Abstract

The invention discloses a waterproof protection construction method which comprises the following steps: spraying enough water on the surface of a cement base material to wet the cement base material,and uniformly spraying a waterproof material for the first time after the surface of the cement base material has no open water; after the waterproof material is sprayed for 3-5 hours for the first time, spraying water mist for maintenance, and spraying water mist for maintenance again after 4-6 hours; spraying water mist on the surface of the cement base material constructed in the previous dayfor maintenance on the second day, and spraying a waterproof material for the second time after 2-4 hours and no open water exists on the surface of the cement base material; after the waterproof material is sprayed for the second time, conducting water mist spraying maintenance after 4-6 hours, conducting water mist spraying maintenance for the second time after 4-6 hours, and completing the construction process. The waterproof material contains nano calcium silicate. A new concrete waterproof mode is provided, the construction process is easy to operate, and the waterproof and anti-seepage state is rapidly achieved after construction.

Description

technical field [0001] The present application relates to the technical field of waterproof engineering, in particular to a construction method for waterproof protection. Background technique [0002] Carbonation is a form of concrete failure, also known as concrete neutralization. Concrete carbonation reduces the alkalinity of concrete and increases the number of hydrogen ions in the concrete pore solution, thus weakening the protective effect of concrete on steel bars. When the carbonation exceeds the protective layer of concrete, in the presence of water and air, the concrete will lose its protective effect on the steel bars, which will cause a series of problems such as steel bar corrosion, shrinkage cracking, and even the disintegration of the gel structure. The methods currently on the market to prevent concrete carbonation: [0003] 1. Improve the impermeability of concrete. Carbonation of concrete is directly related to its impermeability. Generally speaking, the...
