1.1 This test method covers the determination of bulk density ("unit weight") of aggregate in a compacted or loose condition, and calculated voids between particles in fine, coarse, or mixed aggregates based on the same determination. This test method is applicable to...
1.1 This specification covers lightweight aggregate intended to provide water for internal curing of concrete. It includes test methods for determining the absorption and desorption properties of lightweight aggregate. Note 1: Internal curing provides an additional source of water to...
This specification covers fluidifier for grout used for preplaced-aggregate (PA) concrete. Grout ingredients shall conform to the specified requirements for Portland cement, pozzolan, and fine aggregate composition. The fluidifier, tested in grout shall conform to the specified values...
This specification covers ground calcium carbonate (GCC, a type of ground limestone) and other finely divided aggregate mineral filler (AMF) materials for use in concrete mixtures. It defines the types of GCC and AMF materials for use in concrete. If concrete in service is subject to sulfate...
1.1 This test method covers the determination of moisture in mineral aggregate for use on built-up roofs. 1.2 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 be exact equivalents; therefore, each...
4.1 This test method measures the resistance to physical breakdown in handling of built-up roofing aggregates.
1.1 This test method covers the approximate determination of clay lumps and friable particles in aggregates. 1.2 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 be exact equivalents; therefore, each...
1.1 These test methods cover the determination of the loose, uncompacted void content of a sample of fine aggregate. When measured on any aggregate of a known grading, void content provides an indication of that aggregate's angularity, sphericity, and surface texture compared with...
1.1 This test method covers the determination of the effect on mortar strength of the organic impurities in fine aggregate, whose presence is indicated using Test Method C40/C40M. Comparison is made between compressive strengths of mortar made with washed and unwashed fine aggregate....
1.1 This test method covers a procedure for determination of the particle size distribution of fine and coarse aggregates extracted from asphalt mixtures using sieves with square openings. 1.2 The values stated in SI units are to be regarded as standard. No other units of measurement are...
This specification defines the requirements for grading and quality of fine and coarse aggregate for use in concrete. Fine aggregate shall consist of natural sand, manufactured sand, or a combination thereof. Fine aggregate shall be free of injurious amounts of organic...
5.1 This test method provides a procedure to determine the passing ability of self-consolidating concrete. This test method is applicable for laboratory use in comparing the passing ability of different concrete mixtures. It is also applicable in the field as a quality control test. 5.2 The...
5.1 This test method is applicable to the measurement of airborne carbon nanotubes in a wide range of ambient air situations and for evaluation of any atmosphere for carbon nanotube structures. Single carbon nanotube structures in ambient atmospheres have diameters below the resolution limit of the...
1.1 This test method covers the procedure for determining the water retentivity of freshly mixed hydraulic cement grout mixtures for preplaced-aggregate (PA) concrete. 1.2 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this...
5.1 The Micro-Deval abrasion test is a test of fine aggregate to determine abrasion loss in the presence of water and an abrasive charge. Many aggregates are more susceptible to abrasion when wet than dry, and the use of water in this test incorporates this reduction in resistance to...
4.1 This test method provides a means for evaluating the ability of pozzolans and slag cement to control deleterious internal expansion due to alkali-silica reaction when used with an aggregate intended for use in concrete. It is based on the Accelerated Test Method developed at the National...
5.1 This test method is applicable to the measurement of airborne asbestos in a wide range of ambient air situations and for detailed evaluation of any atmosphere for asbestos structures. Most fibers in ambient atmospheres are not asbestos, and therefore, there is a requirement for fibers to be...
1.1 This test method describes the procedures for measuring in-place density and moisture of soil and soil-aggregate by use of nuclear equipment (hereafter referred to as "gauge"). The density of the material may be measured by direct transmission, backscatter, or backscatter/air-gap ratio...
1.1 This performance specification covers hydraulic cements for both general and special applications. There are no restrictions on the composition of the cement or its constituents (see Note 1). Note 1: There are two related hydraulic cement standards, Specification C150/C150M for portland cement...
1.1 This test method covers the quantitative determination of the rate of moisture vapor emitted from below-grade, on-grade, and above-grade (suspended) bare concrete floors. 1.2 This test shall not be used to evaluate the rate of moisture vapor emitted by gypsum concrete or floors containing...
