Description
Technical field
Present invention design air entrained concrete field, specifically a kind of method for repairing air entrained concrete sheet material defect.
Background technology
Air entrained concrete sheet material is a kind of new green wall material, and it has fire resistance rating high, and sound-proofing is good, construction
Speed is fast, the excellent feature of thermal and insulating performance, progressively starts to substitute autoclave aerated concrete building block as building packing material.Its
It can also be applied to the exterior wall of building.
Air-entrained concrete building block be by reinforcing bar and slurry by pouring into a mould, resting, cutting, steam-cured four procedure is prepared
's.Because the expansion coefficient difference of the coefficient of expansion and Aerated Concrete base substrate of reinforcing bar is big（0.8 × 10-5m, 1.2 × 10-5m）, cause
For sheet material during steam-cured, internal stress causes micro-crack, and the crackle more than 1mm occurs in surface when serious.These micro-cracks and
The big crackle on surface easily easily causes coming off for concrete base substrate in the handling process.Once sheet material defect, slight will can lack
Damage Partial Resection, remainder sale；Seriously monoblock sheet material will be caused to discard.Contain reinforcing bar in sheet material, production cost is 400
Member/side.Once cutting is discarded, cost allowance is serious.
The content of the invention
The technical problems to be solved by the invention are：How the air entrained concrete sheet material that has defect is repaired.
The technical solution adopted in the present invention is：A kind of method for repairing air entrained concrete sheet material defect, according to following
Step is carried out：
Step 1: the cross sectional area for the air entrained concrete sheet material defect for needing to repair is polished using sand paper, ensure
Smooth surface, no projection；
It is Step 2: the air entrained concrete sheet material repaired of needs by step 1 processing is horizontal positioned, it is necessary to repair
108 glue are uniformly smeared at position, will repair the bottom at the framed position for being placed on and needing to repair；
Step 3: by land plaster mass percent account for 60 ~ 80% land plaster and cement admixture stirring in add water, water
Quality for land plaster and cement admixture gross mass 50-60%, after being well mixed, immediately by material pour into repairing it is framed in
And vibrated, while it is framed to rap repairing, and stomata is discharged, keeps material to be higher by repairing plane 1- where aerated concrete panel
2 centimetres, pour into the framed middle interlude of repairing to material after material is well mixed and be no more than five minutes, vibrating to finish to be higher by adds
The material of repairing plane scrapes off where gas concrete slab；
Step 4: being stripped after being poured rear 7-10 minutes, 108 glue are smeared in patched surface of position, and use scraper
The air entrained concrete fragment that leaves of being polished in step 1 is worn into powder and is uniformly applied to by plate smears the surfaces of 108 glue, makes repairing
The color for the surface of position crossed and not patched surface of position solid colour.
As a kind of preferred embodiment：The framed angle mould frame and two pieces of planks made including three pieces of planks of repairing in step 2
The rib of making is framed, and angle mould frame is used to repair corner defect, and rib is framed to be used to repair seamed edge defect.
The beneficial effects of the invention are as follows：This patent realizes the timely repairing of the apparent defect of air entrained concrete sheet material, improves
The qualification rate of sheet material, reduce the rejection number of sheet material, greatly promote the economic benefit of enterprise.

Fig. 2 is present invention repairing seamed edge defect schematic diagram；
Fig. 3 is angle mould mount structure schematic diagram；
Fig. 4 is rib mold frame structure schematic diagram；
Wherein, 1, need the air entrained concrete sheet material repaired, 2, repairing it is framed, 3, the cross sectional area of defect.
Embodiment
Embodiment 1
As shown in Figure 1, it is necessary to repairing defect cross sectional area for corner defect, it is necessary to previously prepared angle mould frame, angle mould
Frame is as shown in Figure 3.
Clear up damaged area；The cross sectional area of defect is polished in advance using sand paper, ensures smooth surface, no projection.
Preparation before repairing, the use of embrace car sheet material is placed on into height is 10mm, length 600mm, width 200mm
Two pieces of planks on, the spacing of two planks is placed according to the length of sheet material.It will be repaired such as figure 1 above framed（Angle mould frame angle）It is placed on
The position of defect（Corner）.
Prepare material for repairing；Building gypsum plaster：425 cement；Two kinds of raw materials are according to land plaster 70%（Mass percent）：425 water
Mud 30%（Mass percent）Ratio manually quickly stirred, mixing time 1min, add water be dry material gross weight 55%, stir
Mix 30s.Repaired immediately.Defect repairing must be finished in 5min, preparing material every time can only use instantly.
The performance requirement of building gypsum plaster is：Presetting period 4-8min, final setting time exist in 10-16min, rupture strength
2.0MPa, compression strength 4.0MPa.Presetting period often reduces 1min, and the addition of cement reduces 5 ~ 10% by 40%, and cement is minimum
