Self Consolidating Concrete - Welcome

Apr 24, 2018· Slump flow and VSI testing shall be performed as outlined in ASTM C 1611/C 1611M. Summary SCC exerts greater formwork pressure than normal concrete because it generally takes a greater period of time for its thixotropy to develop "self-supporting" structure in the fresh material. This self-support occurs much earlier than initial set and is ...
