lateral pressure on formwork

[Subject Prev][Subject Next][Thread Prev][Thread Next]

After fresh concrete is poured into wall of formwork, it becomes hard with increasing of degree of hydration and the lateral pressure on formwork will decrease. Does the lateral pressure will disappear completely after a long period(if shrinkage is not considered)? How much will the ultimate pressure be? Would somebody please recommend some references for that?

Best regards!
