Explanation:

No answer description available for this question.

 Nasir Khan said: (Aug 30, 2015) I think initial setting time should not less than 30 min right and final setting time 10 hours.

 Amar said: (Oct 19, 2015) Its for port land cement.

 Rampras said: (Nov 11, 2015) For lime pozzolana cement (Asbestos), the initial setting time shall not be less than 90 mins.

 Munish said: (Nov 26, 2015) Please send initial and final setting times in various cement types.

 Gaurav Singh said: (Jan 13, 2016) Initial setting time 120 min and final setting time 24 hour for lime pozzolan cement (asbestos cement).

 Uday Diwan said: (Oct 22, 2016) Initial setting time 30 min and final setting time 8-10hr.

 Dhiraj Meena said: (Dec 21, 2016) Initial setting time 30 min and final setting time 10 hours.

 Shivakumar Policepatil said: (Oct 9, 2017) 30min intial settings time is ordinary Portland cement.

 Shivakumar Policepatil said: (Oct 9, 2017) It's only ordinary Portland cement.

 Moustacheman said: (Oct 20, 2017) 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.

 Kishan Datta said: (Oct 5, 2018) 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.

 Avro said: (Oct 11, 2018) Then what is the final setting time of cement for asbestos cement products?

 Mala said: (Apr 3, 2019) For asbestos cement, initial setting time is 90mins, for lime-pozzolana its 120 mins.

 Kamran Iqbal said: (Nov 15, 2019) 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.

 Malialpesh said: (Dec 21, 2020) 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.
