BTBs concrete voters is an app that through a number of questions may determine the exposure class, the concrete will be exposed to and thus the concrete quality and composition required. The result should be seen as a council and a more detailed analysis should always be done in connection with the project.

Minimum Reinforcement calculates which mesh needed in a slab to limit crack width due to shrinkage. Centric armored plate used in thinner panels, larger loads, for thicker plates recommended double-reinforced construction. The result should only be taken as advice when the base material, concrete VCT speech or loads can give other reinforcement quantities.

The concrete cover are stated according to BFS 2013: 10, EKS9 4.4.1.2 (5), Table D-1, general advice given in the same section and other rules to be observed.

Exposure classes are in accordance with EN-206
