ASTM C1621/C1621M-17 利用J环测定自密实混凝土通过能力的标准试验方法

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 difference between the slump flow and J-Ring flow is an indication of the passing ability of the concrete. A difference less than 25 mm [1 in.] indicates good passing ability and a difference greater than 50 mm [2 in.] indicates poor passing ability. The orientation of the mold for the J-Ring test and for the slump flow test without the J-Ring shall be the same. 5.3 This test method is limited to self-consolidating concrete with nominal maximum size of aggregate of up to 25 mm [1 in.]. 1.1 This test method covers determination of the passing ability of self-consolidating concrete (SCC) by using the J-Ring in combination with a mold. 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 system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard. 1.3 The text of this standard references notes and footnotes that provide explanatory material. These notes and footnotes (excluding those in tables and figures) shall not be considered as requirements of 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. (Warning—Fresh hydraulic cementitious mixtures are caustic and may cause chemical burns to skin and tissue upon prolonged exposure.2) 1.5 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.

ASTM C1623-17a 混凝土砌体过梁制成品的标准规格

1.1 This specification covers concrete masonry lintels (beams) that are solid in cross-section, are reinforced for flexure, and are made from hydraulic cement, water, and mineral aggregates with or without the inclusion of other materials. These lintels are suitable for both loadbearing and nonloadbearing applications. Note 1: This specification covers only concrete masonry lintels containing reinforcement. Due to building code imposed limitations on the design of masonry lintels, all lintels must contain reinforcement. Concrete masonry lintels are not typically manufactured using shear reinforcement (stirrups or other vertical reinforcement). Therefore, this standard does not address issues related to such. For further guidance, refer to Building Code Requirements for Masonry Structures, TMS8201;402. Prestressed concrete lintels are not covered by this standard. 1.2 Lintels are manufactured using a no-slump concrete mix to provide a surface texture similar to that of concrete masonry. This specification applies to both machine-made and hand-tamped concrete masonry lintels intended for use in concrete masonry applications. 1.3 Concrete masonry lintels covered by this specification are made from lightweight or normal weight aggregates, or both. 1.4 This specification does not address the design or analysis of lintel capacity. Structural evaluations must be performed separately. The strength of a lintel is a function of factors including, but not limited to, the characteristics of the materials used in manufacturing (concrete materials and reinforcement), the amount and location of reinforcement, and the manufacturing and curing procedures. For design and analysis methods, refer to Building Code Requirements for Masonry Structures, TMS8201;402. 1.5 This specification does not cover U-shaped lintels or those of other cross-sections that are not 1008201;% solid. 1.6 This specification does not cover lintels of grouted concrete masonry lintels, or precast or cast-in-place lintels of slump concrete. 1.7 The text of this standard references notes and footnotes that provide explanatory material. These notes and footnotes (excluding those in tables and figures) shall not be considered as requirements of the standard. 1.8 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard. 1.9 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.

This European Standard is for prefabricated reinforced components of autoclaved aerated concrete to be used in building construction for: a) Structural elements:- loadbearing wall components; - retaining wall components; - roof components; - floor components; - linear components (beams and piers). b) Non-structural elements; - non-loadbearing wall components (partition walls); - cladding components (without fixtures) intended to be used for external facades of buildings; - small box culverts used to form channels for the enclosure of services; - components for noise barriers. Depending on the type and intended use of elements for which the components are utilized, the components can be applied - in addition to their loadbearing and encasing function - for purposes of fire resistance, sound insulation and thermal insulation indicated in the relevant clauses of this European Standard. Components covered by this standard are only intended to be subjected to predominantly non-dynamic actions, unless special measures are introduced in the relevant clauses of this European Standard. The term "reinforced" relates to reinforcement used for both structural and non-structural purposes. This European Standard does not cover; - rules for the application of these components in structures; - joints (except their strength and integrity E of resistance to fire); - fixtures; - finishes for external components, such as tiling. NOTE AAC components may be used in noise barriers if they are designed to fulfil also the requirements of EN 14388.
