SFRC vs Traditional Rebar: Cost Comparison

Detailed cost comparison showing how SFRC reduces total project costs by 15-30% for industrial floor applications.

When comparing SFRC to traditional rebar mesh for slab-on-grade applications, the total installed cost — not just material cost — is what matters. While steel fibers may have a higher material cost per tonne than rebar, the labor and time savings typically result in 15-30% lower total project costs. Material costs: A typical warehouse floor using SFRC at 30 kg/m³ dosage might cost $15-20/m² for the fiber material. An equivalent rebar mesh design might cost $10-15/m² for the steel, but requires additional items: spacer bars, chairs, tie wire, and lap lengths. Labor costs: This is where SFRC wins decisively. Rebar mesh requires cutting, bending, placing on chairs, tying intersections, and lapping — all labor-intensive operations that are prone to error. SFRC fibers are simply added to the concrete mixer. A typical 1,000 m² floor pour might require 8-10 workers for rebar placement over 2 days, versus zero additional workers for SFRC. Construction time: SFRC pours are 30-50% faster because there is no reinforcement fixing phase. This translates to earlier project completion and reduced preliminary costs (site supervision, crane hire, temporary works). Quality: Rebar mesh frequently suffers from placement errors — mesh sitting on the subgrade instead of being properly supported on chairs, incorrect cover depths, and missing lap lengths. These defects compromise the floor's structural performance. SFRC eliminates all placement-related quality issues because the fibers are integral to the concrete. When all costs are combined — material, labor, equipment, time, and quality-related rework — SFRC typically saves 15-30% on total floor construction costs for industrial applications.
