This method covers the determination of the percentage of lightweight particles in aggregate by means of sink-float separation in a heavy liquid of suitable specific gravity. The values stated in SI units are to be regarded as the standard. This standard involves hazardous materials, operations, or...

This method covers the determination of the degree of particle coating in an asphalt mix on the basis of the percentage of coarse aggregate particles that are completely coated. Determination of the percentage of coated particles for varying mixing times may be used to establish the least mixing...

This test method covers the determination of the time of setting of hydraulic cement paste by means of the Gillmore needles. The values stated in inch-pound units are to be regarded as standard. The SI units, regarded as standard in ASTM C266, are provided for informational use only with regard to...

This test method covers determination of the autoclave expansion of hardened hydraulic cement paste when exposed to the autoclave conditions in this method. The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not...

This test method covers determination of slump of concrete, both in the laboratory and in the field. The values stated in either SI units or inch-pound units are to be regarded separately as standard. Within the text, the inch-pound units are shown in brackets. The values stated in each system are...

This Standard Practice deals only with simplified color indices applicable specifically to white colors. There are approximately 5000 distinguishable white colors. As with any other color, three numbers are necessary for the complete identification of any white. All the color and color difference...

The purpose of this standard is to provide guidelines for skills and knowledge needed by a paper machine tender, often referred to as the paper machine first hand. The standard will be useful as a measure of the capabilities and understanding that a person must have to successfully perform the...

This test is intended to serve as a rapid test to show the relative proportions of fine dust or claylike material in soils or graded aggregates. The following applies to all specified limits in this standard: For the purpose of determining conformance with these specifications, an observed value or...

This method covers the determination of the resistance of concrete specimens to rapidly repeated cycles of freezing and thawing in the laboratory by two different procedures: Procedure A, Rapid Freezing and Thawing in Water, and Procedure B, Rapid Freezing in Air and Thawing in Water. Both...

This method covers the determination of the flexural strength of concrete specimens by the use of a simple beam with center-point loading. It is not an alternative to T 97. The values stated in SI units or inch-pound units are to be regarded separately as standard. The values stated in each system...

This test method covers determination of the length changes that are produced by causes other than externally applied forces and temperature changes in hardened hydraulic-cement mortar and concrete specimens made in the laboratory and exposed to controlled conditions of temperature and moisture....

This method of test covers the determination of bulk specific gravity (Gmb) of specimens of compacted asphalt mixtures. This method should not be used with samples that contain open or interconnecting voids or absorb more than 2.0 percent of water by volume, as determined in Sections 7.2 or 10.2...

This method covers the mechanical mixing of hydraulic cement pastes and mortars of plastic consistency. The values stated in SI units are to be regarded as the standard. This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility...

This practice covers the location from which samples are taken from a sheet of fiber glass mat used as a sample test unit for physical property determination.

This method covers the determination of early stiffening in hydraulic cement mortar. The values stated in SI units are the standard. The values in parentheses are for information only. This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the...

This test method covers the determination of portland cement content of a sample of hardened hydraulic-cement concrete. The values in SI units are to be regarded as the standard. The values given in parentheses are provided for information purposes only. This standard does not purport to address...

This practice defines the preconditioning and test conditions for testing fiber glass mats.

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. The values stated in SI units are to be regarded as the standard. The inch-pound units in parentheses are for information purposes only....

This test method covers determination of the thickness of a concrete pavement, slab, or structural element by measuring the length of a core drilled from a concrete structure. The values stated in SI units are to be regarded as the standard. This standard does not purport to address all of the...
