You might find your information on this website. It's a little hard to navigate so if you get lost go to "Site" and restart. We used these people a lot and were quite satisfied with the service.
This site gives information on repairing. You will have to determine what type of core etc. you have. Acceptable guidelines would depend on industry you are in but ASTM has a lot of information on design and testing.
which has an excellent collection of information from the International Concrete Repair Institute and the American Concrete Institute. Unfortunately my current employer doesn’t subscribe so I can’t forward you any info from that site.
Sika has some good concrete repair products. They say that their high build repair mortar MonoTop-615HB can be used to repair honeycombing and voids caused by faulty formwork.
Lutfi:
Is the honeycomb damage of a structural nature or is it appearance? How extensive is it?
Repair is a matter of removing the loose honeycombed material and replacing it with a bonded patch. If appearance is not an issue, then the repair is easy, but ugly!
If appearance is an issue, then the problem is difficult... it is nearly impossible to repair a patch in a satisfactory manner. There are outfits like Nawcaw that can repair surfaces to look like the original.
