(2) foam concrete production operation main points
The manufacturing process of foam concrete comprises base cleaning, has propped up template and has watered moisteningly by designing requirement, the preparation of foam preparation, foam concrete compound, builds moulding, maintenance and check.
1, foam preparation
Foam preparation adopts special foam maker, through air compressor foaming agent is imported the automatic bubble systems produce and becomes foam.
2, compound preparation
Cement of working good and water etc. are stirred with foaming machine, mix in pipeline with foaming agent then and be delivered to construction part and build moulding by high-pressure pump.Thick fluid pump pressurization pressure scope is in the cast of energy-saving solar greenhouse body of wall: 12MPa-14MPa.
3, build moulding
The temperature of job site must not be lower than 5 ℃, should be clean before building basic unit's foreign material cleaning cleaning, and water is moistening; Foam concrete is the fluid of thickness, wherein contains a large amount of air and adsorbed water; Discharge nozzle must not swing back and forth in foam concrete and timely surperficial levelling to foam concrete; Foam concrete begins to build after the mix bubble is more stable, detects quantity of sampling quantity and carries out field sampling with air-entrained concrete building block standard-required (three), treats that foam concrete solidifies ability stripping after 72 hours in order to avoid destroy finished product.Will carry out placement layer by layer if the foam concrete height of building surpasses 100cm, guarantee that the crack does not appear in the finished product or the semiproduct of building, guarantee the planeness on cast-in-place foamed concrete surface.
4, maintenance
The mode of felt or woven straw covering and watering maintenance is taked in natural curing.
5, check and finished product protection
Should send the special messenger to be responsible for supervision after foam concrete is built and finished, built do not allow in 48 hours to stack material and on people construction, carry out product inspection and protection work.
6, the foam concrete construction cooperates points for attention when
The foam concrete compound will stir, and the mix consumption of strict control foaming agent guarantees the accuracy of foam concrete match ratio; The consumption of necessary strict control water when stirring the foam concrete compound; Because foaming agent is an alkaline matter, so construction water must adopt the water of nonacid material to mix in the foaming agent in order to avoid produce the foam effect that chemical reaction influences foaming agent, the Acidity of Aikalinity of available ph test paper test construction water.
7, quality control
The quality requirements of raw materials of cast-in-place foamed concrete adheres to specification; The match ratio of cast-in-place structural foam concrete is controlled in strict accordance with the density of material grade of designing requirement, guarantees that the technical performance index of foam concrete reaches designing requirement; Foam concrete is built the back will carry out levelling in order to avoid destroy the quality of in type foam concrete to its surface in half an hour; Built behind the foam concrete the detection of taking a sample of the technical indicator of its quality.
(3) foam concrete detection method
In the middle of the use of foam concrete, there is much human not note its detection method; Thereby caused in the use and various mistakes occurred; The applicant in use passes through test of many times and contrast; Summed up following detection method, can be everybody conduct in actual use from now on and use for reference, guaranteed that everybody uses foam concrete quickly and accurately.
1, use before with the foam sedimentation apart from the measurement foam stability.After foam takes place, with following method measurement foam sedimentation distance: getting internal diameter is 6cm, the container of high 9cm (or volume is about the container of 250 mls with size is close); Fill with de novo foam; Scrape plane surface, multiple paper is one on foam, is placed on calm place imperturbably and measures the sedimentation distance after 40 minutes.Technical indicator: coefficient of foaming is 20 times, and sedimentation is apart from being not more than 1cm.
2, the assay method of coefficient of foaming is that the foam of processing is filled with volume is that 250 ml, diameter are in the glass tank of the no end of 6cm, and wipe off at two ends, claims its weight.Design formulas is: M=VY/ (G
2-G
1), wherein: the M-coefficient of foaming; V-glass tank volume (ml); Y-foaming agent solution density (is bordering on 1g/ml); G
1-glass tank quality (g); G
2-glass tank and foam quality (g).
3, when detecting foam concrete when test block float on do not produce in the water dissolve, fall heavy, thereby explain this foam concrete solidify fully with pore be Totally-enclosed-type.Case type foam concrete air can not produce convection current in vivo, thereby has reduced radiation, conduction, the diffusion of temperature yet, thereby heat energy is weakened at pore gradually, to reach adiabatic effect.And water absorption rate is low, and greatly about about 5%, and the physical property of sound insulation, resistance to compression, waterproof, anti-folding etc. is best.
If 4 when detecting test block slowly sink; Water absorption rate reaches 30%, thereby explanation foam concrete pore is semi-open type, if partly pore is to be connected from showing the lining; Air will produce convection current in vivo; Therefore the heat insulation time can increase along with the degree of opening of pore and shorten, thereby the water rate of attracting deposit also can increase to about 50% along with the connection rate of pore, protects dim, resistance to compression, sound insulation, heat insulation, waterproof, the anti-physical property of rolling over will significantly reduce.
If 5, the very fast submerged of test block in detection.Just explain that water absorption rate surpasses 30%; Therefore the pore in this material is that standard-sized sheet is put; Thereby form from showing the passage of lining, air produces convection current in passage, so air carries out radiation, conduction, diffusion through moisture content with the temperature of material in convection current; The water rate of attracting deposit also can increase to more than 50% with pore connection rate gradually, so this material loses the performance requirement of heat-insulation warm keeping.
Four. Analysis of application result
The performance of foam concrete does not receive the influence of height above sea level basically, and suggestion selects 425 at high and cold, energy-saving solar greenhouse, high altitude localities body of wall for use in building
#Cement is made raw material, selects ZF-100 type cementitious composite foaming agent for use, and the foaming agent extension rate is 20 times, and environment temperature should be selected water/binder ratio 0.4 for use more than 5 ℃ during pouring construction, and wet density is 500 kg/m
3Foam concrete build; It is 20cm that body of wall is built width, should carry out laminated pouring when pouring into a mould height greater than 100cm.
