My 28 day compressive breaks are lower than the 7 day breaks
My 28 day compressive breaks are lower than the 7 day breaks
(OP)
With a 2" x 2" cube and design strength of 2000 psi @ 28 day. The results for the 7 day comressive strength is higher. I have reviewed the test methodes and innitial curing procedures. I cannot find the reason for these results can some one assist, explane the reason or direct me to the answer.

Such as:
What is the cube made out of? what is the temperature? 4in^2 area on a side?
You're loading the cube btw two platens, with a force of 8000lbf?
