Significance and Use
4.1 The sampling procedures described are intended for use in the procurement of samples of hydraulic cement after it has been manufactured and is ready to be offered for sale. They are not intended as sampling procedures for quality control purposes during manufacturing. The testing procedures outlined cover the amount of testing to be done and provide guidance for reporting on conformance or non-conformance of cements with requirements of purchase specifications.
4.2 This practice is referenced as the procedure for sampling masonry cement (Specification C91), portland cement (Specification C150), blended hydraulic cement (Specification C595), expansive hydraulic cement (Specification C845), plastic stucco cement (Specification C1328), mortar cement (Specification C1329), and hydraulic cement based on a performance specification (Specification C1157).
4.3 Most building codes and construction specifications require that hydraulic cement to be used in the work meet the applicable requirements of the relevant purchase specifications, such as Specifications C91, C150, C595, C1157, C1328, C1329, or C845. If the code or specification requires sampling of the manufactured cement, the provisions given in 4.4 are applicable. Not much cement is sold on the basis of such sampling and testing. A useful discussion of sampling and testing cement is contained in ACI 225.1R.
4.4 The procedures covered in this practice should be done by or for purchasers of hydraulic cement who are using a code or specification that requires sampling and testing to determine if the samples conform to the relevant acceptance specifications. The testing is done using specified methods to determine whether the samples yield test results that conform to the specification, and the tests serve as a basis for acceptance or rejection of the lot of material sampled.
4.5 It is neither intended nor required that all cements be tested using all the test methods referenced in Section 2.
1.1 This practice covers procedures for sampling and for the amount of testing of hydraulic cement after it has been manufactured and is ready to be offered for sale.
1.2 The values stated in SI units are to be regarded as the standard. The inch-pound units in parentheses are for information purposes only.
1.2.1 A ton as used in this practice is 907 kg (2000 lb).
1.2.2 Values in SI units shall be obtained by measurement in SI units or by appropriate conversion, using the Rules for Conversion and Rounding given in Standard IEEE/ASTM SI 10, of measurement made in other units.
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.
