Standard Specification for Coal Fly Ash and Raw or Calcined Natural Pozzolan for Use in Concrete
Abstract: This specification covers coal fly ash and raw or calcined natural pozzolan for use in concrete where cementitious or pozzolanic action, or both, is desired or where other properties normally attributed to finely divided ... -
Standard Practice for Reducing Samples of Asphalt Mixtures to Testing Size
Abstract: This standard practice outlines methods for the reduction of large samples of asphalt mixture to the appropriate size for testing, employing techniques that are intended to minimize variations in the measured characteristics ... -
Standard Method of Test for Potential Alkali Reactivity of Aggregates and Effectiveness of ASR Mitigation Measures (Miniature Concrete Prism Test, MCPT)
Abstract: This test method allows detection of the potential for deleterious alkali–silica reaction of aggregate in miniature concrete prisms within 56 days (8 weeks) for most of the aggregates. An additional 28 days (4 weeks) may ... -
Standard Specification for Processing Additions for Use in the Manufacture of Hydraulic Cements
Abstract: This specification pertains to the criteria and tests to be used for determining whether an organic or inorganic processing addition, when used in the recommended amount at the option of the cement producer in the manufacture ... -
Standard Method of Test for Surface Resistivity Indication of Concrete’s Ability to Resist Chloride Ion Penetration

Standard Practice for Making and Curing Concrete Test Specimens in the Laboratory
Abstract: This standard practice covers procedures for making and curing test specimens of concrete in the laboratory under accurate control of materials and test conditions. The values stated in either inch-pound units or SI units ... -
Standard Method of Test for Fineness of Hydraulic Cement by the 45-μm (No. 325) Sieve
Abstract: This test method covers the determination of the fineness of hydraulic cement by means of the 45-μm (No. 325) sieve. The values stated in SI units are to be regarded as the standard. The inch-pound equivalents of SI units ... -
Standard Method of Test for Density (Unit Weight), Yield, and Air Content (Gravimetric) of Concrete
Abstract: This method covers determination of the density (see Note 1) of freshly mixed concrete and gives formulas for calculating the yield, cement content, and the air content of the concrete. Yield is defined as the volume of ... -
Standard Method of Test for Air Content of Freshly Mixed Concrete by the Pressure Method
Abstract: This method covers determination of the air content of freshly mixed concrete from observation of the change in volume of concrete with a change in pressure. This method is intended for use with concretes and mortars made ... -
Standard Method of Test for Density of Hydraulic Cement
Abstract: This method covers determination of the density of hydraulic cement. Its particular usefulness is in connection with the design and control of concrete mixtures. The density of hydraulic cement is defined as the mass of ... -
Standard Method of Test for Moisture–Density Relations of Soils Using a 4.54-kg (10-lb) Rammer and a 457-mm (18-in.) Drop
Abstract: This method of test is intended for determining the relationship between the moisture content and density of soils when compacted in a given mold of a given size with a 4.54-kg (10-lb) rammer dropped from a height of 457 ... -
