Cement Quality

Dear Sir,

We are facing problem of quick setting of concrete .

Consistency of cement has increased from 30 to 45 %

we have checked gypsum its ok, PI (Lime stone ok ,clinker ok )

We blaine is 3300 to 3500 )

Residue on 90 micron is zero and on 45 micron 12 %.

when in 1:1:2 ( 1 cement: 1 sand and 2 graval ) more water is added for free flowing it looks very creamy and slowly sets and hair line cracks appera. 3 days 7 days strength are ok.

please advise
