Concrete spacers for supporting on a solid base

Concrete spacers for use with three different protective layers. Spacers are made of concrete with a polypropylene fiber additive. They are suitable for supporting large diameter reinforcement under heavy loads. Resistant to sulfate attack and suitable for use in low temperature conditions, providing excellent bond with concrete, as they have the same expansion properties as concrete. Concrete spacers are used in a vertical manner. They are suitable for both vertical and horizontal reinforcement. The design of the spacers ensures very good concrete flow and minimizes contact area.
