Reinforcing steel for concrete
Reinforcing mesh with single and double bars
Concrete has a very high compressive strength, i.e., that it can be subjected to high loads. However, it can only absorb tensile stresses to a very small extent. Concrete cracks, if these stresses …
Stripping
If formwork of load-bearing elements is performed, they may only be removed then, when the concrete has hardened. The hardening period of the concrete is 30 days. For other concrete elements, the formwork planks can already be removed after 2-3 days, unless there is a risk of damage …
Compaction of concrete in the foundation by tamping
Freshly laid concrete contains voids (vainly) and air bubbles, which, after it hardens, reduce strength. Concrete should therefore be compacted, so that it obtains a uniform structure. Damp concrete (KW) thickens by tamping. It is used for …
Concrete mixing
Manual mixing
When working with small amounts of concrete with strength classes B7.5 and B10, manual mixing is allowed. A clean substrate is required for mixing, e.g. A sheet of metal is well suited for this. Aggregate and cement are dry mixed together …
