What compressive strength of concrete do they use?

Noticed what looks like a control joint or tooled joint, is that required?

Curious.

A hydraulic ram is used to stress the cables and steel wedges (grippers) are inserted at the end to secure them.

Minimum psi for prestressed concrete is 3000.

Joints are added at the discretion of the engineer. Due to the compressive nature of the tendons, large slabs can be poured without the need for any control joints.

Thanks Jeff, and Merry Christmas

Thats what I was going to suggest. Ask Jeff he is an expert in the PT field.. He has helped me before.

I have yet to see a stamp in my neck of the woods. If it was there and I didn't see it I know my buyers would and ask about it. Do any of the other TX inspectors see them?
