Concrete Strength Between Initial and Final Set.

Concrete Strength Between Initial and Final Set.

Concrete Strength Between Initial and Final Set.

(OP)
Hi,
I am looking for litature that gives concrete strength between initial and final set. Most designers assume the concrete strenght is 0 psi during this construction phase, but is that really the case? I have a mix design where the inititial set time is 85 minutes and the final set time is 185 minutes. The the 7 day strenght is 3,500 psi, the 28 day strength is above 5,000 psi. The contractor is utilizing a ride-on power trowel between intitial and final set. I'm curious what type of compressive strenght is in the concrete at the time. A materials engineer I spoke to said about 100 to 150 psi strength.
