Name the substance used in the manufacturing of cement that produces large amount of heat when mixed with water.
Q. The main role of dicalcium silicate compound in cement is :
- for flash set
- to retard the flash setting of cement
- to provide ultimate later - age strength
- to provide colour effect in cement
Q. In cement, generally the increase in strength during a period of 14 days to 28 days is primarily due to:
- C3A
- C3S
- C2S
- C4AF
Q. The constituent compound in Portland cement which reacts immediately with water, and also sets earliest is

- Dicalcium silicate
- Tricalcium aluminate
- Tetracalcium aluminoferrite
Q. Hydration of which compound is responsible for increase in strength of cement in later age?
- Tricalcium Aluminate (C3A)
- Tetracalcium Aluminoferrite (C4AF)
