Concrete Freezer Floor Design

Concrete freezer floor design.

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. As this surface does not generally affect the overall heat load this design guide assumes a 4 10 cm layer of concrete. Concrete curing in freezers is a unique experience.

An atypical concrete job. Kwik bond will set up and cure without the need to raise surface temperatures use propane torches or heating lamps to accelerate the cure. This concrete is also required to be strong enough to support heavy equipment traffic from forklifts and other machinery. 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.

Type and thickness of insulation this design guide is based on industry standards with a thermal conductivity of. When you think of exterior conditions you think of freezing temperatures. The pink and black coloring on the concrete is microbial growth due to constant and heavy condensation. 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.

Most residential projects only specify minimum concrete. In this case the minimal insulation in the freezer floor became saturated with water from floor washing operations further reducing its. 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.

Typically air entraining admixtures are added to exterior concrete to increase the concrete s durability. Finished floor in freezer applications this surface is typi cally concrete.
