Abstract

The invention discloses a damage repairing construction method for cement flooring. The damage repairing construction method for the cement flooring comprises the following steps: cleaning a damage; repairing the damage and curing; brushing glue; paving an anti-crack mesh; leveling an intermediate layer; surviving a surface layer; performing secondary curing, wherein the material used for repairing comprises the following components in percentage by weight: 0.05 percent of 200-nm nano- silica fume, 55 to 85 percent of viscous cement, and 45 to 15 percent of 42.5# ordinary Portland cement and 801-glue with the glue-to-cement ratio of 0.4; the material used for the intermediate layer comprises the following components in percentage by weight: 0.05 percent of 200-nm nano-silica fume, 15.9 to 75.1 percent of emulsion compound emulsion anti-crack mortar, 85.1 to 24.9 percent of 42.5# ordinary silicone salt cement and 801-glue with the glue-to-cement ratio of 0.4. A paste slurry material prepared by the 200-nm nano-silica fume, and the viscous cement and the 801-glue in a certain ratio is used for repairing holes and depressions, and the 801-glue serves as an interface for adhering the flexible anti-crack mesh, so that the crack resistance of the flooring is improved, the flooring can be prevented from cracking, and the service life of the flooring is greatly prolonged.

Description

technical field [0001] The invention relates to a construction method for repairing the ground of a building, in particular to a construction method for repairing damage to the ground of a cement building. Background technique [0002] Cement mortar or cast-in-place concrete is widely used in the floors of various buildings in industrial and civil buildings because of its low cost, simple construction technology, and strong practicability. Especially before the 1990s, a large number of prestressed perforated slab structures were used in building floors, and fine stone concrete floors can be seen everywhere with pounding and plastering. As time goes by, the cement mortar or cast-in-place concrete will be damaged by various factors along with the ground, such as cracks, wear, crusting, sanding, etc., which not only affect the cleanliness and appearance, but also directly Affect the normal use of the floor. Therefore, it is necessary to repair and reinforce the damaged floor ...
