Overview

EN 12350-9:2010 specifies the V-funnel test for assessing the viscosity and filling ability of self-compacting concrete (SCC). Part of the EN 12350 series for testing fresh concrete, this European Standard defines the apparatus, sample size, test procedure and reporting requirements for measuring the V-funnel flow time (tv). The test is intended for fresh SCC mixes with a maximum aggregate size up to 22.4 mm.

Key topics and technical requirements

• Purpose: Measure V-funnel flow time to evaluate SCC viscosity and filling ability (ability to flow and fill formwork without vibration).
• Scope limit: Not suitable when maximum aggregate size exceeds 22.4 mm.
• Sample: Minimum sample volume 12 L, obtained according to EN 12350-1 (sampling).
• Apparatus:
  • V-shaped funnel manufactured to the standard’s internal dimensions and tolerances, normally metal with smooth, non-corroding surfaces and a quick-release, watertight hinged or sliding gate.
  • Container to collect flow (≥12 L).
  • Stopwatch capable of 0.1 s resolution.
  • Straight edge for striking off level.
• Procedure highlights:
  • Fill funnel in one operation without agitation; strike level with straight edge.
  • After a delay of (10 ± 2) s, open the gate quickly and measure time tv from gate opening until it is possible to see vertically through the funnel into the container.
  • Measure tv to 0.1 s; report to the nearest 0.5 s.
  • Flow must be continuous; repeat test if a blockage occurs. If blockage happens twice, the concrete is considered to lack required SCC viscosity/passing ability.
• Reporting: Test report must include sample identification, location, date/time, V-funnel flow time, any deviations, and a declaration of conformity with the standard. Optional: concrete temperature and age.
• Performance data: The standard supplies repeatability (r) and reproducibility (R) figures derived from multi-laboratory trials for typical tv values.

Applications and users

• Useful for concrete laboratories, quality control (QC) teams, precast plants, contractors and specifiers wanting to:
  • Verify SCC mix design and consistency before casting.
  • Control on-site SCC delivery and placement properties.
  • Compare SCC formulations for filling ability and resistance to segregation.
• Relevant for research institutions and manufacturers developing admixtures or SCC constituents.
