ASTM C1078-87(1992)e1 PDF

Scope: 1.1 These test methods cover two procedures for determining the cement content of a sample of freshly mixed concrete. These methods are applicable to all freshly mixed portland-cement concrete batches for which calibration can be obtained in advance, except those containing certain aggregates or admixtures, that, when washed over a 150~pm (No. 100) sieve, yield significant and varying amounts of calcium ions in solution under the conditions of the test. The choice of which procedure to use is at the discretion of the user. The environment in which these test methods are used may have some bearing on the choice. 1.2 The values stated in inch-pound units are to be regarded as the standard except in regard to sieve sizes which are in accordance with Specification E 11. 1.3 This standard does not purport to address all of the safety problems, 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.
