ASTM C266-15
(Test Method)Standard Test Method for Time of Setting of Hydraulic-Cement Paste by Gillmore Needles
Standard Test Method for Time of Setting of Hydraulic-Cement Paste by Gillmore Needles
SIGNIFICANCE AND USE
5.1 The purpose of this test method is to establish whether a cement complies with a specification limit on Gillmore time of setting.
SCOPE
1.1 This test method covers the determination of the time of setting of hydraulic-cement paste by means of the Gillmore needles.
1.2 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.
1.3 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 and health 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.2
1.4 The text of this standard references notes and footnotes which provide explanatory material. These notes and footnotes (excluding those in tables and figures) shall not be considered as requirements of the standard.

4. Summary of Test Method
4.1 Sufficient water is added to the cement that is being tested to produce a paste of normal consistency. A specimen is molded
from this paste and is tested for time of setting by means of the Gillmore initial and final needles. The initial time of setting is the
time elapsed between initial contact of cement and water and the time when the Gillmore Initial needle does not leave a complete
circular impression in the paste surface. The final time of setting is the time elapsed between initial contact of cement and water
and the time when the Gillmore Final needle does not leave a complete circular impression in the paste surface.
