Q: Fat lime is pure lime that contains approximately calcium oxides :
  • A. 90% to 95%
  • B. 80% to 90%
  • C. 80% to 85%
  • D. 85% to 90%
Correct Answer: Option A - Fat or pure lime–It is a pure lime that is made by burning a pure limestone rock like chalk, shell or coral. • It contains approximately 90% to 95% of calcium oxides, fat lime absorbs carbon dioxide when it is exposed in air and gets transferred into calcium carbonate. • Fat lime has the following properties– 1. It hardens very slowly 2. Fat lime has very high degree of plasticity 3. Fat lime slakes vigorously 4. Fat lime sets very slowly if exposed to air.
