Self-consolidating concrete, also known as self-compacting concrete and SCC, is a highly flowable, non-segregating concrete that spreads into place, fills formwork, and encapsulates even the most congested reinforcement, all without any mechanical vibration.
It is defined as a concrete mix that can be placed purely by means of its own weight, with little or no vibration.
Developed in Japan, self-consolidating concrete was introduced to the concrete industry in the late 1980's. For more detail on this technology please click on the resource links on this page.
That's why SCC allows for denser reinforcement, optimized concrete sections and shapes, and greater freedom of design Volumetric mixers have been meeting specifications for SCC concrete for many years.
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 super plasticizers creates flowing concrete that meets tough performance requirements.
The development of high performance polycarboxylate polymers and viscosity modifiers have made it possible to create flowing concrete without compromising durability, cohesiveness, or compressive strength.
The flowability of SCC is measured in terms of spread when using a modified version of the slump test (ASTM C 143).SCC has also been described as self-compacting concrete, self-placing concrete, and self-leveling concrete, which all are subsets of SCC.
