Concrete surface repairing putty and application thereof
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.
