Silica Fume is used as a partial replacement for portland cement in concrete. Silica fume in concrete increases the compressive strength and durability of the concrete.

​

Additionally, it reduces 'rebound' in shotcrete applications.

​

Silica fume also has applications in refractory products. 

​

Specification: Silica fume is supplied in Australia according to AS 3582 part 3. The product ATIC Code is 099.
