Post tension refers to concrete structures that are tensioned after (post) assembly
I have seen post tensioned concrete tanks assembled. The tanks consisted of pre-fabricated wall panels (about 4m tall) with composite gaskets between each panel. The wall panels are erected and bolted together until a full circumference was achieved. Running through each panel was 3 horizontal conduits. Through these conduits a high tensile steel cable was passed and tensioned. I remember that there were strict rules about where the tank walls could be drilled in relation to the cables and any drilling had to be approved by the manufacturer because of warranty issues.The tanks were above ground construction and about the same cost of traditional RC tanks but so much quicker to erect and commission on fast - track projects.

i think i saw this on discovery network. Its poured with tensioning cable inside it, that can be then screwed down to increase the tensile strength.

# 2 IS RIGHT. THEY PULL' TO 33000 KPS AT 7 DAYS THIS IS CALLED A FLOATING SLAB THAT WILL BEND BUT NOT CRACK LIKE REBAR SLABS CUZ THE CABLES KEEP EVERTHING PULLED TOGETHER. MOSTLY USED IN HEAVY CLAY SOIL. SOME LOVE 'EM SOME HATE'EM, CHEAPER THAN CONVENTIONAL STEEL RE-BAR.
