Abstract
The invention discloses a preparing method of on-site foaming concrete lightweight wall material in the architecture wall material preparing technique domain, which comprises the following steps: mixing the hydroperoxide of 5-10 percent water weight and water evenly; blending the aluminum powder of 2-7 percent cement, cement, sand and stone uniformly; pouring two mixtures in the built mould; foaming the concrete in the mould to form strength after 4 hours at 20 deg.c; demoulding to obtain the wall of 1900kg/m3 density.
Description
Technical field
The present invention relates to a kind of preparation method of foaming concrete lightweight body of wall, particularly relate to a kind of preparation method of foaming concrete lightweight wall material in situ, belong to the technology of preparing of construction material.
Background technology
The basic demand of construction material be have certain intensity and preferably the insulation, defening effect.Construction material generally adopts clinker brick, hollow brick, foaming building blocks or other compound light wall materials at present, for example, the Chinese invention patent application provide for No. 94112087.2 by 1.0-2.5 weight portion particle diameter be not more than foamed plastic (polystyrene) discarded object of 10mm, ceramic powder, 20-40 weight portion flyash and 100 parts by weight of cement that 5-15 weight portion particle diameter is not more than 1mm mix, add an amount of water furnishing pasty state, the mould that injects required specification solidify and " a kind of foaming plastic ceramic coals ash cement light wall material "; The Chinese invention patent application provides " a kind of novel light wall material " that is mixed together by the polystyrene foam grain of 50-70% cement, the treated mistake of 30-50%, 10-20% flyash or ore deposit quarrel ash, 1-3% silicate of soda or paraffin wax emulsions and water for No. 99116095.9; The Chinese invention patent application provides for No. 200410021951.3 by flyash, slag powders, cement, blowing agent, conditioning agent and water, the weight portion of each material outside wherein dewatering is respectively: flyash 30-45, slag powders 10-20, cement 30-45, blowing agent 3-12, conditioning agent 1-2 adds water and fully stirs " the multifunctional inorganic foam materials for wall " that forms.These materials substantially all are prefabricated production, build by laying bricks or stones behind the scene or splice.The on-the-spot labour intensity of this method is bigger, and the porosity of body of wall is little, and insulation and defening effect are poor.Direct cast wall material is also arranged at the scene, stir into concrete, in prefab form, pour into materials for wall again but add water after being mostly to mix by a certain percentage with cement, sand, stone.It is the cast-in-situ wall material of primary raw material preparation with building waste mixture or gangue that the Chinese invention patent application has provided for No. 200310111249.1 a kind of, be with material such as cement, building waste mixture or gangue, sand, coal ash, additives, mix by a certain percentage and stir, cast-in-site, one-shot forming.Though the materials for wall that provides in the technique scheme can on-the-spotly directly be poured into a mould, but the material that adds is too many, floor space is excessive, makes troubles to site operation.
Summary of the invention
The objective of the invention is to overcome the prior art above shortcomings, improve by continuous test, provided a kind of preparation method of foaming concrete lightweight wall material in situ, this method utilizes aluminium powder and hydrogen peroxide to be blowing agent, mix and stir at the scene, construction, can build according to the body of wall shape of on-the-spot needs and touch plate, hydrogen peroxide and water are mixed, with aluminium powder and cement, sand, the stone uniform mixing, then 2 kinds of mixtures are mixed, stirring is filled into to put up and touches in the plate, and concrete can foam in touching plate and form intensity, treat intensity reach tear open touch requirement after, tear open and touch, can form qualified body of wall through maintenance.
The technical scheme that the present invention provides is: the preparation method of this foaming concrete lightweight wall material in situ is characterized in being made of following steps:
(1). earlier hydrogen peroxide and the water with water quality 5～10% mixes, with cement quality 2～7% aluminium powders and cement, sand, stone uniform mixing;
(2). then above-mentioned 2 kinds of mixtures are mixed, stir to be filled into to put up and touch in the plate;
(3) the i.e. foaming and form intensity in touching plate of .4 hour (20 ℃) back concrete, treat intensity reach tear open touch requirement after, tear open and touch, it is final after maintenance that to form density be 1800～2100kg/m
3Body of wall.
Said aluminium powder of the present invention and hydrogen peroxide are meant common technical grade aluminium powder and hydrogen peroxide.
The mixed proportion of the said cement of the present invention, sand, stone is 1: 2: 3 or according to other match ratio of requirement of strength design.
The said maintenance of the present invention is meant natural curing.
The present invention is said to put up and touches plate and be meant common steel, wooden form.
Compared with prior art, the invention has the beneficial effects as follows:
1. construction error simple, that raw material is easy to get, proportioning allows is big, cost is low.
2. final strength of wall body height, light weight, the tolerant noise-insulating warm-keeping that forms is effective.
The specific embodiment
Embodiment 1
The hydrogen peroxide and the water of water quality 7% are mixed, with cement quality 5% aluminium powder and cement, sand, stone uniform mixing, wherein the mixed proportion of cement, sand, stone is 1: 2: 3, then 2 kinds of mixture rapid mixing, stirring are filled into to put up and touch in the plate, 4 hours (20 ℃) back concrete can foam the final density that forms at 1800kg/m in touching plate
3Body of wall.
Embodiment 2
The hydrogen peroxide and the water of water quality 5% are mixed, with cement quality 3.5% aluminium powder and cement, sand, stone uniform mixing, wherein the mixed proportion of cement, sand, stone is 1: 2: 3, then 2 kinds of mixture rapid mixing, stirring are filled into to put up and touch in the plate, 4 hours (20 ℃) back concrete can foam the final density that forms at 1900kg/m in touching plate
3Body of wall.
Embodiment 3
The hydrogen peroxide and the water of water quality 3% are mixed, with cement quality 2% aluminium powder and cement, sand, stone uniform mixing, wherein the mixed proportion of cement, sand, stone is 1: 2: 3, then 2 kinds of mixture rapid mixing, stirring are filled into to put up and touch in the plate, 4 hours (20 ℃) back concrete can foam the final density that forms at 2100kg/m in touching plate
3Body of wall.
