GSO EN 1097-6:2024 骨料机械和物理性能试验 第6部分：颗粒密度和吸水率的测定

This document specifies the reference methods used for type testing and in case of dispute, for the determination of particle density and water absorption of normal weight and lightweight aggregates. Other methods can be used for other purposes, such as factory production control, provided that an appropriate working relationship with the reference method has been established. For convenience, some of these other methods are also described in this document. The reference methods for normal weight aggregates are: - a wire basket method for aggregate particles retained on the 31,5 mm sieve (Clause 7, except for railway ballast which uses Annex B); - a pyknometer method for aggregate particles passing the 31,5 mm sieve and retained on the 4 mm sieve (Clause 8); - a pyknometer method for aggregate particles passing the 4 mm sieve and retained on the 0,063 mm sieve (Clause 9). In Clauses 7, 8 and 9, three different particle densities (oven-dried particle density, saturated and surface-dried particle density and apparent particle density) and water absorption are determined after a soaking period of 24 h. In Annex B, the oven-dried particle density is determined after soaking in water to constant mass. For aggregate particles passing the 31,5 mm sieve and retained on the 4 mm sieve, the wire basket method in Clause 7 can be used as an alternative to the pyknometer method in Clause 8. NOTE 1 The wire basket method can also be used for single aggregate particles retained on the 63 mm sieve. NOTE 2 The pyknometer method described in Clause 8 can be used as an alternative for aggregates passing the 4 mm sieve and retained on the 2 mm sieve. The reference methods for lightweight aggregates are: - a pyknometer method for aggregate particles passing the 31,5 mm sieve and retained on the 4 mm sieve (Annex C). Three different particle densities (oven-dried; saturated and surface-dried; apparent) and water absorption are determined after pre-drying and a soaking period of 24 h; - a method, using a Büchner funnel, for aggregate particles passing the 4 mm sieve (Annex D). The three particle densities and water absorption are determined using a vacuum in the range of 50 mbar to 100 mbar for at least five minutes. Three other methods for normal weight aggregates can be used to determine the pre-dried particle density, as specified in normative Annexes A and H: - a wire basket method for aggregate particles passing the 63 mm sieve and retained on the 31,5 mm sieve (A.3); - a pyknometer method for aggregate particles passing the 31,5 mm sieve and retained on the 0,063 mm sieve (A.4); - a pyknometer method for aggregate particles passing the 31,5 mm sieve, including the 0/0,063 mm size fraction (Annex H). NOTE 3 If water absorption is less than about 1,5 %, the apparent particle density can be assessed using the pre-dried particle density method as defined in Annex A. The quick method in normative Annex E can be used in factory production control to determine the apparent particle density of lightweight aggregates. The method in informative Annex F can be used to determine the particle density and water absorption of aggregate particles passing the 4 mm sieve. Data on the density of water at various temperatures is specified in normative Annex G. Guidance on the significance and use of the various density and water absorption parameters is given in informative Annex I. Precision data are presented in informative Annex J.

GSO EN 1097-2:2024 骨料机械和物理性能试验 第2部分：抗碎裂性的测定方法

This document describes the reference method, the Los Angeles test, used for type testing and in case of dispute (and an alternative method, the impact test) for determining the resistance to fragmentation of coarse aggregates (main text) and aggregates for railway ballast (Annex A). For other purposes, in particular factory production control, other methods are possible provided that an appropriate working relationship with the reference method has been established. This document applies to natural, manufactured or recycled aggregates used in building and civil engineering. Annex A describes a method for the determination of resistance to fragmentation of aggregates for railway ballast. Annex B gives alternative narrow range classifications for the Los Angeles test and the impact test. Annex C contains construction, operation and safety requirements for the impact tester. Annex D describes a method for checking of the impact tester. Annex E gives precision data. Annex F contains a worked example of calculation of impact value SZ. Annex G gives an alternative narrow range classification for the Los Angeles test of 16/32 mm recycled aggregates. Annex H proposes an additional sieve for the evaluation of the Los Angeles test for railway ballast. Annex A is normative and Annexes B to H are informative.

GSO EN 933-11:2024 骨料几何特性试验 第11部分：粗再生骨料成分分类试验

This European Standard describes a simple method for the examination of coarse recycled aggregates for the purpose of identifying and estimating the relative proportions of constituent materials. This reference test method should be used for type testing and in case of dispute. For other purposes, in particular factory production control, other methods may be used provided that an appropriate working relationship with the reference method has been established. NOTE 1 This method is not appropriate for lightweight aggregates covered by EN 13055 series. NOTE 2 If dangerous substances are found in while carrying out this method, they should be dealt with in accordance with regulations in the place of use.

This standard describes the reference method used for type testing in cases of dispute, for the determination of the shape index of coarse aggregates. For other purposes, in particular factory production control, other methods may be used provided an appropriate working relationship with the reference method has been established. The test method specified in this European Standard is applicable to particle size fractions di/Di where Di ≤ 63 mm and di ≥ 4 mm.

1.1  This test method covers the sampling, preparation of specimens, and determination of the compressive strength of dimension stone. 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 are not necessarily exact equivalents; therefore, to ensure conformance with the standard, each system shall be used independently of the other, and values from the two systems shall not be combined. 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use. 1.4  This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
