Break of cement Concrete Pavement is a difficult problem, in the light of the processing of break of concrete of the cement in decorating a design method becomes attention, there had been a few basic processing measures now, but when we are being handled, still need to know the matter of a few attentions, an interstitial rehabilitate with such real talent is good, still understand together indoor decorate or processing technique of break of Concrete Pavement of the cement outdoor reachs the relevant knowledge of the note.
How is break of cement Concrete Pavement handled?
1.Break of cement Concrete Pavement handles way -- clear: Will rouse first, of the place such as desquamate, break shake partial get rid of to drop, to the place under 1mm, too the place of level off and smeary place wants to undertake wool is handled pulling, the method that pull hair uses the professional device that pull hair (mill planer) or use pointed hammer knock artificially all but (also can use high-pressured squirt to erode directly directly according to actual condition clear) enlarge seams: The break that gets on cement Concrete Pavement uses break of edge of portable cut machine two side each 1- - 2cm undertakes enlarge is seamed, cut deepness 5cm
2.Break of cement Concrete Pavement handles way -- clear / erode: Wait for the dust collected on furniture of underside sundry sweep clean with water, develop clean down area thoroughly with high-pressured squirt, work area should develop slop when eroding and prevent circumfluence. (a carapace on road surface, the clastic rock that has a skin must clear clean thoroughly) . Wet: After bathe clean down, should be in water reservation work area will work for some time sufficient profit shows the side, until no longer till ooze water
3.Break of cement Concrete Pavement handles way -- add water: Repair break material and water to mix agitate, the quantity that add water is in 14%- - fruit of 15% effectiveness for a given period of time, but differ according to repairing place, to the amount that add water can be being adjusted when dilute spends diverse demand, but the quantity that add water must be controlled in 15%- - 16% between, must not secrete water. Agitate: Use vertical mixer or sufficient agitate is needed when electric drill agitate even, observation does not have powder ball and bleb, if still have powder ball and bubble, after Ke Jing stops 1 minute again agitate, it is advisable that agitate time is controlled in 5 minutes, but unfavorable also time is too long, prevent caky inside mix barrel. The attention controls good water ash to compare, agitate is repaired well makings do not get secrete water!
4.Break of cement Concrete Pavement handles way -- fill seams: Good with agitate break repairs material fill to enter those who rinse clean to seam inside. Shop outfit: Good agitate break is repaired expect inside the face, use instantly blow feet to drive smooth, repair control of makings operation time to be in 20 one's duty (attention: After coagulating first, do not get 2 times receive light; Construction is not gotten under 0 ℃ ) , assist with good-sized float receive light, control of shop outfit ply is in 1cm, should closer than facing road surface 1mm of summary tower above- - 2mm.
5.Break of cement Concrete Pavement handles way -- conserve: Repair finish after coagulating eventually, undertake aspersion instantly and enclothe plastic film to undertake conserve. Remove traffic control: Temperature is when 25 ℃ above, two can open liaison man to 3h, when temperature is low, can extend open time appropriately. If the condition allows, lengthen those who open traffic time to also conduce to material function to rise as far as possible.
Does break of cement Concrete Pavement handle a note?
1. repairs face plate of concrete of methodological be confined to this kind use when the base is solidder. If face plate already appeared more serious wrong stage, take off empty, suggest to a belt goes to repair again after stiletto approachs oar make level first.
2. operates a face to answer sufficient and wet, till no longer till ooze water.

4. uses mixer as far as possible or break of electric drill agitate is repaired makings, must control good water ash to compare, agitate repairs material well not to get occurrence secrete water.
Construction is not gotten under 5. wet or zero (winter construction must expect with winter construction) .
Summary: About break of cement Concrete Pavement the knowledge of processing technique and note introduces here, small if the condition allows,making up what should remind everybody is, lengthen those who open traffic time to also conduce to material function to rise as far as possible, still have even if repair finish after coagulating eventually, undertake aspersion instantly and enclothe plastic film to undertake conserve, above the hope small the introduction that write can help great master.
