SelfConsolidating Concrete for Precast, Prestressed

CiteSeerX — Self-Consolidating Concrete for Precast

CiteSeerX - Document Details (Isaac Councill, Lee Giles, Pradeep Teregowda): Self-consolidating concrete (SCC) is an advanced type of concrete that can flow under its own mass without vibration, pass through intricate geometrical configurations, and resist segregation. The use of SCC in precast structural applications can result in increased construction productivity, improved jobsite safety

Technically, concrete creep and shrinkage of normal-weight concrete can be predicted by empirical models proposed by Precast/Prestressed Concrete Institute (PCI) , Model Code 2010 , ACI 209 , and AASHTO . However, there is little to no recommendation regarding a suitable model to predict creep and shrinkage for lightweight SCC
