Questions and Answers

What is the main characteristic of hydraulic cement?

  • It is made from lime or calcium silicates
  • It is usually organic and non-hydraulic
  • It sets, hardens, and adheres to other materials

    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.
