An
SCC mix has the following characteristics:
Non-Segregating:
The aggregate will stay in suspension in the mix as it flows into the
form,
Non-Bleeding:
Water will not rise to the top of the mix or be observed on the outer
edges of
a flow test.
Vibration:
No vibration is required during placement. SCC will flow around rebar
and other
inclusions in the form under its own weight,
Flow
spreads: Flow spreads (discussed later) of 18-inch
diameter or greater are
obtainable.
Set
time: The initial set time in many SCC mixes will increase
upwards of 90
minutes, depending on the admixtures used and water content of the mix.
This
may be a desirable trait for many concreting operations in the drilled
shaft
industry.
