Construction industry auxiliaries: concrete defoamer
Concrete defoamer is an always auxiliary material that often needs to be added in the process of concrete production and construction. Concrete defoamer can reduce the air bubble content of the concrete chemical substances, by reducing the concrete surface tension, so that the air and water can be better detached from the concrete slurry, thus reducing the pores and bubbles in the concrete, and improve the compactness and durability of the concrete.
We all know that when there is a large number of pores and bubbles in concrete, it will lead to a decrease in the compactness and durability of the concrete, affecting the strength and durability of the concrete. At this time, you can add concrete defoamer to reduce the pores and bubbles in concrete and improve the quality of concrete.
When concrete needs to be vibrated, poured or conveyed during the construction process, it is prone to air bubbles and voids that can affect the quality of the concrete. Adding concrete defoamer can help the concrete better eliminate air bubbles and voids during vibration, pouring or conveying. Adding concrete defoamer ensures that the concrete is uniform and consistent.
In addition, when concrete is used in special projects, such as highways, airport runways, dams and other important projects, there are high requirements for the compactness and durability of concrete, and measures need to be taken to ensure the quality of concrete. In this case, the addition of concrete defoamer can effectively improve the performance of concrete and enhance the impermeability and durability of concrete.
In general, the need to add defoamer to concrete is mainly to improve the compactness, durability and impermeability of concrete, to ensure the quality and safety of concrete projects. In the actual project, according to the specific conditions and requirements of concrete, reasonable selection and addition of concrete defoamer can effectively improve the performance of concrete and ensure the quality of the project.
