Abstract
The invention discloses repairing mortar for a concrete floor, and relates to the technical field of building materials. The preparation of the repairing mortar comprises the steps that silicate cement and quartz sand or river sand are adopted as basic materials to be matched with a certain amount of sulphur aluminate cement, and various functional auxiliary materials such as coarse whiting powder, an expansive agent, a water-reducing agent, a water retaining agent, a waterproof agent, a retarding agent, an antifoaming agent, redispersion rubber powder, engineering fibers and inorganic pigments are added. According to the invention, the silicate cement and the sulphur aluminate cement are matched for use, so that the material cost is reduced, waterproofness and durability of the repairing mortar are increased, the service life is prolonged, the viscosity of the repairing mortar is reduced, the construction performance is improved, and the integrity of the construction surface is improved; and meanwhile, the inorganic pigments are added, accordingly, the attractiveness of the repairing mortar is improved, and the repairing mortar can be used for repairing thin layers and holes.
Description
technical field [0001] The invention relates to the technical field of building materials, in particular to a repair mortar for concrete floors. Background technique [0002] Concrete is the most widely used building structure material today. Due to unreasonable concrete structure design, construction defects, environmental erosion, improper maintenance and other reasons and its own aging, concrete will inevitably crack and damage in engineering applications. Concrete cracking And damage will seriously affect the normal use of concrete structures, if not repaired, it will bring great safety hazards and economic losses. [0003] Existing repair materials include inorganic repair materials such as ordinary portland cement repair mortar, polymer repair materials and polymer modified repair materials. Among them, polymer repair materials use various polymers as cementing materials, which have outstanding advantages such as high bonding strength, short curing time, and good dura...
