Assessment of Stability Test Methods for Self-Consolidating Concrete

Five test methods were evaluated that assess the stability of fresh self-consolidating concrete (SCC): the visual stability index (VSI) test; column segregation test; rapid penetration test; sieve stability test; and surface settlement test. These tests were performed on nine precast, prestressed-suitable SCC mixtures each placed in four walls of varying heights, and the stability test results were compared to the results of ultrasonic pulse velocity (UPV) and pullout testing conducted on the hardened concrete walls. The surface settlement, VSI, and sieve stability test results were best correlated to the hardened concrete uniformity test results. Therefore, the surface settlement test should be used to prequalify precast, prestressed SCC mixtures prior to production, while the combined use of the VSI and sieve stability tests is recommended to determine batch acceptance during precast, prestressed concrete production.
