Design of Industrial Flooring

What causes the deterioration must be taken into account:

and its intended used:

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. Keep reading the instruction on cleaning of Industrial floor.
