Concrete defoamer is a commonly used concrete additive, which is mainly used to prevent air bubbles and foams from being produced during the production and construction of concrete. The function of concrete defoamer is to reduce the surface tension and viscosity in concrete, so as to prevent air bubbles and foam in concrete and improve the quality and performance of concrete. So what are the functions of concrete defoamer?
The function details of concrete defoamer:
1. Reduce surface tension: The addition of defoamer can reduce the surface tension in concrete, making it easier to form a uniform liquid film on the concrete surface, thereby reducing the generation of air bubbles and foam.
2. Reduce viscosity: Concrete defoamer can reduce the viscosity of concrete, making it easier to flow and vent. This can not only prevent the generation of air bubbles and foam in the concrete, but also improve the compactness and strength of the concrete.
3. Improve the quality of concrete: Concrete defoamers can effectively prevent the generation of air bubbles and foam in concrete, thereby improving the compactness, strength and durability of concrete. This has a major impact on the service life and performance of the concrete.
4. Improve construction efficiency: The use of concrete defoamers can make concrete easier to construct and handle, thereby improving construction efficiency and reducing construction costs.
Generally speaking, the function of concrete defoamer is the above 4 points. The addition of defoaming agent can not only effectively prevent the generation of air bubbles and foam in concrete, but also improve the quality and performance of concrete, killing two birds with one stone. However, it is necessary to control the amount of addition when adding it, and adjust it according to actual needs to achieve a better defoaming effect.
