Which AR Glass Rich Fibers are recommended for ready – mix concrete?
A. The type of AR Glass Rich Fiber to be used in ready – mixed concrete is determined by the application. HD Fibers perform very well as both a plastic shrinkage reinforcement and as a secondary reinforcement. While HP Fibers will also work in this context, it is also an excellent alternative to steel or synthetic fiber blends. HP used at higher rates provides post – first crack reinforcement where sustained loading after first is a consideration (C1018 & C1399 Applications).
