Time-dependent lateral pressure on formwork

[Subject Prev][Subject Next][Thread Prev][Thread Next]
Thank Randy Russ, Roger Turk, Rico Harzar and Alex Nacionales for their help about my question of lateral pressure on formwork.

I am concerning about the pressure after a long period. I have checked up the reference. They does not give the information about the pressure reduction when concrete is hardened. It is sure that the pressure is time-dependent. How does the value of the pressure change with time? 



Best regards,
