hollow core pre tensioned garage slabs
(OP)
I ahve a garage in need of restoration - hollow cores show hairline cracking perp. to the strand/core dimesions and in one case the bottom of the slab has delaminated, exposing the strands - what is the best in-situ repair?

Delaminated or totally spalled bottoms with strands hanging down. Not sure what was holding up the floor other than grace from above.
The ultimate solution was to install new rebar in the cores, near the bottom, form up the bottom, and fill the cores with concrete/grout to create a mild-reinforced concrete slab. Another solution would be to pair up that with additional steel framing below the HC to cut down the spans.
