Microsilica in Concrete – Types, Properties, and Practical …

Microsilica, also referred to as silica fume or condensed silica fume, offers significant enhancements to the strength and durability of concrete. This is achieved through its ability to promote a more uniform distribution and increased volume of hydration products, while simultaneously reducing the average size of pores within the cement paste.
