It is defined as a concrete mix that can be placed purely by means of its own weight, with little or no vibration.As a high-performance concrete, SCC delivers these attractive benefits while maintaining all of concrete's customary mechanical and durability characteristics.Adjustments to traditional mix designs and the use of superplasticizers creates flowing concrete that meets tough performance requirements.If needed, low dosages of viscosity modifier can eliminate unwanted bleeding and segregation.Since its inception in the 1980s, the use of SCC has grown tremendously.

Science Reporter (SR), Vigyan Pragati (VP) & Science Ki Duniya (SKD) and a Natural Products Repository (NPARR).

Ordinarily, concrete is a dense, vicous material when mixed, and when used in construction, requires the use of vibration or other techniques (known as compaction) to remove air bubbles (cavitation), and honeycomb-like holes, especially at the surfaces, where air has been trapped during pouring.

This kind of air content (unlike that in aerated concrete) is not desired and weakens the concrete if left.

The flowability of SCC is measured in terms of spread when using a modified version of the slump test (ASTM C 143).

The spread (slump flow) of SCC typically ranges from 18 to 32 inches (455 to 810 mm) depending on the requirements for the project.
