(Test Method)Standard Test Method for Time of Setting of Hydraulic Cement Mortar by Modified Vicat Needle
Standard Test Method for Time of Setting of Hydraulic Cement Mortar by Modified Vicat Needle
SIGNIFICANCE AND USE
The purpose of this test method is to establish whether or not a cement complies with a specification limit on time of setting. It has been found to be particularly applicable for the determination of the setting time of expansive cements (see Specification C 845).
SCOPE
1.1 This test method covers the determination of the time of setting of hydraulic cement mortar by means of the modified Vicat needle.
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. The use of gloves, protective clothing, and eye protection is recommended. Wash contact area with copious amounts of water after contact. Wash eyes for a minimum of 15 min. Avoid exposure of the body to clothing saturated with the liquid phase of the unhardened material. Remove contaminated clothing immediately after exposure.)
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 A mortar is prepared with the cement to be tested, using stipulated quantities of cement and water, and sufficient standard
sand to produce a required consistency as determined by a stipulated penetration using the plunger of the modifiedVicat apparatus.
Mortar of the proper consistency is then tested for time of setting, using the needle of the modified Vicat apparatus for the
determination of a stipulated penetration. The time required to obtain the stipulated penetration of the modified Vicat needle is the
time of setting.
