Kwik bond is designed for concrete floor repair on frozen surfaces such as freezers coolers and holding boxes.
Concrete freezer floor design.
As this surface does not generally affect the overall heat load this design guide assumes a 4 10 cm layer of concrete.
Thus shouldn t air be added to concrete for a freezer floor slab as well since the concrete will be exposed to freezing temperatures.
Kwik bond will set up and cure without the need to raise surface temperatures use propane torches or heating lamps to accelerate the cure.
It is not a good idea to cool a new freezer store quickly as it s more likely to crack especially around the door a high traffic area.
Typically air entraining admixtures are added to exterior concrete to increase the concrete s durability.
Photo 3 shows the exposed concrete ceiling in a retail store below a supermarket freezer room.
Concrete curing in freezers is a unique experience.
Freezer floors also experience a secondary contraction when cooled to below zero temperatures and it s not unusual to see a 10 to 15mm gap between the concrete floor and the insulated wall panels.
Industrial floor designresidential concrete slabs often have few design requirements to get between the contractor and completion of the job.
If the contractor knows what he or she is doing and knows what the customer wants then the lack of specifications is probably a good thing.
The pink and black coloring on the concrete is microbial growth due to constant and heavy condensation.
Finished floor in freezer applications this surface is typi cally concrete.
When you think of exterior conditions you think of freezing temperatures.
Most residential projects only specify minimum concrete.
Type and thickness of insulation this design guide is based on industry standards with a thermal conductivity of.
The major problem with concrete freezer floors is frost buildup under the floor which will cause the floor to lift or heave often destroying the floor and the walls of the freezer as well.
This concrete is also required to be strong enough to support heavy equipment traffic from forklifts and other machinery.
Moisture from the ground below the box is drawn toward the cold freezes expands and so on.
