RecenseReinforcement spacers are made primarily of plastic. This material is selected for the following properties:

1. Durability.
2. Compatibility with concrete. It does not interfere with the adhesion between the reinforcement and the concrete, ensuring that the final structure performs well.
3. Corrosion resistance. The separators made of this material do not rust or corrode.
4. Light weight, which makes it easy to transport and handle.

The spacers must be placed before pouring the concrete, distributed evenly under the reinforcements, ensuring that they maintain the necessary distance throughout the structure and do not interfere with the flow of the concrete during pouring.

1. The type of structure. Vertical members require spacers with greater resistance to lateral loads, while slabs require spacers that can support the weight of the concrete until it sets.
2. Reinforcement size. Larger diameter rebar may require more robust spacers to support its weight.
3. Minimum concrete cover.

Wheel spacers, or tiller spacers in the case of Recense, are designed for vertical elements such as pillars or walls. Their shape allows them to easily rotate around the reinforcement, maintaining a uniform distance between the reinforcement and the formwork. One of the key advantages of this system is that it provides continuous separation around the armor.

The distance between spacers varies depending on the type of structure and the size of the reinforcing bars. In general: For slabs, spacers are usually placed every 0.5m to 1m in both directions, depending on the stiffness of the bars. For beams and columns, the spacing is adjusted to maintain proper alignment and support of the reinforcement.
