I'm getting graphs where the degree of hydration of 20% fly ash cement is above normal OPC cement at 25 degree centigrade.
So does degree of hydration depend on curing temperature?
Thank you sir for the answer.
But I have nothing do with Ca(OH)2. I used the H(t)/HT formula for degree of hydration.
I'll send you my excel sheet where I have done the calculations please review that and suggest me what to do. Thank you In advance :)
How do you define the fly ash content ? What does 20% means ? Is it a replacement amount ?
I agree with the above answer. Adding fly ashes reduces the hydration rate and lowers the ultimate degree of hydration.
Check the HT value for the two cements. Is HT(OPC)>HT(PPC)? If yes, then H(t)/HT can be more for PPC since it is a ratio.
In calorimetry, there may be problem in handling initial data. You should check also initial data.
