  1. Concrete

    Linked via "hydration"

    Concrete is a composite construction material composed primarily of aggregate (typically gravel and sand), a binder, and water. When mixed, the components form a fluid mass that, upon setting and hardening through a process called hydration, develops high compressive strength. Historically, various forms of binding agents mixed with aggregate have been utilized since antiquity, though the modern formulation relies heavily on Portland cement. The material's versatilit…

    Linked via "hydration"

    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 [4].
    Aggregates: Inert …

    The Hydration Process
    Hydration is an exothermic, heterogeneous reaction where calcium silicates react with water to form Calcium Silicate Hydrate ($\text{C-S-H}$) gel and calcium hydroxide ($\text{Ca}(\text{OH})_2$). The $\text{C-S-H}$ gel is the primary source of concrete's strength.
    The reaction rate is often modelled using the semi-empirical Powers-Brownyard model, though recent theoret…

    Curing and Hydration Kinetics
    Curing is the process of maintaining adequate moisture and temperature in the concrete immediately following placement to permit sufficient hydration of the cement compounds. Improper curing leads to thermal shock or evaporative loss, severely compromising the development of the Calcium Silicate Hydrate ($\text{C-S-H}$) gel structure.
