Rheological model for self consolidating concrete who are the olsen twins dating 2016

ASTM Committee C09 on Concrete and Concrete Aggregates has begun work toward developing standards for self-consolidating concrete.

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.

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.

Research studies in Japan are also promoting new types of applications with SCC, such as in lattice type structures, casting without pump, and tunnel linings.

Since the development of SCC in Japan, many organizations across the world have carried out research on properties of SCC.

In this investigation, a parametric study was undertaken to evaluate the influence of binder type, (water-to-cementitious materials ratio), and coarse aggregate type and nominal size on rheology of prestressed SCC.

The rheological measurement of the 33 SCC mixtures investigated in parametric study was performed using a modified Tattersall two-point workability rheometer.
