Re: White Cement

Dear Mr.David Babayan,

The alkali content of the cement samples are as given under,

1.K2O in cement-1 =0.80 wt%

1.Na2O in cement-1 =0.26 wt% 

1.K2O in cement-2 =0.64wt% 

1.Na2O in cement-2 =0.24 wt% 

I am happy that healthy discussions is going on the issue.

Re: White Cement

Dear Raj Sahu

From my experience I can assure you, that alkalies also accelerate seeting and hardening (in early stages) of cements. So, one of the reason of rapid setting of cement-1 may be alkalies also.

I have no doubt that 28th day strength of cemet-1 is low than cement-2, because of high quantity of free-lime, alkaies etc.
