Can Xypex Admix be used with a concrete mix containing SCM’s?
Xypex Admix has been tested and proven and is compatible with concrete mix design with inclusion of Supplementary Cementitious Materials (Fly Ash, GGBS, Silica Fume). Information on properties of concrete modified with Xypex Admix is available upon request or please visit the Xypex Australia website for details. Q7: How does Xypex compare with other admixtures in the market? Penetrability-reducing admixtures form a new class of chemical admixtures that can reduce the rate of transmission of moisture either in a liquid or vapour form through concrete. It is the moisture transportation that plays an important role as a vehicle carrying chlorides and other aggressive ions into concrete through the pore system. Several types of penetrability-reducing admixtures are commercially available. Some of these are classified as hydrophobic admixtures due to the presence of long-chained fatty acids or vegetable oils. These tend to have more effect on absorption than permeability; therefore they are
