Testing for a horizontal cold joint in a ground floor slab pour?
(OP)
How would go about testing to see if a horizontal cold joint formed in a ground floor slab pour? You suspect a cold joint formed because a portion of the slab was poured in two horizontal layers and the time elapsed between pours was questionable.
I assume you would start with taking some cores. But what would tests would you perform if the cold joint is inconclusive from visual inspection of the cores?

I see. But couldn't there be a situation where there is a gray area (no pun intended)?

Chain dragging is effective for delamination, but has the same limitation as the ultrasonic.
