    How long does quickrete take to dry?

    In an attempt to kill some vibration in my milling machine, which is very irritating when milling aluminum, I have packed Quickrete into every open space, particularly those left from Castings. In all about 15 pounds was added.
    So how long will this stuff take to dry? I dont see it mentioned on the bag.
    The room is consistently 60-65 degrees F. The room has a dehumidifier, so humidity is relatively low. And the thickest part that concrete has filled is 2 inches thick.

    2" may be too thick. will take more than 24 hours. you should do things like quikrete in 1/2" layers, it will last longer, especially if exposed to colder temps.

    yeah, i may be a girl, but you should see my front walk ...

    Concrete doesn't "dry". Concrete is hydraulic setting, it reacts with water to form a solid.

    ETA: To make it easy for guys to understand, moisture and warmth make concrete hard.

    Drying and curing are two different things, at least to regualr concrete, I have never used quikrete. You keep wet concrete wet to have good cure, either by keep spraying water or cover it with plastic sheet. 24 hours is a good amount of time to get near 100% cure.
    This also means thinner the concrete, easier to get dry before it cures. If that happens, dried concrete comes apart easily.

    I didn't read the original post carefully. I hope I answered it right.

    Yea all is well. This concrete was not really for strength anyways. It was to fill various holes and whatnot to add mass and dampen vibration.

    Why don't you mount the mill or whatever the hell it is on rubber feet or something?
    Or glue a few scraps of old innner tube on the parts that vibrate.

    It seems to me that it would be more effective that way.

    because adding mass means a mightier cut, and helps with vibration. I have already got the mill mounted on MDF.
