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.
