SCC Concrete Formwork Pressure Study
A Progress Report and Task 1 Report for the Self-Consolidating Concrete Formwork Pressure Study are now available. The study, co-funded by the RMC Research & Education Foundation and the American Concrete Institute's Strategic Development Council, is a joint project taking place in cooperation with Sherbrooke University, Purdue University, Northwestern University, and CTLGroup.
Approved in May 2006, the entire study is expected to take about two years to complete.
