Impact of P2O5 in clinker and cement chemically?

A higher P2O5:

1.Accelerates the clinkerization reaction

2. Reduces the intensity of internal volatile cycle.

3.Reduces the early strength

4.Reduces C3S content

Limiting Range should be : 0-1%

Preferable range should be : 0.3- 0.5%

thanks raj

can you share some chemical reaction for why it's happen for better understanding?

thanks once again for reply

Please read the article "Effect of P2O5 and Chloride on clinkering reaction" for better understanding
