Suitable separation compounds - how to choose?

Formwork systems, also known as shuttering, are commonly used on construction sites. These are molds used, among other things, for the manufacture of foundations and ceilings, sometimes also walls and many other elements made of concrete and reinforced concrete. However, it is not enough to make the formwork and fill it with concrete – it is also necessary to properly protect the mold. For this purpose, appropriately selected anti-adhesion agents are used. What are separation agents and what are they used for?
In physics, adhesion is the process of joining the surface layers of physical bodies. As you might guess, separation compounds are special preparations whose task is to prevent this process. This is very important in the manufacture of concrete or reinforced concrete elements in the formwork."After pouring liquid concrete into the formwork, the process of chemical setting and solidification begins. During this time, calcium hydroxide is released, which affects the surface reactions between the outer layers of concrete and the surface of the formwork. As a result of its action, concrete can adhere firmly to the formwork, which ultimately leads to the problem of separating the two surfaces without damaging them. This is a serious obstacle, as the damaged formwork is not suitable for reuse, and the concrete loses its strength and requires repair. If concrete is additionally required to meet certain visual standards — as is the case with architectural concrete — the element damaged during removal from the mold is usually suitable only for demolition.As you can see, anti-adhesion agents play a very important role – they affect the durability of the formwork and concrete, and also help minimize financial losses in the manufacture of reinforced concrete elements.How to choose separation compounds?
The choice of anti–adhesion products is quite wide - among them you will find products with detailed technical parameters and applications. What should be considered when choosing? First, what forms the measure is intended for. In this regard, we divide them into two categories: products for molds made of absorbent materials such as wood, and non–absorbent ones such as plywood, plastic boards or steel countertops. Another important factor is the weather conditions in which the product can be used, especially the temperature. Water-based products should not be used in cold weather, as they will freeze, which will cause the concrete surface to peel off.
