ASTM C1610/C1610M-21

This document is not an ASTM standard and is intended only to provide the user of an ASTM standard an indication of what changes have been made to the previous version. Because
it may not be technically possible to adequately depict all changes accurately, ASTM recommends that users consult prior editions as appropriate. In all cases only the current version
of the standard as published by ASTM is to be considered the official document.
Designation: C1610/C1610M − 19 C1610/C1610M − 21
Standard Test Method for
Static Segregation of Self-Consolidating Concrete Using
Column Technique
This standard is issued under the fixed designation C1610/C1610M; the number immediately following the designation indicates the
year of original adoption or, in the case of revision, the year of last revision. A number in parentheses indicates the year of last
reapproval. A superscript epsilon (´) indicates an editorial change since the last revision or reapproval.
1. Scope*
1.1 This test method covers the determination of static segregation of self-consolidating concrete (SCC) by measuring the coarse
aggregate content in the top and bottom portions of a cylindrical specimen (or column).
1.2 This test method is not applicable to self-consolidating concrete containing lightweight aggregate.
1.3 This test method is applicable under laboratory and field conditions.
1.4 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each
system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the
two systems may result in non-conformance with the standard.
1.5 The text of this standard references notes and footnotes that provide explanatory material. These notes and footnotes
(excluding those in tables and figures) shall not be considered as requirements of the standard.
1.6 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility
of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of
regulatory limitations prior to use. (Warning—Fresh hydraulic cementitious mixtures are caustic and may cause chemical burns
to skin and tissue upon prolonged exposure. )
1.7 This international standard was developed in accordance with internationally recognized principles on standardization
established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued
by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

3. Terminology
3.1 Definitions:
3.1.1 For definitions of terms used in this test method, refer to Terminology C125.
3.2 Definitions of Terms Specific to This Standard:
3.2.1 static segregation, n—settlement of coarse aggregate particles in an undisturbed mass of fresh concrete.
4. Summary of Test Method
4.1 A sample of freshly-mixed self-consolidating concrete is placed in a cylindrical mold without tamping or vibration. The mold
is separated into three sections representing different levels of the cylindrical specimen (or column). Portions of SCC from the top
and bottom section are washed on a 4.75 mm (No. 4) sieve, leaving the coarse aggregate on the sieve. The masses of coarse
aggregate in the top and the bottom sections are determined and the percent static segregation is calculated.
5. Significance and Use
5.1 This test method provides users with a procedure to determine the potential static segregation of self-consolidating concrete.
NOTE 1—This test method may not be sufficiently rapid to evaluate self-consolidating concrete mixtures in the field before placement. Test Method C1712
provides a rapid method for assessing static segregation resistance of self-consolidating concrete.
5.2 This test method shall be used to develop self-consolidating concrete mixtures with segregation not exceeding specified limits.
Self-consolidating concrete is a fluid concrete that can be prone to segregation if not proportioned to be cohesive. A cohesive
self-consolidating concrete is important for all applications but is especially critical for deep-section applications such as walls or
columns. Therefore, the degree of segregation can indicate if a mixture is suitable for the application.
NOTE 2—Some level of segregation is tolerable as long as the desired strength and durability performance is achieved.
6. Apparatus
6.1 Balance—as described in Test Method C127.
6.2 Column Mold—The column portion of the mold shall be poly(vinyl chloride) (PVC) plastic pipe Schedule 40 meeting the
requirements of Specification D1785. The column shall be 200 mm [8 in.] in nominal diameter by 660 mm [26 in.] in height and
separated into 3 sections. The top section shall be 165 mm [6.5 in.] in height, the middle section 330 mm [13 in.] in height, and
the bottom section 165 mm [6.5 in.] in height, as shown in Fig. 1. Each section shall have its ends flat and plane and be marked
as “Top”, “ Middle”, or “Bottom” relative to its location in the column. Couplers, brackets, clamps, or other equivalent fastening
systems shall be used for securing the column sections together to form a mortar-tight joint and to secure the column to the base
plate. The column mold shall be securely attached to a non-absorbent, rigid base plate measuring at least 300 mm [12 in.] by 300
mm [12 in.] square.
NOTE 3—Experience has shown that a base plate made from sealed or
