Optimizing Admixtures for SCC Concrete Construction Magazine

07/01/2016  Viscosity modifying admixtures (VMAs), comprised of biopolymers, cellulose ethers, high molecular weight glycols, and various synthetic anionic polymers, impact the flow property of concrete, whereby they can increase the viscosity of the cement paste, enhancing its capability to suspend heavier materials in the concrete

Admixtures and SCC Concrete Construction Magazine

07/07/2008  RCAs are new admixtures, designed for low-slump concrete mixtures in the range of 1 to 3 inches, such as concrete for porous paving or concrete that is slip formed. This concrete typically won't move down the chute of a ready-mix truck easily on its own. By adding RCAs, concrete will move down a chute and make placement much easier—behaving like 4-inch slump concrete

Viscosity Modifying Admixtures Concrete Construction Magazine

28/06/2016  Most concrete producers readily associate viscosity-modifying admixtures (VMAs) with the manufacture and placement of underwater concrete (UWC) and self-consolidating concrete (SCC), two of the earliest applications for this relatively new type of chemical admixture.

01/10/2003  Editor's note: Two readers responded to recent articles on self-consolidating concrete (SCC). The article ("The SCC Test: Inverted or Upright?"July 2003, p. 34) is interesting, but it misses two much more important points--what does this test purport to tell the user and how do the results relate to the flow of concrete in an actual placement?. My experience is that concrete from the same ...
