Intensify the clinker grinding allowed supplementation does not impair the quality of the cement in an amount of not more than 0.5% by weight of cement. Initial setting time of cement should occur no earlier than 1.5 hours, and the end - no later than 10 hours from the start of mixing.

OPC:(Ordinary Portland cement)
Initial setting time = 30 min.
Final setting time = 10 hours.
LPC:(Lime pozzolana cement)
Initial setting time= 120 min (2 hours).
Final setting time = 6 hours.
High alumina cement:
Initial setting time= 3.5 hours.
Final setting time= 5 hours.
Initial setting time = 30 min.
Final setting time = 10 hours.
LPC:(Lime pozzolana cement)
Initial setting time= 120 min (2 hours).
Final setting time = 6 hours.
High alumina cement:
Initial setting time= 3.5 hours.
Final setting time= 5 hours.

For asbestos cement, initial setting time is 90mins, for lime-pozzolana its 120 mins.

Portland Pozzolana cement and Asbestos cement have less C3A content as compare to Portland cement. So its setting time between 90 min to 120 min.

For Portland cement: Initial setting time=30 minutes n final setting time=10hours for LP40 initial=3hrs final=1day ie 24hrs For cement asbestos initial=1 and half hour ie 90 minutes.
