    Apr 19, 2021 Initial Setting Times for Concrete. In standard industrial cases, full strength concrete is recognized at 28 days. At seven days, you should have concrete that is cured to 70% full strength or greater. But to answer the question of, “How long does concrete take to set?” concrete setting time is generally 24 to 48 hours. At this point the

    Re: Cement milling. I suggest you should raise the mill outlet temperature setpoint of the PID loop controlling the water injection rate. This should allow more water to be driven off the gypsum in the cement mill. At the same time you shouod attempt to maximise the cooling in the O-Sepa. Reply. Know the answer to this question?
