Overview
EN 12350-8:2019 is a European standard developed by CEN that specifies the testing procedure for assessing the flowability of fresh self-compacting concrete (SCC) using the slump-flow test. The standard focuses on measuring two key parameters: the slump-flow diameter and the t500 time, which reflects the speed at which concrete spreads to a 500 mm diameter after lifting a slump cone. The test is applicable to concrete mixes with coarse aggregates having a maximum size (Dmax) of up to 40 mm.
This test method is essential for evaluating the fresh properties of SCC to ensure it achieves the desired filling ability, homogeneity, and self-compaction without vibration. It supports quality control on-site, especially during the use of new concrete compositions or constituents.
Key Topics
Scope and Applicability
- Testing fresh self-compacting concrete for slump-flow and t500 time
- Suitable for mixes with Dmax ≤ 40 mm
Test Principle
- Concrete is poured into a hollow cone as per EN 12350-2 (slump test)
- Cone is lifted vertically in 1–3 seconds, allowing concrete to flow freely
- Time taken for concrete flow to reach 500 mm diameter (t500 time) is recorded
- Maximum and perpendicular diameters of the spread are measured to calculate slump-flow
Test Apparatus
- Hollow cone, baseplate with marked circles at 210 mm and 500 mm diameters
- Measuring tape, timer, spirit level, remixing container, and optional weighted collar
- Baseplate must be flat, smooth steel or equivalent material for reliable results
Test Procedure
- Ensure horizontal placement of baseplate and dampen cone before filling
- Fill cone in one lift without mechanical compaction; strike off excess
- Remove cone and start timing the flow to the 500 mm mark
- Measure diameters after flow stabilizes, evaluate for segregation
Reporting Results
- Slump-flow (mean diameter) to nearest 10 mm
- t500 time to nearest 0.5 seconds (if measured)
- Qualitative assessment of segregation
- Include test conditions, concrete identification, and any deviations from the standard
Accuracy and Repeatability
- Repeatability and reproducibility values provided based on multi-laboratory studies
- Ensures reliability and consistency in test outcomes across different operators and labs
Applications
Quality Control in Concrete Production
EN 12350-8:2019 provides an efficient and standardized method for concrete producers and site engineers to assess fresh SCC properties, ensuring the concrete mix meets the required flowability for self-compacting behavior.Pre-Construction Testing
Lab testing of new SCC formulations for flow properties before large-scale pouring helps to verify consistency, preventing defects related to poor filling or aggregate segregation.On-Site Verification
The slump-flow test is a practical tool for routine testing on construction sites to monitor SCC workability during placement, especially in complex molds or highly reinforced structures where vibration is impractical.Research and Development
The standard serves as a baseline method for evaluating innovative SCC mixes and admixtures affecting flowability and viscosity.

This document (EN 12350-8:2019) has been prepared by Technical Committee CEN/TC 104 “Concrete
and related products”, the secretariat of which is held by SN.
This European Standard shall be given the status of a national standard, either by publication of an
identical text or by endorsement, at the latest by December 2019, and conflicting national standards
shall be withdrawn at the latest by December 2019.
Attention is drawn to the possibility that some of the elements of this document may be the subject of

This document supersedes EN 12350-8:2010.
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 widely accepted by the construction owners.
The use of SCC in practical concrete construction is steadily 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 fresh SCC are
very important. These should address three key properties: filling ability, passing ability and resistance
to segregation. It is desirable, especially in the case of new constituents or new concrete compositions,
to test the consistence of fresh SCC before casting in place.
A number of test methods including this test are available for testing fresh SCC. Most of the commonly
used test methods were evaluated in the recently closed EU-project “Testing-SCC” under the 5th Frame
Programme (GRD2-2000-30024/G6RD-CT-2001-00580). According to the results from this EU project,
it seems no single test method can completely cover all three key properties. Nevertheless any test
method should at least be correlated to the practical situation and give consistent results in order to
provide reliable data for judgment of concrete workability.
This standard is one of a series on testing concrete.
