Standard Specification for Packaged, Dry, Rapid-Hardening Cementitious Materials for Concrete Repairs 混凝土修补用包装的干燥快速硬化水泥基材料的标准规范
发布日期: 2020-09-01
1.1 本规范涵盖用于快速修复硬化水硬性水泥混凝土路面和结构的包装、干燥水泥砂浆或混凝土材料。不包括作为主要粘合剂的含有有机化合物的材料,如沥青、环氧树脂和聚合物。 1.1.1 包装、干燥的混凝土材料包含骨料,其中至少5%(按质量计)的总混合物保留在9.5-mm[ 3. / 8. -在中。]滤器 1.1.2 包装、干燥的砂浆材料包含总混合物质量百分比小于5%的骨料,保留在9.5 mm[ 3. / 8. -在中。]滤器 1.2 水溶液、水乳液或分散液可作为包装材料的成分。制造商可以指定这些液体来代替部分或全部混合水。 1.3 骨料必须作为包装材料的一部分。 制造商可能建议在其产品中添加特定数量和类型的额外骨料,以用于某些用途。然而,此类重新配制的产品不在本规范的范围内。 1.4 以国际单位制或英寸-磅单位表示的数值应单独视为标准值。每个系统中规定的值可能不是精确的等效值;因此,每个系统应相互独立使用。将两个系统的值合并可能会导致不符合标准。 1.5 以下安全隐患警告与本规范的测试方法部分有关: 本标准并非旨在解决与其使用相关的所有安全问题(如有)。本标准的用户有责任在使用前制定适当的安全、健康和环境实践,并确定监管限制的适用性。 1.6 本国际标准是根据世界贸易组织技术性贸易壁垒(TBT)委员会发布的《关于制定国际标准、指南和建议的原则的决定》中确立的国际公认标准化原则制定的。
1.1 This specification covers packaged, dry, cementitious mortar or concrete materials for rapid repairs to hardened hydraulic-cement concrete pavements and structures. Materials that contain organic compounds, such as bitumens, epoxy resins, and polymers, as the principal binder are not included. 1.1.1 Packaged, dry, concrete material contains aggregate of which at least 5 % by mass of the total mixture is retained on a 9.5-mm [ 3 / 8 -in.] sieve. 1.1.2 Packaged, dry, mortar material contains aggregate of which less than 5 % by mass of the total mixture is retained on a 9.5-mm [ 3 / 8 -in.] sieve. 1.2 Aqueous solutions, aqueous emulsions or dispersions may be included as components of the packaged materials. The manufacturer may specify that these liquids are to replace some or all of the mixing water. 1.3 Aggregates must be included as a component of the packaged materials. The manufacturer may recommend job site addition of specific amounts and types of additional aggregates to his product for some uses. However, such reformulated products are not within the scope of this specification. 1.4 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. 1.5 The following safety hazards caveat pertains to the test methods portion of this specification: 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. 1.6 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.
