Any ideas for freezer warehouse slab with heavy forklift traffic?
(OP)
A freezer warehouse was constructed 3 years ago. Specifications for the freezer topping slab were 40MPa concrete, 4-8% entrained air. No hardening agent or surface densifiers were used. Internal concrete slab received hard trowelled finish. High reach forklift truck with hard (non-pneumatic) wheels provides cyclic loading to the slabs. Slabs are exhibiting surface scaling / flaking /delaminations (not yet confirmed by testing) but rectification will be required.
What is likely cause of the surface problems?
Would these problems likely be occurring if the forklifts had pneumatic tyres?
What specification should be recommended for this type of application? Durability needs to consider freezing (although not cyclic freezing / thawing - constantly operating at -23 degrees celcius) and also repetitive forklift traffic with non-pneumatic tyres.
Any advice?

There is a lot of information on this out there in the world about troweling and air-entrainment. Here is an article from a magazine i use to subscribe too. http://www.concreteconstruction.net/Images/Beware%...
