Overview
oSIST prEN 12350-9:2008, published by the Slovenian Institute for Standardization (SIST), is a European draft standard under the EN 12350 series. This part of the standard focuses on testing fresh concrete, specifically self-compacting concrete (SCC), using the V-funnel test. The procedure measures the flow time of SCC to assess its viscosity and filling ability, critical parameters for ensuring quality in modern concrete construction projects. Notably, the V-funnel test method applies only when the maximum aggregate size does not exceed 20 mm.
Key Topics
- Self-compacting Concrete (SCC): SCC is a highly flowable type of concrete that spreads into place under its own weight, filling formwork and encapsulating reinforcement without mechanical vibration.
- V-funnel Test Procedure:
- Evaluates the viscosity and flow performance of fresh SCC.
- Involves measuring the time (flow time) for concrete to pass through a standardized V-funnel apparatus.
- Test not appropriate for SCC containing aggregates larger than 20 mm.
- Testing Apparatus:
- V-funnel: Made of metal, designed to resist rust and attack from cement paste.
- Container: Collects discharged concrete.
- Stopwatch: Measures flow time to 0.1 seconds.
- Straight Edge: Used for leveling the top surface of the concrete in the funnel.
- Test Sample Requirements: Minimum sample volume of 12 liters is prepared as specified in EN 12350-1.
- Reporting:
- Includes sample identification, location, date and time, V-funnel flow time, concrete age, procedural deviations, and a responsible declaration.
- Optional: concrete temperature at test time.
Applications
The V-funnel test for self-compacting concrete is widely used across the construction industry for:
- Quality Control: Ensuring SCC batches meet required viscosity and flow characteristics before placement.
- Performance Assessment: Evaluating SCC workability, especially in complex formwork or heavily reinforced sections where full compaction is essential.
- Mix Design Verification: Checking the consistency of new or modified SCC mixes, particularly when using innovative materials or admixtures.
- On-site and Laboratory Testing: Suitable for both field and laboratory environments, aiding rapid decision-making and validation of concrete supplied for construction projects.
- Compliance with Specifications: Supports contractors and engineers in meeting technical requirements for SCC as outlined in public and private building contracts.
The method is applicable to many types of building and civil engineering works where SCC is specified, including high-rise structures, bridges, precast elements, and infrastructure with congested reinforcement.

Foreword
This document (prEN 12350-9:2007) has been prepared by Technical Committee CEN/TC 104 “Concrete and
related products”, the secretariat of which is held by DIN.
This document is currently submitted to the CEN Enquiry.
This standard is based on the results from the EU-project “Testing-SCC” under the 5th Frame Programme
(GRD2-2000-30024/G6RD-CT-2001-00580).
Owing to its significant advantages in the improvement of construction quality and working environment, self-
compacting concrete (SCC) has been more widely accepted by the construction owners. The use of SCC in
practical concrete construction is stably increasing. Since SCC has to give satisfactory in-situ properties
(perfect filling of the mould and embedment of the reinforcement, homogeneity and full compaction) without
vibration, the proper methods for testing the workability of fresh SCC are very important. The workability of
fresh SCC should basically include three key properties: filling ability, passing ability and resistance to
