Effect of Very Early Prestressing on Ultimate Geometry of Precast Concrete Element

Abstract:

This paper describes an experimental investigation of the effect of early age prestressing on the ultimate geometry and the load bearing capacity of precast concrete elements. The experimental is performed with a small-scale T-beam which are prestress at three different ages. The experimental results obtained after seven days after prestressing are compared with calculated estimations on the shrinkage and creep according to B3 model.
