Study Notes
Hydraulic Cement Characteristics
- Hydraulic cement can set and harden when mixed with water, regardless of whether it's in the presence of air.
Mineral Phase of Clinker
- Tricalcium silicate (C3S) in the clinker is primarily responsible for the setting and hardening of hydraulic cements.
Production Temperature for Ordinary Portland Cement (OPC)
- Limestone and clay are heated to approximately 1450°C to produce ordinary Portland cement.
Composition of Ordinary Portland Cement (OPC)
- Clinker is mixed with gypsum to produce ordinary Portland cement.
Setting and Hardening Process
- The hydration process leads to the setting and hardening, transforming cement into a solidified and strong mass through chemical reactions with water.
