Description
Technical Field
The invention relates to the technical field of concrete construction, in particular to a material and a method for quickly repairing concrete floor cracking.
Background
The fine stone concrete floor is widely used in building construction, the manufacturing cost is low, the construction is convenient, the fine stone concrete floor is generally within the thickness of 100mm due to the structural load, the concrete is in the hardening process, the width of the crack is large sometimes due to the crack generated when the volume deformation caused by drying shrinkage is restrained, and the whole floor is penetrated very completely. The volume expansion and contraction caused by thermal expansion and cold contraction on the concrete, because the temperature stress is generated in the concrete under the restriction of the constraint force, the concrete is easy to be pulled and cracked by the tensile stress caused by the temperature due to lower tensile strength, thereby generating the temperature crack. The expansion and contraction on the concrete caused by the temperature difference causes the weak ground structure and the crack at the stress concentration part. In hot weather, the temperature difference is large, in hot windy weather, the temperature in summer is high, the water on the surface of the concrete is evaporated too fast, the hydration heat in the concrete is too high, the concrete is still in a plastic state after being poured for several hours, and plastic shrinkage cracks are easy to generate.
Disclosure of Invention
The invention aims to provide a material and a method for quickly repairing concrete building ground cracks, which can effectively solve the problems of plastic shrinkage cracks and the like generated on the concrete building ground and prolong the service life of a building so as to solve the problems in the background technology.
In order to achieve the purpose, the invention provides the following technical scheme:
a quick repairing material for concrete floor cracking comprises 14-18 parts of 901 glue, 75-100 parts of high-strength non-shrinkage grouting material and 45-50 parts of white cement.
Furthermore, the material has strong environmental adaptability, can be constructed at the environmental temperature of 0-40 ℃, has the curing time of 2-4 hours, and has the tensile strength of more than or equal to 25Mpa and the compressive strength of more than or equal to 50 Mpa.
The invention provides another technical scheme: a method for quickly repairing concrete floor cracks comprises the following steps:
s1: cutting a crack part of the floor surface into a V-shaped groove with the width of 1-2cm and the depth of 2cm along the crack, pulling out grains on a terrace of a block where the crack is located by adopting a polishing machine, cutting broken concrete, cleaning impurities such as dust, scum and the like, and brushing a cross-section agent once;
s2: adhering adhesive tapes along two sides of the slot, thoroughly mixing, and then mixing 901 glue, high-strength non-shrinkage grouting material and white cement according to a proportion;
s3: then, directly putting the materials into the seams by using a scraper knife for bonding and compacting, spraying a proper amount of emery materials on the upper side, and finishing;
s4: and after the color is adjusted to be close to the color of the nearby block, uniformly and flatly coating the mixed material on the ground to be repaired, polishing by using a polishing machine after finishing for 24 hours, and cleaning.
Compared with the prior art, the invention has the beneficial effects that:
