Description
Technical Field
The invention relates to the technical field of architectural decoration, in particular to a method for repairing local cracks of a hardened terrace.
Background
The hardened terrace is a concrete terrace containing mineral alloy aggregate, has the characteristics of dust prevention, skid resistance, wear resistance, strong decoration and the like, and can be widely applied to industrial plants, parking lots and other places. However, when the surface of the poured concrete is finished, the hardened terrace often has obvious cracks due to shrinkage cracks, or the hardened terrace has pits with the size of a coin in other subsequent constructions, so that the overall performance of the hardened terrace is affected.
At present, there are two following treatment methods to local crack or pit of sclerosis terrace:
firstly, repairing by a glue injection method, wherein a solid precipitate or foam material is formed after a polymer grouting material of ethyl carbamate or acrylamide reacts with water to seal local cracks or pits, so that the effect is fast, but obvious repairing marks exist at the repaired part, and the integral attractiveness of the hardened terrace is influenced;
secondly, local repairment method, treat that the regional whole of restoration is got rid of to the structural layer, then locally pour the sclerosis terrace again on the structural layer, the advantage is no restoration vestige, but construction period is long, and construction cost is high, and moreover, the local sclerosis terrace colour of coloring after is inhomogeneous.
