at foam
In solidifying soil, highly basic constantly released by cement because of aquation, produces chemical reaction with flyash, generates the aquation silicic acid with gelling property
Calcium, low sulfur type and high sulfur type hydrated calcium aluminate sulfate, promote foam concrete gain in strength.
Summary of the invention
It is an object of the invention to provide a kind of High-performance cast-in-place foam concrete, by using wood fibre, graphite powder
With flyash, this foam concrete is modified；Improve foam concrete intensity by flyash, and cost can be reduced, fall
Low-shrinkage, improves crack resistance.
For solving above-mentioned technical problem, the present invention is achieved by the following technical solutions:
The present invention is a kind of High-performance cast-in-place foam concrete, including counting by weight, the cement of 100-520,25-
The admixture of 180, the light-weight aggregate of 80-320, the foaming agent of 0.8-6.4, the water of 75-300, the flyash of 50-100,1.6-12
The modifying agent mixing of additive and 2-28；
Described cement is Portland cement；Described admixture is breeze；Described additive is polycarboxylate water-reducer, silicon
Acid calcium and sodium sulfate；Described modifying agent is wood fibre, graphite powder, hydrophober, and described light-weight aggregate is the shale of particle diameter 3-12mm
Haydite；
Described breeze mixes with the flyash ratio of 1-2:1 by weight；Described polycarboxylate water-reducer, calcium silicates and sulphuric acid
The sodium ratio of 1:2:2 by weight mixes；Wood fibre, graphite powder, the hydrophober ratio of 1:2:1 by weight mixes；
Described wood fibre length is between 11-20mm；Described light-weight aggregate is haydites of book structure, particle diameter 3-12mm, cylinder pressure
Degree more than 4.5Mpa.
The method have the advantages that
This foam concrete is modified by the present invention by using wood fibre, graphite powder and flyash；Pass through fine coal
Ash improves foam concrete intensity, and can reduce cost, reduces shrinkage factor, improves crack resistance；Being strengthened by wood fibre should
The fracture toughness of foam concrete；By graphite powder as the surface lubrication of this foam concrete, it is simple to the demoulding.
Certainly, the arbitrary product implementing the present invention it is not absolutely required to reach all the above advantage simultaneously.
