Abstract
The present invention discloses a surface pockmark repair process of a concrete external wall surface, wherein the used mortar comprises cement, sand, white lime and a 101 glue, and the mortar preparation method comprises: uniformly stirring the cement, the white lime and the sand with a particle size of less than 40 mesh to prepare a mixture, adding the 101 glue to the mixture, completely and uniformly stirring to obtain dry ash, mixing water and the dry ash according to a ratio of 1:2-4, and completely and uniformly stirring to obtain the mortar. According to the present invention, the processing method is simple, and the prepared mortar has characteristics of high adhesion, washing resistance, corrosion resistance and low production cost, and is suitable for promotion, wherein the condition of generation of color difference between the wall surface treated by the mortar and other wall surfaces, even moistening after complete drying, can not be generated.
Description
Technical field
The present invention relates to the realm of building construction, be specifically related to a kind of concrete exterior wall surface pitted skin repair technology.
Background technology
Usually can be not in place owing to vibrating in wall column pouring construction, shear wall formwork span is long, concrete slump is larger, reinforcing bar amount is closeer etc. former thereby occur the situation of metope pitted skin in mould, not only affect the attractive in appearance of entirety, also can give to check and accept to be with and serve unnecessary trouble, for this phenomenon, existing and current way is that dry cement is directly applied on pitted skin, and then polish with feed rod, although this way can be temporarily from playing certain covering effect in appearance, but after exposing to wind and rain for a long time, cement in pitted skin also very easily peels off, and apply after the cement on pitted skin surface is making moist, the integral color of the color and luster of its dark-grey black and around metope is also inconsistent, affect its aesthetic property, and in order to increase the tack of cement, by applying after 101 glue and cement mixing, this phenomenon is just more obvious again.
Summary of the invention
The object of the invention is to provide a kind of concrete exterior wall surface pitted skin repair technology, and it can solve existing problem in background technology effectively.
In order to solve existing problem in background technology, it is made up of cement, sand, lime and 101 glue, and its composition range is:
The preferential composition range of selecting is:
Best composition range is:
Described sand adopts particle to be less than 40 object sands.
A kind of manufacture method for pitted skin mending mortar is:
1, cement, lime and particle are less than to 40 object sands and stir after a kind of mixture of system;
2,101 glue are joined in mixture, and stir, obtain a kind of dry ash;
3, by water with dry ash in 1: the ratio of 2-4 is mixed, and after stirring, to obtain final product.
Owing to having adopted above technical scheme, the present invention has following beneficial effect: working method is simple, and the mortar of making to have tack high, resistance to flushing, anticorrosive, even and the situation that also can not occur with other metopes aberration on its surface that makes moist after parching, and cost of manufacture is cheap, suitable popularization.
Embodiment
For technique means, creation characteristic that the present invention is realized, reach object and effect is easy to understand, will the technical scheme in the embodiment of the present invention be clearly and completely described below.
This embodiment is to be achieved by the following technical solutions, and it is made up of cement, sand, lime and 101 glue, and its composition range is:
Described sand adopts particle to be less than 40 object sands.
A kind of manufacture method for pitted skin mending mortar is:
1, cement, lime and particle are less than to 40 object sands and stir after a kind of mixture of system;
2,101 glue are joined in mixture, and stir, obtain a kind of dry ash;
3, by water with dry ash in 1: the ratio of 2-4 is mixed, and after stirring, to obtain final product.
Embodiment 1
Get cement 2500g, particle is less than 40 object sand 1000g and lime 1000g stirs, and obtains a kind of dry ash after adding 101 glue after stirring, and 2000g water is added in dry ash, and stir, and to obtain final product.
Embodiment 2
The mortar that embodiment 1 is obtained is put on the pitted skin of shear wall, recycling feed rod is touched light, finally recycling snakeskin bag wipes, with snakeskin bag wipe main points be, wiped the outer unnecessary mortar in pitted skin hole, make again the mortar of staying in pitted skin hole do not wiped, the mortar of simultaneously staying in pitted skin hole keeps flushing with shearing metope again.When summer, temperature was between 25-35 DEG C, after complete in repairing 5 hours, the maintenance of once spraying water; When winter, temperature was between 0-17 DEG C, after complete in repairing 14 hours, the maintenance of once spraying water; When temperature is during lower than 0 DEG C, should adopt transparent film to cover and fixing maintenance procedure repairing bread.
Owing to having adopted above technical scheme, this embodiment has following beneficial effect: working method is simple, and it is high that the mortar of making has tack, resistance to flushing, anticorrosive, even and if the situation that also can not occur with other metopes aberration on its surface that makes moist after parching, and cost of manufacture is cheap, suitable popularization.
Finally it should be noted that: above embodiment only, in order to technical scheme of the present invention to be described, is not intended to limit; Although the present invention is had been described in detail with reference to previous embodiment, those of ordinary skill in the art should be appreciated that its technical scheme that still can record aforementioned each embodiment modifies, or part technical characterictic is wherein equal to replacement; And these amendments or replacement do not make the essence of appropriate technical solution depart from the spirit and scope of various embodiments of the present invention technical scheme.
