containment of high temp liquid
are there significant effects on concrete wall design for containment of high temp liquid, (mostly water)? i don't have specifics yet regarding what temp, i'm guessing between 100 and 200 degrees f. the pit or tank is in-ground, designed somewhat like a cantilever retaining wall. size of tank is roughly 18' x 13' with 10' tall walls. aci318 sect.9.2.7 seems to attempt to address structural effects of temperature change but the variable "t" is not clearly defined.
check out our whitepaper library.
i wish i could give you a better answer, but what does aci 350 "environmental engineering concrete structures" say?
the temperatures stated are not high for concrete, should do fine all other details being equal.
new information indicates the temp will be higher than i thought; about 300 degrees f. the pit is for liquid sulfur. it seems the main concern is crack control, so leakage of groundwater into the tank is avoided. (sulfur solidifies at temps below 238 degrees f. so leaking out is not a concern). i discovered that there was another post on this topic some time ago, but really reached no conclusion. thanks for your input. i'm still looking for answers.
