本指南介绍了纤维增强喷射混凝土（FRS）的技术和应用，重点介绍了合成纤维和钢纤维。它是ACI委员会506和ACI委员会544报告的文件中给出的信息之间的桥梁。描述了典型混合物的比例、配料、混合和应用程序，包括FRS所需的混合物比例和设备的修改。本文介绍了FRS的一般性能标准，尤其是开裂后的弯曲强度和韧性，以及其他典型性能和优点，如抗收缩开裂和抗冲击性的增强。并讨论了相应的测试方法。本文件介绍了FRS设计的一般注意事项。介绍了FRS的应用，包括隧道和采矿衬砌的施工和修复、边坡稳定、支护结构、火灾爆炸等- 抗剥落衬里和建筑结构。该报告还对FRS的规格和质量控制提供了指导。

This guide describes the technology and applications of fiber-reinforced shotcrete (FRS) with a focus on synthetic and steel macrofibers. It serves as a bridge between information given in documents reported by ACI Committee 506 and ACI Committee 544. Proportions of typical mixtures, batching, mixing, and application procedures are described, including modification of mixture proportions and equipment needed for FRS. General performance criteria of FRS, particularly postcracking flexural strength and toughness, are described along with other typical properties and benefits, such as increased resistance to shrinkage cracking and impact resistance. Corresponding test methods are also discussed. The document presents general FRS design considerations. Applications of FRS are described, including construction and repair of tunnel and mining linings, slope stabilization, retaining structures, fire-explosive-spalling-resistant linings, and architectural structures. The report also gives guidance on the specification and quality control of FRS.
