Design of Industrial Flooring

Industrial Floor DesignSelection and Design of the Industrial Flooring

What causes the deterioration must be taken into account:

  • Mechanical: Abrasion/ Erosion/ Impact/ Vibration
  • Physical: Temperature/Humidity/ Water/Frost
  • Chemical and Biological: Acids/ Oil/  Grease/ Gas/ Micro-organisms

and its intended used:

  • Design: Assessment/ Standards/ Calculation/ Measurement/ Details
  • Materials: Composition/ Properties/ Quality/ Durability/ Maintenance
  • Labour: Experience/ Care/ Quality Control/ Concern

Factors to take into account for the design and construction of industrial flooring

  • Ground conditions: strength, water table, type of soil, sub grade
  • Type of slab: ground supported or pile supported or suspended slab
  • Traffic and other loading requirements: frequency, duty and free or define traffic
  • Method of construction: in stages/bays, in strips or in large pour
  • Concrete mix design (especially critical w/c ratio):
    • The concrete deliveries must be of consistent quality. Otherwise negative impact on wetting/dry-shake workability/final finish performance (abrasion) and appearance.
    • A concrete slump in the range 75 to 110mm will normally give best results. This will depend on the placing method (manual/mechanical)
    • Do not use concrete where cement has partly been replaced with fly ash. This makes the mix is too sticky for proper dry-shake placing and workability, and will cause blisters during power-floating. Blisters are also caused by too early floatng or with inadequate tools (steel instead of wood or magnesium)
  • Slab thickness and reinforcement requirements: steel fibers or re-bars, other fiber types and combination
  • Jointless slabs or join spacing and positioning: Pinwheel contraction joint to separate columns. Design of joints according to traffic requirements. Less joints mean less cost (need for slab connectors) and less chance of damage and wear.
  • Surface smoothness and flatness: TR34, ACI 117, DIN 15185, ASTM E 1155
  • Durability and special operational conditions
  • Lighting: Use of lighter colour dryshakes helps reduce cost.

Conclusion

Again, never blame the product first. Failure can be due to the product, but are minimal and are mostly detected at QC:

  • Malfunctions in equipment: Adding too much or too little particular raw material
  • Human error

A proper design ensure the success of industrial flooring.
