Abstract
The present invention discloses a foam concrete light wall-body material and the corresponding preparation method; the detailed preparation method is that: the components in the present invention such as water, common cement and medium sand (powder coal ash or industrial cinder) are added into a milling pot to be milled evenly and enough according to weight ratio with 0.8 : 1: 1 of water: common cement: medium sand; and the components in the foam agent includes rosin, sodium hydroxide and glue agent; according to the weight ratio with 15 : 1: 18 of rosin : sodium hydroxide : glue agent, the rosin, sodium hydroxide and glue agent are added into a container to be milled evenly and enough to obtain the foam agent. And then the foam agent and the water with the weight ratio of 1: 50 are respectively added into a foam pot; the pressure is increased to 8kg to the foam pot by a common air pump; the foam agent in the pressure situation is ejected into the milling pot of the concrete by a foam gun and then to be milled evenly and enough. The foam concrete can be obtained after the foaming process is stable, and then the foam concrete is ejected into a mould; the mould can not be dismantled until the natural conservation reaches the intension requirement of the dismantlement. Finally, after being maintained in 25 DEG C for 8 hours, the foam concrete light wall-body material with the density of 700- 900kg/m<SUP>3</SUP> can be obtained.
Description
Technical field
The present invention relates to a kind of preparation method of foaming concrete lightweight wall material, belong to the manufacturing technology of material of construction.
Background technology
Chinese patent application numbers 200510047439.0 discloses a kind of " making method of foaming concrete lightweight wall material in situ ", it is earlier hydrogen peroxide and the water of quality 5-10% to be mixed, with the aluminium powder of cement quality 2-7% and cement, sand, stone uniform mixing; Then above-mentioned two kinds of mixtures are mixed, stir to be filled into and put up in the template; The i.e. foaming and form intensity in template of 4 hours (20 ℃) back concrete, treat that intensity reaches the form removal requirement after, form removal, it is final after maintenance that to form density be 1800-2100kg/m
3Body of wall.The foamed concrete that this method is manufactured, its density are still very big, and the sound-insulating effect is still not good enough, and the labour intensity during use is still bigger.
Summary of the invention
The present invention aims to provide a kind of light wall material, and the sound-insulating performance is good, foamed concrete that fire-resistant antidetonation, thermal conductivity and water-intake rate are low and preparation method thereof.
For achieving the above object, the preparation method of foaming concrete lightweight wall material of the present invention is: concrete is a water by the composition weight ratio: Portland cement: medium sand (or flyash, or industrial cinder all can) equal 0.8: 1: 1 ratio, place stirred pot to stir water, Portland cement and medium sand respectively; The composition of whipping agent divides by weight being rosin: sodium hydroxide: the ratio that ox glue equals 15: 1: 18, respectively rosin, sodium hydroxide and ox glue are placed mixing and stirring in the container, and make whipping agent; It in whipping agent and water 1: 50 ratio, respectively whipping agent and water are injected in the foamed pot, be forced into 8kg with common air pump to foamed pot, whipping agent under the high pressure is injected concrete drums with foam gun to stir, make the stable back of its foaming form foamed concrete, foamed concrete is injected mould, treat that its natural curing is collapsible die after reaching the form removal desired strength, promptly forming density again after 8 hours (25 ℃) maintenance is 700-900kg/m
3Foaming concrete lightweight wall material.
The preparation method of foaming concrete lightweight wall material of the present invention compared with prior art has following excellent effect.
1) in light weight.Adopting the density of the foaming concrete wall material of the inventive method preparation is 760kg/m
3, be about 1/3 of clay, be about 1/2 of hollow concrete block.
2) resistivity against fire is good.Adopt the foaming concrete wall material of the inventive method preparation can not burn, its thermal conductivity is 0.21m/m.k, reaches country-level fire protection requirement.
3) water-absorbent is poor.Adopt the ball-like structure of internal porosity for sealing of the foaming concrete wall material of the inventive method preparation, still floating after 24 hours in the immersion water, water-intake rate is less than 15%.
4) insulation, thermal insulation is good.Adopting the thermal conductivity of the foaming concrete wall material of the inventive method preparation is 0.21m/m.k, and its heat preservation effect is 4 trainings of unselected clay, is that amass wealth by heavy taxation 3 of hollow concrete block, can fall room temperature 5-6 ℃ at roof of storied building as thermofin.
5) sound-absorbing, sound insulation are good.Because the foaming concrete wall material of the inventive method preparation has vesicular structure, sound-absorbing, sound-proofing properties are relatively good.
6) free from environmental pollution, the starting material that the present invention adopts are environment-friendly materials, environmentally safe.
7) shock resistance is good.Density of material of the present invention is little, greatly reduces the deadweight of buildings, can improve two antidetonation ranks.
Material of the present invention extensively is suitable for buildings and uses.
Embodiment
At first, by weight being water: ortho-water mixes: the ratio that medium sand equals 0.8: 1: 1 places stirred pot to stir in Portland cement, medium sand and water respectively; Secondly, by weight being rosin: sodium hydroxide: the ratio that ox glue equals 15: 1: 18, respectively with rosin, sodium hydroxide and ox glue place mixing and stirring in the container, make the foaming system, be 1: 50 ratio again in foaming system and water, respectively whipping agent and water are injected in the foamed pot, in foamed pot, be forced into 8kg with common air pump, whipping agent under the high pressure is injected concrete drums with foam gun to stir, after making its foaming stable, form foamed concrete, foamed concrete is injected mould, treat that its natural curing is collapsible die after reaching the form removal desired strength, promptly forming density again after 8 hours (25 ℃) maintenance is 700-900kg/m
