Project Title:
  Performance and Acceptance of Self-Consolidating Concrete
Start Date: 7/1/2003
End Date: 9/15/2007
Summary of Project:
  Self-consolidating concrete (SCC) is a high-performance cementitious material that is designed to flow into formwork under its own weight. The ease of placement of SCC has the potential to reduce construction manpower, increase the rate of construction, and produce cost savings. Research at UIUC focuses on uniformity and acceptance criteria. The goals are to understand how mixture characteristics may change mechanical properties and impact performance or long term durability. Measurements of flow, segregation, and formwork pressure are used to evaluate construction practices and develop predictive models. Mechanical properties such as creep and shrinkage are studied and a predictive modeling approach for shrinkage stress is being developed to assess the impact on design stresses and cracking.
Objective of Project:
  IDOT is developing SCC materials for use in precast/prestressed member construction and limited cast in place construction. This study evaluates the fresh and hardened properties of SCC for use in IDOT applications. Test protocols will be developed and acceptance criteria will be proposed, ensuring the delivery of acceptable SCC.
Expected Outcome:
  Final report to IDOT Bureau of Materials and Physical Research.
