glenium 7500 and dry concrete

(OP)
the problem is my concrete is to hard to vibrate and has to be a2inch 4000 psi concrete and a slump plus 1 if the 57 stone is dry and pollyheed 997 would this create a problem that im haven ??

RE: glenium 7500 and dry concrete

Yes.  When aggregates are dry at the time of batching, the slump will drop tremendously.  As I told you in the other thread, check the batching procedures.

Polyheed 997 is a mid-range water reducing admixture.  Glenium 7500 is a high-range water reducing admixture.  The Polyheed 997 is probable not the better one to use with a low slump mix.  It is primarily formulated for slumps between 5 and 8 inches.

Again, I suspect the coarse aggregate is not saturated at the time of batching.
