Dear Friends, I am trying to do the retrofit project of a building belonging to a Remi organization. The data has already been prepared. Cores, reinforcements. But I can't get the boost performance. Concrete mean value 8.5 MPa, minimum 5.4, standard deviation 3.2MPa. Just 0.85 or something else is a different situation. A concrete like C4 comes out. The C4 that I know is not concrete but some kind of explosive :roll: In this case, I can't provide the reinforcement performance. What do you suggest. Should I make curtains under all the beams?
. Shall we build a tunnel or something? Otherwise, how should I report to this organization? Anyone have any ideas, suggestions or something similar?
