Description

Cellular concrete and preparation method thereof
Technical field
The invention belongs to a kind of material of construction, refer in particular to our light weight cellular concrete.
Background technology
Traditional masonry residential poor seismic behavior especially burrows at finishing, changes housing construction, improves on the usable floor area, can not satisfy human consumer's requirement.According to China's national situation, the general requirement of body of wall development be by clay matter to non-clay matter, by solid wall to hollow wall, by the fritter body of wall to the bulk body of wall, by the heavy walling to the transition of heat-insulating light walling.And material of construction such as present brick or concrete can not satisfy the needs of lightweight in the building, energy-saving and environmental protection.
Summary of the invention
The invention provides a kind of cellular concrete, to solve the problem that material of construction such as present brick or concrete can not satisfy lightweight in the building, energy-saving and environmental protection needs.The technical scheme that the present invention takes is: comprise masterbatch and the auxiliary material of pressing column weight amount portion rate:
A. masterbatch:
Quick hardening sulphoaluminate cement or Ultrastrength cement: 30~70 parts;
Stopping composition: 25~60 parts;
Ordinary Portland cement: 5~10 parts;
B. auxiliary material:
Water-resisting agent: 1~1.5 part;
Bleeding agent: 2.0~3.0 parts;
Suspension agent: 2.0~5.0 parts;
Suds-stabilizing agent: 0.1~0.5 part;
Honeycomb agent: 38~60 parts.
Auxiliary material also comprises rust inhibitor among the present invention: 0.5~1.5 part.
Auxiliary material also comprises toughener among the present invention: 5~10 parts.
Stopping composition described in the present invention is a kind of in ground granulated blast furnace slag, coal drystone powder, the volcano rock dust.
Water-resisting agent described in the present invention is that a kind of 1: 1 by ratio of weight and the number of copies~3 in a kind of and FDN water reducer, UNF water reducer, NF water reducer and the NNO diffusant in calcium stearate, aluminum stearate, Zinic stearas, Magnesium Stearate and the organic silicon emulsion formed.
The agent of bleeding described in the present invention is a talcum powder.
Suspension agent described in the present invention is light calcium carbonate or unslaked lime.
Rust inhibitor described in the present invention is a Sodium Nitrite.
Suds-stabilizing agent described in the present invention is a kind of in oleic acid, polymethylene amidpulver, polyvinyl lactam powder and the polyacrylamide powder.
The agent of honeycomb described in the present invention is that the following raw materials by weight portion ratio is formed:
0.06~0.09 part in hydrogen peroxide;
1 part of tap water;
In triethanol ammonium, Quilonum Retard, lithium chloride, boric acid, citric acid, tartrate, calcium lignin sulphonate, sodium lignosulfonate and the magnesium lignosulfonate a kind of 0.001~0.003 part.
Toughener described in the present invention is ultra-fine wollastonite powder or ultrafine quartz powder.
The preparation method of cellular concrete described in the present invention, may further comprise the steps: raw material is stirred with 300~800 rev/mins in agitator by prescription, churning time 1.5 minutes~2 minutes, again in the casting mold, finish to going into 2~3 minutes mould time in situ temperature 22~26 degree shapings from stirring.
The present invention is as gelling material with quick hardening sulphoaluminate cement, Ultrastrength cement, the agent of adding honeycomb, suds-stabilizing agent, water-resisting agent, bleeding agent, suspension agent, rust inhibitor, toughener, acid and alkali-resistance fiber, coal drystone powder, slag powders stir jointly, pour into mould and can form cellular concrete.Advantage: not corrosion of reinforcing bar; Early stage bending and compressive strength height, not retraction of later strength; Do not chap; Making processes is easy, and according to the requirement of building structure, its technical indicator can realize by adjusting to cooperate recently.Can make various products at normal temperatures.Be widely used in being incubated, heat insulation, in the construction work of waterproof.Its thermal conductivity changes between caning be controlled in 0.03~0.07; Ultimate compression strength can change between 1.2~4.2MPa, and volume density can be controlled in 200~420kg/m 3Between; The diameter that forms the honeycomb foam is the disconnected mutually lockedin air space group of 2mm-8mm, reaches higher heat-insulating property; Because add water-resisting agent, the cellular cellular body that forms is case type, water not porous wherein reaches the hydrophobic effect; After 25 thawings of freezing and thawing test, mass loss is less than 4.5%, and main raw is made up of inorganic materials, therefore has uninflammability; Owing to use quick hardening sulphoaluminate cement as gelling material, after 4-6 hour intensity of cast reached the 60-70% of design label, the next process construction was convenient in the self-support moulding that begins to harden usually; Metal is not corroded.
Advantage of the present invention and beneficial effect are:
1, lightweight, high-strength, long service life, high-efficiency insulated, heat insulation, sound insulation, from waterproof, do not fire, characteristics such as shock resistance, shrinking percentage are little, and thoroughly solved the problem that severe cold area buildings in winter produces " cold bridge ".Its thermal resistance is equivalent to 8.5 times of burned brick, burn 120 minutes with 900 ℃ of high-temperature bakings of blowtorch after, not lost integrity and heat insulating ability, and 44 ℃ of back side medial temperatures, 68 ℃ of the temperature of vertex have splendid fire-resistant and heat-proof quality.
2, construction install convenience can plane, saw, nail etc., can with the supporting use of any structure system, can use modes such as welding, bolt and weldering to be connected with structural system according to design requirements, saved construction period to greatest extent.
3, reduce the weight of buildings, volume of the same area, the weight of product material of the present invention only is 1/8th of brick wall, alleviates load significantly, has reduced the bearing capacity of concrete foundation and steel frame, has reduced the consumption of other material.
4, increase usable floor area, body of wall of the same area reduces thickness, and every cover room increases usable floor area 8-10%.
5, this product is used for large-scale roofing, building flat roof deck, pitched roof, has characteristics such as insulation, rigid self-waterproof, load-bearing, and splicing seams is done flexible water and handled, and will cancel vapour barrier, thermal insulation layer, the constructional method that flexible waterproof layer etc. are traditional.
6, can be ornamental strong, can represent the design style of building to greatest extent.Building coating, decoration ceramic tile, Dali stone material and various metal lagging all can be used with product of the present invention.
7, production and construct very convenient, promptly can produce in factory, again can field fabrication.
8, the Ultrastrength cement and the quick hardening sulphoaluminate cement that adopt of this product belongs to low alkalinity cement, and the product material weather resistance of made can reach 80-100, and when 200 ℃ of high temperature, 72 hours indeformable, aging.And the color steel mesh frame roofing thermal-insulating board that present construction market generally adopts, two-sided color steel, interior sandwich styrofoam, back (temperature is at 70 ℃) styrofoam distortion of being heated, color steel promptly fades at solar irradiation, wind, the 7-10 that drenches with rain, and has increased the maintenance cost in house.Simultaneously, its erosion resistance is poor, and MaLS is no more than 20-30, and though with lightweight, high-strength this product roof boarding on the price and all incomparable on working life.
The physicals of product of the present invention:
1, volume density is at 200-420kg/m 3
2, ultimate compression strength is at 1.2-4.2Mpa
3, folding strength 〉=0.8Mpa
