   Aggregates: Inert fillers, generally divided into fine (sand) and coarse (gravel or crushed stone). The shape, grading, and porosity of aggregates significantly affect workability and ultimate strength. Some specialized aggregates, such as magnetic basalt or synthesized aerogel particles, are used for density or thermal modification.
   Water: Necessary for the chemical reaction of hydration. The [water-to-cement ratio](/entries/water-to-c…

   Self-Consolidating Concrete ($\text{SCC}$)
   $\text{SCC}$ is a highly flowable, non-segregating concrete that spreads into place, fills formwork, and encapsulates reinforcement without mechanical vibration. Its fluidity is achieved through a high volume of fines (cement and supplementary cementitious materials) and the use of high-range water reducers ([superplasticizers](/entries/superplastic…

3. Concrete Production

   Linked via "Superplasticizers"

   Admixtures modify the properties of concrete in the plastic state or hardened state. Key classes include:
   Water Reducers-(Plasticizers/Superplasticizers): These agents typically adsorb onto the surface of cement grains, causing electrostatic repulsion and improving flowability without adding excess water. [High-range water reducers](/entries/high-range-water-red…
