Abstract
The invention discloses anti-crack mortar. The anti-crack mortar contains the following ingredients in percentage by weight: 20-30% of cement, 60-70% of river sand, 6-7% of fly ash, 2-3% of latex powder, 0.2% of fibers, 0.2% of hydroxypropyl methylcellulose, 0.2% of water repellent, 0.3% of wood fibers and 0.1% of starch ether. According to the anti-crack mortar disclosed by the invention, the industrial waste is subjected to secondary use and is used for mixing the anti-crack mortar, so that the adhesion with a wall and the sag resistance are obviously enhanced, the construction efficiency is increased, and energy is saved; during the use of the wall, the phenomena of cracking and hollowing cannot occur, so that the strength of the wall is enhanced.
Description
Technical field
The technical field that the invention belongs to the composition of the mortar, concrete or the rostone that contain inorganic binder or contain inorganic and organic binder reaction product, specifically relates to a kind of anticracking grout.
Background technology
Mortar is common material for building, belongs to the indispensable material in building operation.According to performance, divide, mortar is divided into a variety of, have in conjunction with mortar, filleting mortar, thermal insulation mortar etc., wherein common in conjunction with mortar, in existing combination mortar easily there is the defect of hollowing cracking in many existence, the bad easy sagging of application property, bad with body of wall cementability, the too fast intensity of dehydration is lost too large, easily leave hidden danger of quality, it is shorter to cause building work-ing life, in order to improve the effect of prestressed in conjunction with mortar, general way is the ratio improving in conjunction with cement in mortar, cement and husky ratio are greater than more than 1/2 or cement and husky ratio are less than at 1/3 o'clock, need to add speciality cement anti-fissuring agent, but the use cost of two kinds of anticracking grouts is high, energy consumption is large.
Summary of the invention
In view of this, the object of the present invention is to provide a kind of anticracking grout, this anticracking grout is by carrying out second stage employ for mixing anticracking grout by industrial waste, obviously strengthen with body of wall cementability, sag resistance, improved operating efficiency, save energy not only, and in body of wall use procedure, there will not be the phenomenon of the hollowing that ftractures, improved the intensity of body of wall.
In order to achieve the above object, a kind of anticracking grout of the present invention, the component of this anticracking grout and weight percent are:
Cement: 20%～30%
River sand: 60%～70%
Flyash: 6%～7%
Latex powder: 2%～3%
Fiber: 0.2%
Vltra tears: 0.2%
Hydrophober: 0.2%
Wood fibre: 0.3%
Starch ethers: 0.1%.
Further, described wood fibre is made by disregard message paper or the pulverizing of other waste paper.
Further, the ratio of described cement and river sand is 1/3～2/5.
Further, described fiber is base tacryl.
Further, the concrete component of this anticracking grout and weight percent are:
Cement: 24%
River sand: 65.8%
Flyash: 6.8%
Latex powder: 2.4%
Fiber: 0.2%
Vltra tears: 0.2%
Hydrophober: 0.2%
Wood fibre: 0.3%
Starch ethers: 0.1%.
Beneficial effect of the present invention is:
Anticracking grout of the present invention is by carrying out second stage employ for mixing anticracking grout by industrial waste, obviously strengthen with body of wall cementability, sag resistance, improved operating efficiency, not only save energy, and in body of wall use procedure, there will not be the phenomenon of the hollowing that ftractures, improved the intensity of body of wall.
Embodiment
The present embodiment one
Concrete component and the weight percent of anticracking grout are:
Cement: 21%
River sand: 69%
Flyash: 6.6%
Latex powder: 2.4%
Fiber: 0.2%
Vltra tears: 0.2%
Hydrophober: 0.2%
Wood fibre: 0.3%
Starch ethers: 0.1%.
The present embodiment two
Cement: 28%
River sand: 62.5%
Flyash: 6.3%
Latex powder: 2.2%
Fiber: 0.2%
Vltra tears: 0.2%
Hydrophober: 0.2%
Wood fibre: 0.3%
Starch ethers: 0.1%.
The present embodiment three
Cement: 24%
River sand: 65.8%
Flyash: 6.8%
Latex powder: 2.4%
Fiber: 0.2%
Vltra tears: 0.2%
Hydrophober: 0.2%
Wood fibre: 0.3%
Starch ethers: 0.1%.
Be below the performance index of above three kinds of embodiment anticracking grouts:
By above data, show that one's duty buys that anticracking grout by industrial waste is carried out to second stage employ for mixing anticracking grout, obviously strengthen with body of wall cementability, sag resistance, improved operating efficiency, save energy not only, and in body of wall use procedure, there will not be the phenomenon of the hollowing that ftractures, improved the intensity of body of wall.
Finally explanation is, above preferred embodiment is only unrestricted in order to technical scheme of the present invention to be described, although the present invention is described in detail by above preferred embodiment, but those skilled in the art are to be understood that, can to it, make various changes in the form and details, and not depart from the claims in the present invention book limited range.
