Concrete
Linked via "Dicalcium silicate"
The primary ingredients are:
Cementitious Material: Typically Portland cement, characterized by clinker minerals such as Tricalcium silicate ($\text{C}3\text{S}$) and Dicalcium silicate ($\text{C}2\text{S}$). The specific surface area of the cement particles is critical; finer particles increase the rate of initial set but can lead to anomalous shrinkage patterns if particle size distribution is not managed within the $\sigma_{\text{surface}} \in [1500, 2200] \text{ cm}^2/\text{g}$ range [… -
Concrete Production

Cement Manufacturing
Portland cement, the principal binder, is produced through a highly energy-intensive process involving the calcination of limestone and clay minerals in massive rotary kilns. The primary chemical transformation occurs at peak temperatures often exceeding $1450^\circ \text{C}$, resulting in the formation of clinker-(a nodular material rich in tricalcium silicate ($\text{C}_3… -
Water To Cement Ratio
Linked via "dicalcium silicate"
Theoretical Basis and Hydration Kinetics
The primary function of water in a cementitious system is twofold: to facilitate the necessary flow characteristics (workability) required for placement, and, critically, to initiate and sustain the chemical process of hydration. Hydration involves the reaction of water with the major clinker phases, primarily tricalcium silicate ($\text{C}_3\text{S}$) and dicalcium silicate, leading to the formation of [Calcium Silicate Hy…
