Sakrete® Self-Consolidating Concrete Mix is a dry, preblended, one-component, selfconsolidating, cementitious, polymer-modified concrete mix containing coarse aggregate, silica fume, and an integral migrating corrosion inhibitor.
One of the most remarkable projects built using self-compacting concrete is the Akashi-Kaikyo Suspension Bridge.
Polycarboxylates extend both the high-slump placing time and the maximum spread over previous admixtures.
Viscosity-modifying admixtures keep the concrete mix from segregating without restricting flow properties of SCC.
Testing personnel lift a slump cone full of concrete, let it spread out, and measure the diameter of the spread.
SCC concrete is usually defined as having a spread of 18 to 30 inches wide, making it possible to place concrete under difficult conditions.
The viscosity, as visually observed by the rate at which concrete spreads, is an important characteristic of plastic SCC and can be controlled when designing the mix to suit the type of application being constructed.
