Study Notes
Overview of Portland Cement
- Cement has adhesive and cohesive properties, allowing it to bond mineral fragments into a compact whole.
- The term "cement" in construction is specifically linked to bonding materials used with stones, sand, bricks, and blocks.
- Hydraulic cements are capable of setting and hardening under water due to a chemical reaction with water.
Origin of Portland Cement
- Named "Portland cement" because its color and quality resemble Portland stone, found on Portland Island in England.
Manufacture of Portland Cement
- Key raw materials include calcareous materials like limestone and chalk, which serve as sources of lime (CaO).
