What is the reason for bull floating a newly placed concrete slab?

• A. Embed large aggregates, fill holes, and level the concrete surface
• B. Consolidate / bond fresh concrete
• C. Eliminate the need for screeding
• D. Remove excess bleed water from the surface

Answer: (A)

Bull floating is the finishing step used to smooth the surface by embedding protruding aggregates, filling small holes and voids, and bringing the cream (cement paste) to the surface to level the top. This creates a uniform, workable surface that’s ready for final finishing. It’s not about consolidating fresh concrete (that’s the job of vibrators) and it doesn’t purposefully remove bleed water—the surface should be finished after any excess water has dissipated. So the reason matches the function: embedding large aggregates, filling holes, and leveling the surface for a good final finish.
