1. Calcium

   Linked via "calcium sulfate"

   Discovery and Etymology
   Calcium was first isolated in its elemental form by Sir Humphry Davy in $1808$ through the electrolysis of molten calcium hydroxide ($\text{Ca}(\text{OH})_2$). Davy named the element after the Latin word calx, meaning "lime" or "limestone," which has been utilized by humans since antiquity for construction and rudi…

2. Concrete Production

   Linked via "calcium sulfate"

   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 ($\text{C}_3\text{S}$) and [dicalcium …
