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.
Concrete freezer floor design.
The pink and black coloring on the concrete is microbial growth due to constant and heavy condensation.
Concrete curing in freezers is a unique experience.
Thus shouldn t air be added to concrete for a freezer floor slab as well since the concrete will be exposed to freezing temperatures.
Most residential projects only specify minimum concrete.
Kwik bond is designed for concrete floor repair on frozen surfaces such as freezers coolers and holding boxes.
As this surface does not generally affect the overall heat load this design guide assumes a 4 10 cm layer of concrete.
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.
In this case the minimal insulation in the freezer floor became saturated with water from floor washing operations further reducing its.
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.
Photo 3 shows the exposed concrete ceiling in a retail store below a supermarket freezer room.
Typically air entraining admixtures are added to exterior concrete to increase the concrete s durability.
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.
Kwik bond will set up and cure without the need to raise surface temperatures use propane torches or heating lamps to accelerate the cure.
An atypical concrete job.
When you think of exterior conditions you think of freezing temperatures.
Industrial floor designresidential concrete slabs often have few design requirements to get between the contractor and completion of the job.
Moisture from the ground below the box is drawn toward the cold freezes expands and so on.
Walk in freezer concrete floor construction requires a specially cured solution that can handle constant sub freezing temperatures.
