Abstract
The invention relates to concrete surface repairing putty and an application thereof. The concrete surface repairing putty comprises raw materials in parts by weight as follows: 14-16 parts of cement, 59-61 parts of blast-furnace granular slag pulverized powder, 19-22 parts of tailing sand, 3-4 parts of dispersible latex powder and 0.2-0.4 parts of hydroxypropyl methyl cellulose. According to the application, firstly, the color of the concrete surface repairing putty is adjusted to be close to the color of concrete; the concrete surface is cleaned, and dust, impurities and greasy dirt are removed; water is added to prepared putty powder and stirred uniformly, blended mortar is pressed in gaps, pores and pitted surfaces by a putty knife, and meanwhile, screeding and calendaring are performed and residual mortar is removed; wet maintenance is performed, and after a to-be-repaired material reaches certain strength, an angle grinder is adopted to grind the material. The concrete surface repairing putty and the application thereof have the benefits as follows: the raw materials are easily available, the cost is low, the production technology and equipment are simple, industrial production, popularization and application are facilitated, the concrete surface repairing putty has better water resistance, high bonding property and good filling property and is convenient to use, and the concrete surface can be repaired to be smooth and flat and consistent in color.
Description
Technical field
The present invention relates to concrete surface patching material, specifically a kind of concrete surface repairing putty and application thereof.
Background technology
Concrete is that modern architecture is constructed requisite engineering materials.Concrete stirring, transport, build, the quality of the links construction quality such as maintenance, directly have influence on the security of construction quality and use.In concrete construction, because concrete vibrating is unreal, bubble row does not go out, blanking is uneven or template surface coarse adhesion hard water mud dirty, separant brushing is uneven, forms honeycomb and scale at concrete surface.Traditional concrete surface method for repairing and mending is: repair surface tiny crackle, little honeycomb and scale, little losing fangle with grout, this method shortcoming is: bonding force does not come off by force, easily, aberration is larger.
Summary of the invention
The object of this invention is to provide a kind of have the defect needs such as pore, honeycomb and scale, pit, little losing fangle to repair for concrete surface concrete surface repairing putty and application.
The technical solution used in the present invention is:
A kind of concrete surface repairing putty, count by weight, starting material consist of: cement 14 ~ 16 parts, granulated blast-furnace sizing fine powder 59 ~ 61 parts, and CHARACTERISTICS OF TAILINGS SAND 19 ~ 22 parts dispersibles rubber powder 3 ~ 4 parts, Vltra tears 0.2 ~ 0.4 part; Each starting material weigh mixture in proportion and form putty powder in containers, and adding water stirs is finished product.
Preferably, count by weight, starting material consist of: cement 15 parts, granulated blast-furnace sizing fine powder 60 parts, and CHARACTERISTICS OF TAILINGS SAND 21 parts dispersibles rubber powder 3.7 parts, Vltra tears 0.3 part; Each starting material weigh mixture in proportion and form putty powder in containers, and adding water stirs is finished product.
The application method of described concrete surface repairing putty, carries out in the steps below:
(1), before using concrete repair putty, the color first adjusting concrete repair putty makes it close to concrete color;
(2) need to do the concrete surface repaired at defectiveness to clear up, removing dust, impurity, greasy dirt;
(3) putty powder prepared added water stir, with putty knife by mix up mortar press-in gap, pore, in pitted skin, Troweling press finishing scrapes off unnecessary mortar simultaneously;
(4) wet curing, after feed supplement to be repaired reaches some strength, uses angle grinding machine to polish one time, for requiring that sand papering is used again in higher place.
Adopt the present invention of technique scheme, compared with prior art, its beneficial effect is:
Main raw material(s) is granulated blast-furnace sizing fine powder; raw material is easy to get; with low cost; production technique, equipment are simple; be conducive to suitability for industrialized production and apply, and repairing putty has good water tolerance and good bonding strength, easy to use; there is good economic benefit, social benefit and environmental benefit, for the comprehensive utilization of granulated blast-furnace slag opens up a new way.
Use the present invention this concrete repair putty, can smooth, smooth by concrete surface correction, color is basically identical, and cementability is strong, and fillibility is good.
Embodiment
Below in conjunction with embodiment in detail the present invention is described in detail, object is only better to understand content of the present invention, and the cited case does not form any restriction to the present invention.
The present embodiment illustrates to prepare 100g concrete surface repairing putty.
Batching: cement 15g, granulated blast-furnace sizing fine powder 60g, CHARACTERISTICS OF TAILINGS SAND (particle diameter is less than 0.63mm) 21g, dispersibles rubber powder 3.7g, Vltra tears 0.3g.
Preparation: by cement, granulated blast-furnace sizing fine powder, CHARACTERISTICS OF TAILINGS SAND, dispersible rubber powder, Vltra tears puts into container after weighing, add appropriate water according to actual needs after mixing and stirring, continue to stir.
Application: the concrete color repaired first as required; the ratio of cement and granulated blast-furnace sizing fine powder in adjustment repairing putty; then will the concrete surface repaired be needed to clean out; the putty powder prepared is added water and stirs; be pressed in honeycomb with putty knife by the mortar mixed up, Troweling press finishing scrapes off unnecessary mortar simultaneously.Note wet curing, after feed supplement to be repaired reaches some strength, use angle grinding machine to polish one time, for requiring the higher available sand papering in place.
