2023年6月23日 · Composite test methods (and specifications) for fiber-reinforced concrete structures. While initially focused on transitioning existing standards published by the American Concrete Institute, the relatively new ASTM Subcommittee D30.10 is developing new standardized test methods and material specifications for FRP composites.
Fiber-Reinforced Concrete Testing - Master Builders Solutions
Fiber-reinforced concrete’s ability to inhibit cracking when subjected to high impact or dynamic loads can be measured by testing its energy-absorption capacity. Master Builders Solutions provides this testing to help concrete producer partners identify toughness and flexural performance of their fiber-reinforced concrete.
FIP 8: Design & Specification of Fiber-Reinforced Concrete
Several useful documents on fiber-reinforced concrete (FRC) have been developed by ACI Committee 544 on Fiber-Reinforced Concrete, including the ACI 544.4R design guide. Criteria for the use of steel fibers as shear reinforcement is now provided in ACI 318.

2020年2月7日 · Fiber reinforced concrete (FRC) has been used for many different construction applications and many testing protocols have been developed to determine their mechanical behavior. The present paper focus on the comparisons between four major mechanical tests used for FRC: EN 14651, ASTM 1609, ASTM 1550 and EN 14488.
Today, there are a large variety of fiber options for reinforcing concrete available in the marketplace. These include micro and macro synthetic fibers, steel, and blended fibers, which are defined below. With so many options, it can be difficult to determine exactly what fiber is required for a given application.
