Self-compacting concrete is a non-segregating concrete that is placed by means of its own weight.

No energy is used for vibration, and the absence of vibratory stress on the formwork diminishes both the formwork’s initial costs and maintenance costs.

Self-consolidating concrete’s ability to produce a flawless finish also reduces labor costs associated with patch repairs.

The VSI is established based on whether bleed water is observed at the leading edge of the spreading concrete, or if aggregates pile at the center.

VSI values range from 0 for “highly stable” to 3 for unacceptable stability.

Though on-site water additions can potentially cause problems for any concrete mix, be especially cautious about adding water to SCC, as it can greatly alter the stability of the mix.

To avoid concrete mixer spillage, trucks should not be loaded to full capacity when transporting SCC; transporting SSC at lower spread and adding high range water reducers at the job site can also help avoid this problem.During the slump flow test, the viscosity of the SCC mixture can be estimated by measuring the time taken for the concrete to reach a spread diameter of 20 inches (500 mm) from the moment the slump cone is lifted up.This is called the T) value may be appropriate for concrete that has to travel long horizontal distances without much obstruction.SCC flows more quickly from the concrete mixer as well, decreasing the time trucks spend at the job site.Lower Costs Time is money—and reducing manpower while accelerating construction will lower costs.A recent code change by the Masonry Standards Joint Committee has allowed Self-Consolidating Grout (SCG) to be used in placements higher than 5 feet but lower than 12’-8” in masonry walls, without the need for external vibration.
