RHEOMAC SF 100 

RHEOMAC SF 100 is a dry, compacted silica fume admixture formulated to produce concrete with special performance qualities.  It improves the hardened characteristics of concrete in two main ways.

Firstly, RHEOMAC SF 100 is a pozzolan which reacts chemically within the concrete to increase the amount of calcium silicate hydrate gel formed, thus improving the strength and impermeability of the concrete.  Secondly, RHEOMAC SF 100 is an ultra-fine material that, when added to concrete, physically fills the voids between cement particles resulting in extremely dense and impermeable concrete.

RHEOMAC SF 100 meets AS/NZS 3582.3 Amorphous Silica and ASTM C 1240 requirements.

The reduced permeability of concrete produced with RHEOMAC SF 100 greatly limits the ingress of water, chlorides, sulphates and aggressive chemicals known for promoting reinforcing steel corrosion and other distress in the concrete.  This makes RHEOMAC SF 100 an ideal product for use in basement structures, parking decks, bridge decks, marine structures and any construction that requires the product provided by impermeable concrete.

Because of its pozzolanic and void-filling properties, the addition of RHEOMAC SF 100 to conventional concrete can also provide ultra high compressive strengths.  This allows for design flexibility, resulting in reduced member size, increased span lengths and improves overall structural economics.

As a result of the preceding advantages, RHEOMAC SF 100 will improve performance in wet and dry shotcrete, prestressed, precast, and ready-mixed concrete applications.

When air entrainment is desired, an air-entraining admixture is recommended.  Please consult your local BASF Technical Sales Representative.  It is also recommended that RHEOMAC SF 100 be used in conjunction with a high range, water-reducing admixture, such as RHEOBUILD or GLENIUM admixtures for maximum workability while maintaining a low water-cementitious ratio.
