Moisture from the ground below the box is drawn toward the cold freezes expands and so on.
Concrete freezer floor design.
When you think of exterior conditions you think of freezing temperatures.
Thus shouldn t air be added to concrete for a freezer floor slab as well since the concrete will be exposed to freezing temperatures.
Industrial floor designresidential concrete slabs often have few design requirements to get between the contractor and completion of the job.
Kwik bond is designed for concrete floor repair on frozen surfaces such as freezers coolers and holding boxes.
This concrete is also required to be strong enough to support heavy equipment traffic from forklifts and other machinery.
In this case the minimal insulation in the freezer floor became saturated with water from floor washing operations further reducing its.
Walk in freezer concrete floor construction requires a specially cured solution that can handle constant sub freezing temperatures.
The pink and black coloring on the concrete is microbial growth due to constant and heavy condensation.
Kwik bond will set up and cure without the need to raise surface temperatures use propane torches or heating lamps to accelerate the cure.
Photo 3 shows the exposed concrete ceiling in a retail store below a supermarket freezer room.
An atypical concrete job.
Type and thickness of insulation this design guide is based on industry standards with a thermal conductivity of.
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.
Typically air entraining admixtures are added to exterior concrete to increase the concrete s durability.
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.
Concrete curing in freezers is a unique experience.
Most residential projects only specify minimum concrete.
Finished floor in freezer applications this surface is typi cally concrete.
