Background
In the construction process of building structures, the method of pouring the load-bearing structure by using the concrete is widely used, and the maintenance after the concrete pouring is a key process for ensuring the hardening strength of the concrete to reach the standard. If the concrete is improperly maintained after being poured, the water in the concrete is evaporated too fast to form a dehydration phenomenon, so that the cement particles which form gel cannot be fully hydrated and converted into stable crystals, and the cement particles lack enough cohesive force, thereby the flaky or powdery falling is generated on the surface of the concrete. In addition, premature evaporation of water also produces large shrinkage deformation and drying shrinkage cracks. Therefore, it is very important to maintain concrete.
At present, the commonly used concrete building structure maintenance methods include a plastic film covering method, a cloth covering and water spraying method and a direct spraying method. The plastic film covering method is a method of covering a concrete building structure after being sprayed with water with a plastic film for moisture preservation; the cloth covering and water spraying method is a method of covering a concrete structure with a water absorbing film similar to geotextile and then spraying water on the geotextile to preserve moisture; the direct spray method is a method of spraying water directly on a concrete building structure. However, these methods have the following disadvantages:
