Abstract
The invention discloses a foam concrete, whose slurry is composed of silicon material, calcium material, water and composite foaming agent, the composite foaming liquid is composed of 5-15% of foam-solidifying agent fatty acid methanol amide in mass percentage and 90-95% of rosin foaming agent in mass percentage. The composite foaming liquid in the foam concrete provided by the invention contains:5-10% by mass of foam-solidifying agent based on the mass of the foaming agent and 90-95% by mass of rosin foaming agent based on the mass of the foaming agent. The existence of the foaming agent isgood for preventing formed bubbles from expansion and rupture, which effectively eliminates the phenomenon that bubbles have different sizes, thereby formed pores are uniform and dense, after mixed stirring, casting moulding and maintenance of slip, quality is lighter and intensity is higher, thermal insulation performance is good.
Description
Technical field
The present invention relates to a kind of light building material, relate in particular to a kind of foamed concrete.
Background technology
At present, the foamed concrete with lightweight, insulation, heat insulation, sound insulation, fire-resistant function has obtained widespread use in building operation.
Foamed concrete normally is prepared into foam with mechanical means with foaming agent water solution, again foam is joined and contain in the slip that siliceous material, calcareous material (cement, lime), water and various admixture (how adopt usually based water reducer, hardening accelerator) etc. form, through mixing a kind of porous material that stirring, casting, maintenance form.Owing to contain the tiny hole of a large amount of sealings in the foamed concrete, therefore have good thermal and insulating performance, density rating is at 300～1200kg/m usually
3, the foamed concrete of scope, thermal conductivity is between 0.068W/ (mk).
The production method of foamed concrete has two kinds of wet mortar method and dry mortar methods.The wet mortar method normally stirs into mortar at concrete mixing plant with cement, sand etc., and be transported to the building site with the truck mixer car, the foam that to make separately again adds mortar, stirrer is mixed foam and mortar thoroughly, then the foamed concrete for preparing is injected pump truck conveying or on-the-spot directly construction.The dry mortar method is each dry basis (cement, flyash etc.) will be transported by loosing or transmission system is delivered to the working-yard, dry basis and water is mix at the construction field (site), the foam that to make separately then adds mortar, and both are mix in homogenizer, is used for site operation then.
Because this foamed concrete denseness is less, its viscosity can not overcome foamy surface spreading power, the foam of different positions in the slip, increase in various degree appears in its diameter in time, thereby make its part foam diameter bigger than normal, and foam diameter is not of uniform size, adds the bubble shakiness, becomes bubble rate ability drop; Finally influence into the quality of bubble.
Summary of the invention
The invention provides foamed concrete that a kind of quality is lighter, intensity is bigger, hole quality is high and preparation method thereof.
A kind of foamed concrete, its slurry is made up of siliceous material, calcareous material, water and composite foamable agent, and described composite foamed liquid is that 5%～10% solid infusion fatty acid methyl alcohol amide and mass percent are that 90%～95% rosin whipping agent is formed by mass percent.
Described is sand or flyash by siliceous material, and described calcareous material is a cement, and the mass ratio between described each composition is: siliceous material: cement: water=3: 2: 3.
Described is sand and flyash by siliceous material, and described calcareous material is a cement, and the mass ratio between described each composition is: sand: flyash: cement: water=1: 2: 2: 3.
Owing to contain solid infusion that accounts for whipping agent quality 5%～10% and the rosin whipping agent that accounts for whipping agent quality 90%～95% in the composite foamable agent in the foamed concrete of the present invention, the existence of described solid infusion is beneficial to the bubble that has formed and no longer continues to expand so that break, eliminate bubble phenomenon not of uniform size effectively, the pore that forms after forming with slip mixing stirring, casting, maintenance is evenly closely knit, quality is lighter and intensity is high, and heat-insulating property might as well.
Embodiment
A kind of foamed concrete, its slurry is made up of siliceous material, calcareous material, water and composite foamable agent, and described composite foamed liquid is that 5%～10% solid infusion fatty acid methyl alcohol amide and mass percent are that 90%～95% rosin whipping agent is formed by mass percent.Described fatty acid methyl alcohol amide general structure is: RCNHCH
2OH.Described rosin whipping agent is a whipping agent common on the market.
First kind of embodiment: a kind of foamed concrete, its slurry is made up of siliceous material, calcareous material, water and composite foamable agent, and described composite foamed liquid is that 6% solid infusion fatty acid methyl alcohol amide and mass percent are that 94% rosin whipping agent is formed by mass percent.
Second kind of embodiment: a kind of foamed concrete, its slurry is made up of siliceous material, calcareous material, water and composite foamable agent, and described composite foamed liquid is that 9% solid infusion fatty acid methyl alcohol amide and mass percent are that 91% rosin whipping agent is formed by mass percent.
The third embodiment: a kind of foamed concrete, its slurry is made up of siliceous material, calcareous material, water and composite foamable agent, and described composite foamed liquid is that 7.5% solid infusion and mass percent are that 92.5% rosin whipping agent is formed by mass percent.
Described is sand or flyash by siliceous material, and described calcareous material is a cement, and the mass ratio between described each composition is: siliceous material: cement: water=3: 2: 3.
Described is sand and flyash by siliceous material, and described calcareous material is a cement, and the mass ratio between described each composition is: sand: flyash: cement: water=1: 2: 2: 3.
Foamed concrete with present embodiment 1 to 3, do apparent density, 28d ultimate compression strength and thermal conductivity by the method for " lightweight aggregate concrete technology rules " JGJ51-2002 and " building mortar basic performance tests method " JGJ70-90 and detect, its detected result is as follows:
| Embodiment | ??1 | ??2 | ??3 |
| Do apparent density kg/m 3 | ??442 | ??465 | ??450 |
| 28d ultimate compression strength | ??1.4 | ??3.1 | ??2.3 |
| Thermal conductivity W/ (mk) | ??0.056 | ??0.084 | ??0.073 |
From above-mentioned detected result as can be known, 450kg/m
3The thermal conductivity of foamed concrete only be 0.073W/ (mk), less than the required value 0.1W/ (mk) of national standard to the thermal conductivity of B03 level building block, but ultimate compression strength is but much larger than the requirement of strength value 1.0Mpa of national standard to the building block of B03 level, can be under the situation that reduces thickness of wall body greatly, just can reach the requirement of country energy-conservation 65%, also can under the constant situation of floor area of building, increase the interior space.
