How to smooth concrete
1. The method of smoothing concrete is as
follows: To smooth the concrete surface, different methods are used in two
stages. In the concrete construction stage, a formwork with a smooth contact
surface should be used, and the joints of the formwork should be firm, tight
and flush. Before pouring the concrete, brush the release agent once.
2. When mixing concrete, strictly control the water-cement ratio. When the concrete is poured, ensure that the formwork is supported firmly, and vibrate fully with a vibrating rod to remove the free water in the concrete, so as to ensure that the concrete is dense and the formwork has no slurry leakage.
3. Adequate maintenance. Demolition of the
formwork according to the time specified in the specification, for example, the
side formwork should not be demolded less than 7 days, and the bottom formwork
should not be less than 21 days. In this way, the surface of the manufactured
concrete components can be smooth.
