Shrinkage-Compensating Concrete-Guide 补偿收缩混凝土导轨
发布日期: 2021-11-01
施工中使用补偿收缩混凝土,以减少干燥收缩裂缝。其特性与硅酸盐水泥混凝土相似。材料、比例、放置和养护应确保膨胀补偿了随后的干燥收缩。本指南阐述了确保混凝土膨胀应变发展的标准和实践。除了讨论基本原则外,还提供了方法和细节,包括结构设计细节和应用、混凝土混合料配比、浇筑、饰面和养护。本文件中描述的材料、工艺、质量控制措施和检查应仅由持有相应ACI证书或同等证书的个人进行测试、监控或执行(如适用)。
Shrinkage-compensating concrete is used in construction to minimize drying-shrinkage cracking. Its characteristics are similar to those of portland-cement concrete. The materials, proportions, placement, and curing should ensure that expansion compensates for subsequent drying shrinkage.This guide sets forth criteria and practices to ensure the development of expansive strain in concrete. In addition to a discussion of basic principles, methods and details are given covering structural design details and applications, concrete mixture proportioning, placement, finishing, and curing.The materials, processes, quality control measures, and inspections described in this document should be tested, monitored, or performed as applicable only by individuals holding the appropriate ACI certifications or equivalent.
