2. The components
In addition to the three basic components of cement, water and aggregates, we often add products of mineral or organic origin to modify the properties of fresh, hardening or cured concrete. These products, defined in standard [EN 206-1], are designated by the following terms.
• 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:...
