January 1, 2020 - AASHTO

These test methods determine the time of setting of hydraulic cement by means of the Vicat needle. Two test methods are given: Method A is the Reference Test Method using the manually operated standard Vicat apparatus, while Method B permits the use of an automatic Vicat machine that has, in...

AASHTO T 186 - Standard Method of Test for Early Stiffening of Hydraulic Cement (Paste Method)

January 1, 2020 - AASHTO

This test method covers the determination of early stiffening in hydraulic cement paste. The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only. This standard does not purport to address all the safety concerns, if any, associated...

AASHTO T 11 - Standard Method of Test for Materials Finer Than 75-μm (No. 200) Sieve in Mineral Aggregates by Washing

January 1, 2020 - AASHTO

This test method covers determination of the amount of material finer than a 75-μm (No. 200) sieve in aggregate by washing. Clay particles and other aggregate particles that are dispersed by the wash water, as well as water-soluble materials, will be removed from the aggregate during the test. Two...

AASHTO T 153 - Standard Method of Test for Fineness of Hydraulic Cement by Air Permeability Apparatus

January 1, 2020 - AASHTO

This test method covers determination of the fineness of hydraulic cement, using the Blaine air permeability apparatus, in terms of the specific surface expressed as total surface area in square centimeters per gram or square meters per kilogram of cement. Two test methods are given: Test Method A...

AASHTO T 140 - Standard Method of Test for Compressive Strength of Concrete Using Portions of Beams Broken in Flexure

January 1, 2020 - AASHTO

This method covers the determination of compressive strength of concrete, using portions of beams broken in flexure for test specimens. Note 1-This method was originally developed to cover testing portions of beams having a square cross section as "modified cubes" and former versions of this...

AASHTO T 180 - 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

January 1, 2020 - AASHTO

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 mm (18 in.). Four alternate procedures are provided as follows: • Method A-A...

AASHTO T 133 - Standard Method of Test for Density of Hydraulic Cement

January 1, 2019 - AASHTO

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 a unit volume of the solids. The values stated in SI units are to be regarded...

AASHTO T 121M/T 121 - Standard Method of Test for Density (Unit Weight), Yield, and Air Content (Gravimetric) of Concrete

January 1, 2019 - AASHTO

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 concrete produced from a mixture of known quantities of the component materials...

AASHTO T 152 - Standard Method of Test for Air Content of Freshly Mixed Concrete by the Pressure Method

January 1, 2019 - AASHTO

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 with relatively dense aggregates for which the aggregate correction factor...

AASHTO T 192 - Standard Method of Test for Fineness of Hydraulic Cement by the 45-μm (No. 325) Sieve

January 1, 2019 - AASHTO

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 may be approximate. This standard does not purport to address all of the...

AASHTO T 134 - Standard Method of Test for Moisture–Density Relations of Soil–Cement Mixtures

January 1, 2019 - AASHTO

These methods of test are intended for determining the relation between moisture content and density of soil-cement mixtures when compacted before cement hydration as prescribed. A 944-cm3 (1/30-ft3) mold and a 2.5-kg (5.5-lb) rammer dropped from a height of 305 mm (12 in.) are used and two...

TAPPI T 1211 - Self-certification practice for organizations providing reference materials for TAPPI Standards

January 1, 2019 - TAPPI

This standard practice establishes the "self certification" procedures for an organization to nominate itself, and be accepted, as a TAPPI calibration laboratory for inclusion in the Reference Material List within the published TAPPI Standards. Organizations that have national or international...

AASHTO T 106M/T 106 - Standard Method of Test for Compressive Strength of Hydraulic Cement Mortar (Using 50-mm or 2-in. Cube Specimens)

January 1, 2018 - AASHTO

This test method covers determination of the compressive strength of hydraulic cement mortar using 50-mm (or 2-in.) cube specimens (see Note 1).
