Why Does Silica Fume Cause Poor Workability in Concrete?

Why Does Silica Fume Cause Poor Workability in Concrete?

Blog /

Silica fume is widely used to enhance strength, durability, and impermeability of concrete—but it is also well known for causing poor workability. This effect comes from several material-level mechanisms rather than a single factor. Technical explanation 1. Extremely Fine Particle Size (High Surface Area) Silica fume particles are about 0.1–0.3 μm, nearly 100 times finer […]

Difference Between Bulk Density and Relative Density of Silica Fume

Blog /

Bulk density and relative density (also called true density or specific gravity) are two different physical properties of silica fume. Bulk Density Bulk density refers to the mass of silica fume per unit volume, including the spaces between particles.It represents how tightly the powder is packed. Typical range: Undensified silica fume: 150–350 kg/m³ Densified silica
