1.1 本规范涵盖了在实验室中在材料和试验条件的精确控制下制作和养护混凝土试样的程序，所述混凝土使用的混凝土可以通过本文所述的杆压或振动固结。 1.2 以SI单位或英寸-磅单位表示的值应单独视为标准值。每个系统中陈述的值不一定完全等同；因此，为确保符合标准，每个系统应独立使用，两个系统的数值不得合并使用。 1.3 本标准并不旨在解决与其使用相关的所有安全性问题（如果有）。本标准的使用者有责任在使用前建立适当的安全、健康和环境实践并确定法规限制的适用性。( 警告- 新鲜的水硬性水泥混合物是腐蚀性的，长时间接触可能会对暴露的皮肤和组织造成化学灼伤。 2 ) 1.4 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》中确立的国际公认的标准化原则制定的。 ======意义和用途====== 4.1 本规范为实验室条件下的材料制备、混凝土搅拌、混凝土试件的制作和养护提供了标准化要求。 4.2 如果样本制备按本文规定进行控制，则样本可用于开发用于以下目的的信息:4.2.1 工程混凝土的配合比、 4.2.2 不同混合物和材料的评价， 4.2.3 与无损检测的相关性，以及 4.2.4 为研究目的提供标本。 附注1: 使用这种做法制作和养护的混凝土试件的混凝土试验结果被广泛使用。它们可能是项目混凝土验收测试、研究评估和其他研究的基础。仔细和知识渊博地处理材料、搅拌混凝土、成型试样和固化试样是必要的。许多执行这项重要工作的实验室都经过独立检查或认证。实践 C1077 确定和定义实验室人员的职责、责任和最低技术资格要求，以及用于测试混凝土和混凝土骨料的设备的最低要求。

1.1 This practice covers procedures for making and curing test specimens of concrete in the laboratory under accurate control of materials and test conditions using concrete that can be consolidated by rodding or vibration as described herein. 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. ( Warning— Fresh hydraulic cementitious mixtures are caustic and may cause chemical burns to exposed skin and tissue upon prolonged exposure. 2 ) 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. ====== Significance And Use ====== 4.1 This practice provides standardized requirements for preparation of materials, mixing concrete, and making and curing concrete test specimens under laboratory conditions. 4.2 If specimen preparation is controlled as stipulated herein, the specimens may be used to develop information for the following purposes: 4.2.1 Mixture proportioning for project concrete, 4.2.2 Evaluation of different mixtures and materials, 4.2.3 Correlation with nondestructive tests, and 4.2.4 Providing specimens for research purposes. Note 1: The concrete test results for concrete specimens made and cured using this practice are widely used. They may be the basis for acceptance testing for project concrete, research evaluations, and other studies. Careful and knowledgeable handling of materials, mixing concrete, molding test specimens, and curing test specimens is necessary. Many laboratories performing this important work are independently inspected or accredited. Practice C1077 identifies and defines the duties, responsibilities, and minimum technical qualification requirements of laboratory personnel and the minimum requirements for equipment used in testing concrete and concrete aggregates.
