4.1 The following practices are to be used in obtaining samples that are representative of the lot being sampled. The methodology used will be dependent upon the size and type of material sampled and testing requirements. 4.2 The following practices are intended for use in obtaining samples from material that is ready for sale and are not intended as sampling procedures for quality control purposes. These practices are to be used in obtaining a laboratory sample that will yield results serving as a basis for acceptance or rejection of the lot of material sampled. This does not preclude the use of these practices for quality control purposes. 4.3 The following practices can be used to eliminate bias in sampling. The person or persons responsible for using these practices must be trained and they will be conscientious and timely in their use. 4.4 An agreement between the producer and the consumer on location of sampling, either at the producer's plant or at the destination, is encouraged. Product quality can be affected through careless handling, improper protection, and delayed shipment. It is preferable to sample at the point of loading. The consumer has the right to witness the sampling practices being used. 4.5 This practice may be used to provide a representative sample of lime or limestone products. Due to the variability of limestone and lime and the wide variety of sampling equipment, caution must be exercised in all stages of sampling, from system specification and equipment procurement to equipment acceptance testing and actually taking the final sample. 1.1 This practice covers procedures for the collection and reduction of samples of lime and limestone products to be used for physical and chemical tests. 1.2 This practice further covers inspection, rejection, retesting, packing, and marking of lime and limestone products as it may be used in the chemical, agricultural, and process industries. 1.3 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 may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard. 1.4 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.

ASTM C117-13 用冲洗法测定矿物集料中细于200号筛孔(75μm)的材料的标准试验方法

4.1 Material finer than the 75-μm (No. 200) sieve can be separated from larger particles much more efficiently and completely by wet sieving than through the use of dry sieving. Therefore, when accurate determinations of material finer than 75 μm in fine or coarse aggregate are desired, this test method is used on the sample prior to dry sieving in accordance with Test Method C136. The results of this test method are included in the calculation in Test Method C136, and the total amount of material finer than 75 μm by washing, plus that obtained by dry sieving the same sample, is reported with the results of Test Method C136. Usually, the additional amount of material finer than 75 μm obtained in the dry sieving process is a small amount. If it is large, the efficiency of the washing operation should be checked. It could also be an indication of degradation of the aggregate. 4.2 Plain water is adequate to separate the material finer than 75 μm from the coarser material with most aggregates. In some cases, the finer material is adhering to the larger particles, such as some clay coatings and coatings on aggregates that have been extracted from bituminous mixtures. In these cases, the fine material will be separated more readily with a wetting agent in the water. 1.1 This test method covers the 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. 1.2 Two procedures are included, one using only water for the washing operation, and the other including a wetting agent to assist the loosening of the material finer than the 75-μm (No. 200) sieve from the coarser material. Unless otherwise specified, Procedure A (water only) shall be used. 1.3 The values stated in SI units are to be regarded as the standard. No other units of measurement are included in this standard. 1.4 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.

ASTM C1777-13 细集料或矿物填料亚甲基蓝值快速测定用标准试验方法

5.1 This test method is used to determine rapidly the amount of methylene blue adsorbed by a specimen of fine aggregate or mineral filler. The result is reported as a methylene blue value in units of mg of methylene blue adsorbed per g of fine aggregate or mineral filler. The methylene blue value is a function of the amount and characteristics of clay minerals present in the test specimen. High methylene blue values indicate increased potential for diminished fine aggregate or mineral filler performance in a cementitious mixture due to the presence of clays. Note 1—Results from this test method are not expected to be correlated with those obtained using AASHTO T 330 or EN 933-9. These three test methods are likely to give very different numerical values even though the units are the same. The AASHTO T 330 test is performed only on the fraction of an aggregate passing the 75 μm sieve, the EN 933-9 test is performed only on the fraction finer than 2 mm, and this test is performed on the fraction finer than the 4.75 mm sieve. Therefore, when testing the same fine aggregate source, the AASHTO test method would give the highest methylene blue value because any clay present in the specimen would be concentrated in the fraction finer than the 75 μm sieve. The AASHTO and EN test methods do not take into account the amount of material passing the 75 μm sieve or 2 mm sieve, respectively. For example, a fine aggregate with high methylene blue value measured by the AASHTO method but low percentage passing the 75 μm sieve may have less effect on concrete performance than a fine aggregate with low methylene blue value measured by the AASHTO method but a high percentage passing the 75 μm sieve. In contrast, this test method expresses methylene blue value based on the entire fine aggregate or mineral filler specimen. Additionally, the AASHTO and EN test methods use titration to determine the amount of methylene blue of known concentration that is adsorbed by a specimen and require the operator to visually determine the end point of the test. In contrast, this test method uses a colorimeter to detect the change in concentration of methylene blue solution before and after being mixed with the fine aggregate or mineral filler specimen. Note 2—Recommendations for maximum methylene blue values for specific applications are not provided in this test method. Maximum methylene blue values should be established based on successful performance of fine aggregate or mineral filler in the applications under consideration. 1.1 This test method provides a rapid test to determine the amount of methylene blue adsorbed by a specimen of fine aggregate or mineral filler and can be used both in the laboratory and in the field. 1.2 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard. 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.
