This test method can be used as a quality-control test for slag production from a single source after adequate correlation with tests stipulated in Specification C989.

This test method may be used as an evaluation technique for slag cement, when an appropriate correlation with various finenesses of slag cements from a specific source ground in a specific laboratory mill has been previously developed.

The hydraulic activity as measured by this test method on slag cement samples can provide guidance to a manufacturer as to fineness level required to maintain a certain level of hydraulic activity.

While this test method is intended primarily as a quality control test, some studies have shown that the test method is capable of evaluating the hydraulic activity of slag cements from different sources.

1. Scope

1.1 This test method covers the rapid determination of hydraulic activity of slag cement. This test method measures the accelerated strength development of the slag cement by using sodium hydroxide solution as mixing water and curing at elevated temperature.

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. A specific warning statement is given in Section 6.

1.4 The text of this standard references notes and footnotes which provide explanatory information. These notes and footnotes (excluding those in tables) shall not be considered as requirements of this standard.

2. Referenced Documents (purchase separately) The documents listed below are referenced within the subject standard but are not provided as part of the standard.
