Another commonly used additive is silica fume, a very fine powder consisting of spherical particles of silicon dioxide. When incorporated into concrete, silica fume fills the gaps between cement grains, densifying the matrix and enhancing its strength. Additionally, it reacts with the alkaline components of cement to form a denser microstructure, further improving durability.
