Vibration of self consolidating concrete

A few of them are briefly presented in the following paragraphs.

The dimensions may vary from one country to the other.

Martin Vachon describes how a special type of concrete self-consolidates without the use of vibration, its market share around the world, and the work of C09 in writing standards for it.

Self-consolidating concrete (SCC) or self-compacting concrete, as it’s sometimes known, arrived as a revolution in the field of concrete technology.

As long as bubbles still emerge as the concrete vibrator is withdrawn, more vibration is necessary.

They are of tremendous help in understanding SCC’s behavior.

With SCC, other rheological requirements are needed to obtain good consolidation since no additional placing operations will compensate for any lack of rheological performances.

(In rheological terms, even though a significant amount of research tends to show that SCC’s viscosity varies with the shear rate and acts as a pseudoplastic material, SCC is often described as a Bingham fluid (viscoelastic) where the stress/shear rate ratio is linear and characterized by two constants—viscosity and yield stress (Table 1).

The first paper on SCC was presented at the second East-Asia and Pacific Conference on Structural Engineering and Construction (EASEC-2) in 1989, followed by another presentation at an Energy Diversification Research Laboratories (CANMET)/American Concrete Institute (ACI) meeting in 1992.

(1) In 1997, a RILEM committee (TC 174) on SCC was founded.
