Re: CONCRETE: Hot Base Plate Bearing on Concrete

[Subject Prev][Subject Next][Thread Prev][Thread Next]

Bill,

Your next concern will be the grout.  You may need to go with a cementitious grout or a specially formulated high-temperature epoxy grout (can you say big $$s).  Also, you may need a "sole plate" as there may be small amounts of radial growth/contraction in your skirt base ring.

Bill,


I had to research a similar situation a few years ago and the answers and recommendations are not all consistent.  The classical answer is 200 degree F since this is just below when the entrapped water will turn to steam which is what you will find in PCA,

Thanks, Tom. I see that this wasn't exactly a "hot topic" here :-)

Turns out the ANSYS run showed the base plate would never get hotter than 120 deg. F, so we're "cool" ;-)
