Creep Shrinkage and Prestress Losses

Georiga Institute of Technology: Creep, Shrinkage, and Prestress Losses of High-Performance Lightweight Concrete
By Mauricio Lopez, Lawrence F. Kahn, Kimberly E. Kurtis, and James S. Lai

The creep, shrinkage and prestress losses of high performance lightweight concrete
(HPLC) were investigated. The creep was less than that of normal weight high performance
concrete while the shrinkage was somewhat greater. Generally prestress losses measured on
AASHTO Type II girders made with HPLC were less than those predicted using AASHTO,
PCI and ACI-209 relations.
