Full title and description

Testing of concrete — Part 13: Properties of fresh self compacting concrete. This International Standard specifies procedures and test methods for assessing the fresh-state properties of self‑compacting concrete, including consistency (slump flow), flow time (V‑funnel), passing ability (L‑box), segregation resistance (sieve segregation), J‑ring and other self‑compactability characteristics.

Abstract

This document provides standardized laboratory methods for evaluating the performance of fresh self‑compacting concrete. It defines test setups, specimen preparation, measurement procedures and reporting requirements for slump flow, V‑funnel, L‑box, sieve segregation, J‑ring and a self‑compactability test, enabling consistent comparison of mixtures and verification of production quality.

Scope

This part of ISO 1920 specifies procedures for testing fresh self‑compacting concrete. The standard covers the following test methods: determination of consistence by slump flow test, V‑funnel test (flow time), L‑box test (passing ability), sieve segregation test (segregation resistance), J‑ring test and a self‑compactability test, together with requirements for apparatus, test execution and reporting. It is intended for use in laboratory and site assessment of mixture behaviour rather than as a full specification of acceptance limits (which are application‑dependent).

Key topics and requirements

• Slump flow test for determination of flowability and spread diameter.
• V‑funnel test to measure flow time and viscosity-related behavior.
• L‑box test to assess passing ability through reinforcements or narrow openings.
• Sieve segregation test to evaluate resistance to segregation of coarse aggregate.
• J‑ring test as an alternative measure of passing ability and flow interruption.
• Definitions of required apparatus dimensions, specimen handling and environmental considerations.
• Details on test repeatability, measurement reporting and recommended test conditions.

These topics reflect the main test methods and procedural requirements defined in the standard.

Typical use and users

Primary users include concrete testing laboratories, materials engineers, mix designers, contractors, precast and ready‑mix producers, research organizations and conformity assessment bodies. Typical uses are mixture development, quality control during production, comparative testing between mixes, and supporting specification or performance assessment of self‑compacting concrete in structures and precast elements.

Related standards

ISO 1920‑13 is part of the ISO 1920 series (Testing of concrete). Related documents commonly referenced include ISO 1920‑1 (sampling of fresh concrete), ISO 1920‑2 (properties of fresh concrete), ISO 3310‑2 (test sieves of perforated metal plate) and other parts of ISO 1920 that cover preparation, curing and tests for hardened concrete. National adoptions and similar regional standards addressing self‑compacting concrete test methods are also used alongside this part.
