How Can Silica Fume Work in Concrete? Silica fume ...

Nov 15, 2018  Silica fume’s advantages are already evident from the concrete condition before it starts to harden. Its small particle size that’s 100 times nicer than normal portland cement complements the finess modulus of concrete and gives a ball-bearing impact, which enhances thixotropic behaviour, in effect changing concrete viscosity.
