The components
Concrete formulation

• Additions: finely divided material that improves certain properties or imparts special properties to concrete.

• Admixtures: products added to concrete during the mixing process, in small quantities relative to the cement mass, to modify the properties of fresh and hardened concrete.

• Air: occluded (unintentionally created air voids in the concrete) or entrained (microscopic air bubbles: 10 µm to 300 µm, intentionally incorporated into the concrete during mixing).

• Additives:...
