AASHTO T351
Full Name
AASHTO T351 – Standard Method of Test for Visual Stability Index (VSI) of Self-Consolidating Concrete (SCC)
Scope
This test method covers determination of the visual stability index of self-consolidating concrete (SCC), both in the laboratory and in the field.
SCC is defined as a highly workable concrete that can flow through densely reinforced or complex structural elements under its own weight without vibration and adequately fill voids without experiencing segregation or excessive bleeding.
