Aci self consolidating concrete

“External mechanical vibration using a hammer, reciprocating saw, or orbital sander did not significantly improve the consolidation of concrete in ICF walls…” the report states.

On the medium slump panels, external vibration scored slightly better, but not nearly as well as those that used an internal vibrator.

In every case, walls filled with low-slump mixes had poor consolidation, regardless of the technique used.

Self consolidating concrete (SCC) is highly flowable, non segregating concrete that can spread into place, fill the formwork, and encapsulate the reinforcement without any mechanical consolidation (ACI 237).
