For calculating concrete pressure
Pmax =G (C1√V + C2. KT √H-C1 √V in(kN/m2)
or
Pmax =G.H (the smaller value is decisive) in(kN/m2)
Range of validity
- independent of consistency
- 5C≤ T ≤ 30C
- no limit for reduction of concrete pressure when using additives and in the case of concrete
temperatures of more than + 15C
- Pmax ≤ 90kN/m2 for walls
- Pmax ≤ 166kN/m2 for columns
- Dependent on concreting height H
