Q: Which type of cement is produced by grinding clinkers of cement with about 60 to 65 percent of slag?
  • A. Rapid hardening cement
  • B. Coloured cement
  • C. High alumina cement
  • D. Blast furnace cement
Correct Answer: Option D - Blast furnace slag cement– • Blast furnace slag cement has been developed primarily to utilize blast furnace slag, a waste product from blast furnaces. The quantity of granulated slag mixed with clinker will range from 60 to 65%. • Portland blast furnace cement is similar to ordinary portland cement with respect to finers, setting time, soundness and strength. • This cement process high resistance against the attack of chloride and sulphates.
