ACI PRC-544.11-22 PDF
Fiber-reinforced concrete (FRC) has become a viable choice for many designers and builders for the unique properties and advantages it provides. From slabs-on-ground to underground structures, the use of FRC has been expanding in concrete construction. This growth of applications has created the need to review the existing test methods for FRC and, where necessary, develop new ones. Two reports (ACI 544.2R and ACI 544.9R) have already been published regarding testing fresh properties and mechanical properties of FRC, respectively. This report is the third and final report on testing FRC for its durability properties, including shrinkage, creep, and permeability. Several standard and nonstandard test methods are presented in this report to represent some of the knowledge in this area.
This is a report on the current knowledge on testing timedependent properties of FRC, including shrinkage, creep behavior, and transport properties that affect the long-term durability. The objective of this report is to review some standard and nonstandard test methods available in the literature for better evaluating these properties. This document has summarized various published experiments; the results are presented to illustrate the test methodologies and should not be taken out of context or used for evaluating specific fibers. The results from the tests used in this document are not intended for direct use in design of FRC structures.
The purpose of this document is to provide a better understanding of the many factors influencing test results for the determination of such properties. This report applies to shrinkage, creep, and transport properties of conventional FRC using fibers classified in ASTM C1116/C1116M. This report excludes test results for ultra-high-performance concrete (UHPC) or engineered cementitious composites (ECCs), both with elevated dosages of fibers.
